A front/rear split system uses one master cylinder section to pressurize the front caliper pistons and the other section to pressurize the rear caliper pistons. A split circuit braking system is now required by law in most countries for safety reasons; if one circuit fails, the other circuit can still stop the vehicle. Diagonal split systems were used initially on American Motors automobiles in the 1967 production year. The right front and left rear are served by one actuating piston while the left front and the right rear are served, exclusively, by a second actuating piston (both pistons pressurize their respective coupled lines from a single foot pedal).

The flowing water transports sediment and locally erodes the bedrock. Surface water drains via moulins to a subglacial system of conduits which allow flow into cavities in the ice. As the flow increases the head loss in the conduits increases, resulting in increasing water levels and correspondingly higher hydraulic pressure at the headwall of the glacier. As the conduits pressurize, they pressurize the cavities and the porous basal till.

Other maglev trains are already in use, which avoid much of the added costs of Hyperloop. The SCMaglev in Japan has demonstrated without a vacuum tube, by using an extremely aerodynamic train design. It also avoids the cost and time required to pressurize and depressurize the exit and entry points of a Hyperloop tube. There is also the criticism of design technicalities in the tube system.
|
|
Cooling air for the turbine vanes undergoes a similar process. Cooling the leading edge of the blade can be difficult, because the pressure of the cooling air just inside the cooling hole may not be much different from that of the oncoming gas stream. One solution is to incorporate a cover plate on the disc. This acts as a centrifugal compressor to pressurize the cooling air before it enters the blade.

Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids. Many compressors can be staged, that is, the fluid is compressed several times in steps or stages, to increase discharge pressure. Often, the second stage is physically smaller than the primary stage, to accommodate the already compressed gas. Each stage further compresses the gas and increases pressure.

In a seawater RO system operating at a 40% membrane water recovery rate, the ERD supplies 60% of the membrane feed flow. Energy is consumed by the circulation pump, however, because this pump merely circulates and does not pressurize water, its energy consumption is almost negligible: less than 3% of the energy consumed by the high pressure pump. Therefore, nearly 60% of the membrane feed flow is pressurized with almost no energy input.

In broadcast engineering, a desiccator may be used to pressurize the feedline of a high-power transmitter. Because it carries a large amount of energy from the transmitter to the antenna, the feedline must have low dielectric losses. Because it must also be lightweight so as not to overload the radio tower, air is often used as the dielectric. Since moisture can condense in these lines, desiccated air or nitrogen gas is pumped in.

This would reduce the flow of coolant through the oil cooler and cause higher oil temperatures. This sediment would also reduce the flow of coolant through the EGR cooler resulting in premature failure due to thermal expansion fatiguing the heat exchanging core. The early EGR coolers (2003-2004.5) were also susceptible to premature failure. \- With the use of Split-shot HEUI fuel injectors, high pressure oil is required to pressurize the fuel injectors.

Upon opening the nozzle valve, the water is pushed out through the nozzle as the pressurized air attempts to re-equilibrate with atmospheric pressure. This system allows pumping energy to be stored and used as needed. As well, unlike the methods noted above, this air pressure system allows production of a uniform, continuous stream of water. The limitation of this design is the need for a large number of strokes to pressurize a larger reservoir.

Its website describes the movement as "an expression of collective anger of people of India against corruption." It goes on to state: "We have all come together to force/request/persuade/pressurize the Government to enact the Jan Lokpal Bill. We feel that if this Bill were enacted it would create an effective deterrence against corruption." Anna Hazare, an anti-corruption crusader, began a fast- unto-death, demanding that this bill, drafted by Civil Society, be adopted.

The junta's lockdown. When it turned out that the prosecutors were slow to continue the Klongchan lawsuit with regard to Luang Por Dhammajayo, the DSI and several other police departments started to press charges against other people related to the temple. To further pressurize Luang Por Dhammajayo, the DSI also expanded its focus to branch centers of Wat Phra Dhammakaya. Branch centers in Nakhon Ratchasima, Chiangmai, Kanchanaburi, Loei, and Tak were investigated and charged with encroaching on nature reserves.

Pacocha sank quickly. Four men died immediately in the collision and sinking: her commanding officer, Capitán de Fragata (Ship Captain) Daniel Nieva Rodríguez, died securing the bridge access hatch; Teniente Segundo (Second Lieutenant) Luis Roca Sara and two enlisted men were trapped in flooded compartments and drowned. Twenty-three of her crew succeeded in abandoning ship. In the sinking submarine, Teniente (First Lieutenant) Roger Cotrina Alvarado secured the watertight forward torpedo room door and attempted to pressurize the compartment.

In some cases in jet engines the conditions in the engine due to airflow entering the engine or other variations can cause the compressor blades to stall. When this occurs the pressure in the engine blows out past the blades, and the stall is maintained until the pressure has decreased, and the engine has lost all thrust. The compressor blades will then usually come out of stall, and re-pressurize the engine. If conditions are not corrected, the cycle will usually repeat.

The sequential turbocharger system utilizes the smaller of the two turbos when the engine is running at low revolutions; once the engine has reached 2,800 rpm, the larger turbocharger is also used to pressurize the intake. Jaguar tested fitting the engine to its XK model but didn't carry the project over to production. The 3.0-litre variants used by Land Rover feature the 2.7-litre's off-roading adaptations plus calibration of the engine's electronics to allow the use of low-quality fuels.

In addition to these, the polymer should be resistant enough to be functional, such as handling the strain of being put under pressurize, and flexible so that it is easy to mold. There are no polymers that perfectly provide every one of these features. Therefore, researchers have turned their attention to copolymers: combinations of polymers that have chemical and mechanical properties that complement each other. This led to identifying poly(butylene adipate-co-terephthalate) (PBAT) as a potential copolymer for blending.

Cutaway of Space Shuttle external tank Autogenous pressurization is the use of self-generated gaseous propellant to pressurize liquid propellant in rockets. Traditional liquid-propellant rockets have been most often pressurized with other gases, such as helium, which necessitates carrying the pressurant tanks along with the plumbing and control system to use it. Autogenous pressurization has been operationally used on the Titan 34D and the Space Shuttle. Autogenous pressurization is planned to be used on the SLS, Starship, and Terran 1.

Chemical engineering is a discipline that was developed out of those practicing "industrial chemistry" in the late 19th century. Before the Industrial Revolution (18th century), industrial chemicals and other consumer products such as soap were mainly produced through batch processing. Batch processing is labour-intensive and individuals mix predetermined amounts of ingredients in a vessel, heat, cool or pressurize the mixture for a predetermined length of time. The product may then be isolated, purified and tested to achieve a saleable product.

During normal operation of a car engine, some vapors from the cylinder pass by the piston rings and down into the crankcase. Without ventilation this can pressurize the crankcase and cause issues such as lack of piston ring sealing and damaged oil seals. To avoid this, manufacturers created a crankcase ventilation system. Originally this was often a very basic setup where a filter was placed on the top of the cam case and the pressure and vapors were vented to atmosphere.

No hydrogen was in the tank when the explosion occurred. Under the direction of MSFC, a Board of Inquiry headed by Dr. Kurt H. Debus, Director of Kennedy Space Center, convened on the night of May 28. Immediate investigation revealed that the second shift crew, not knowing that the liquid hydrogen pressure sensors and switches had been disconnected, had attempted to pressurize the tank. Believing that a liquid hydrogen vent valve was leaking, the technicians closed the facility by blocking valves.

The Communications Authority received approximately 12,000 complaints criticising TVB's coverage for favouring the pro-establishment camp and the CCP. Protesters have claimed that TVB presented an over-simplified narrative with limited information, therefore avoiding more overt censorship methods. In light of this the Hong Kong branch of Pocari Sweat withdrew their advertisements from TVB to the delight of anti-extradition protesters while also angering Mainland consumers. Netizens have then launched a campaign to pressurize corporations to stop placing advertisements on TVB.

After Sindhu brings back JKB from his alcoholic state, JKB's friends pressurize Sindhu to leave the town and never come back, which she does the very next day. Both Bhairavi and JKB are distraught as Bhairavi had agreed to marry Sindhu to JKB. A couple of months later, during one of JKB's concerts, Sindhu is seen coming back and sitting down to listen to his music. However, she refuses to marry JKB, saying that she would not deny Bhairavi her rights.

Instead, in-field modifications to pressurize the turbopump gearboxes and use an oil with a different viscosity that was less prone to foaming were conducted. Modified bearing retainers were not installed. Subsequently, six consecutive Thor and Atlas launches failed during February–April 1958, several due to turbopump problems. The following four months did not include any turbopump failures, but the 17 August launch of the world's first lunar probe on Thor-Able 127 ended in an explosion due to a turbopump failure.

Slow, or gradual, decompression occurs slowly enough to go unnoticed and might only be detected by instruments. This type of decompression may also come about from a failure to pressurize as an aircraft climbs to altitude. An example of this is the 2005 Helios Airways Flight 522 crash, in which the pilots failed to check the aircraft was pressurising automatically and then to react to the warnings that the aircraft was depressurising, eventually losing consciousness (along with most of the passengers and crew) from hypoxia.

Blue Origin has indicated that they intend to make the engine commercially available, once development is complete, to companies beyond ULA, and also plans to utilize the engine in Blue Origin's own new orbital launch vehicle. As of March 2016, Orbital ATK was also evaluating Blue engines for its launch vehicles. The BE-4 uses liquid methane rather than more commonly used rocket fuels such as kerosene. This approach allows for autogenous pressurization, which is the use of gasified propellant to pressurize liquid propellant.

Both substances were loaded from special openings on the upper end of the cylinders, where a manual valve conveyed the liquid nitrogen in the tank to pressurize them at the moment of use. The filler pipe coupling of the lance was located in the lower part of the tank, beside the right cylinder. The lance has a control lever of lightweight alloy that connects to the tank through a hose. At the muzzle of the lance, a large flange ("cartoccia") has a double ignition system.

The ERD uses this high-pressure concentrate stream to pressurize the low-pressure seawater stream (stream [1] becomes stream [4]), which it then merges (with the aid of a circulation pump [B]) into the highest-pressure seawater stream created by the high-pressure pump [A]. This combined stream feeds the membranes [C]. The concentrate leaves the ERD at low pressure [5], expelled by the incoming feedwater flow [1]. Pressure exchangers save energy in these systems by reducing the load on the high pressure pump.

Rubber expansion joints are mainly manufactured by manual wrapping of rubber sheets and fabric reinforced rubber sheets around a bellows-shaped product mandrel. Besides rubber and fabric, reinforced rubber and/or steel wires or metal rings are added for additional reinforcement. After the entire product is built up on the mandrel, it is covered with a winding of (nylon) peel ply to pressurize all layers together. Because of the labor-intensive production process, a large part of the production has moved to eastern Europe and Asian countries.

Westinghouse developed a T1 air compressor, to be used in conjunction with special tires, to deflate the tires off-road, in soft mud or snow, and be able to pressurize them again after. It could be fitted under a maintenance work order, from October 1944. There was even a small capstan winch field kit made for the jeep, driven off the motor, for self-extracting, or pulling other jeeps trapped in mud or snow. The winch was very small, and made hand-cranking of the jeep impossible.

One engine per year was tested, randomly taken from the assembly workshops.Qualification Over Ariane’s Lifetime This confidence is very rare in the world of space engines. An unusual feature of the Viking engines is their water tank and water pump, used to cool the exhaust gasses of the gas generator. The hot exhaust of the gas generator is cooled by water injection to 620°C before being used to drive the three coaxial pumps (for water, fuel and oxidizer) and to pressurize the fuel tanks.

Attitude control was provided by J-2 engine gimbaling during powered flight and by the two APS modules during coast. Auxiliary Propulsion System Modules were used for three-axis control during coast phases, roll control during J-2 firings, and ullage for the second ignition of the J-2 engine. Each APS module contained two thrusters providing thrust for roll and pitch, another thruster for yaw, and one thruster for ullage. Each module contained its own propellant tanks of dinitrogen tetroxide and monomethyl hydrazine as well as compressed helium to pressurize its propellants.

During 1954, hydropneumatic suspension was introduced, which utilizes the same principle of a gas that compresses (nitrogen) and a fluid that does not; in this application, an engine-driven pump is used to pressurize the hydraulic fluid. Another such example was a US patent filed by Jarry Hydraulics during 1958. During the 1960s, the British Ministry of Technology sponsored research into theoretical studies into improved oleo-dampening technology. In 2012, it was proposed that the vibration-dampening qualities of the oleo strut could be enhanced by using semi-active control to adjust fluid viscosity.

Hydrostatic bearings are externally pressurized fluid bearings, where the fluid is usually oil, water or air, and the pressurization is done by a pump. Hydrodynamic bearings rely on the high speed of the journal (the part of the shaft resting on the fluid) to pressurize the fluid in a wedge between the faces. Fluid bearings are frequently used in high load, high speed or high precision applications where ordinary ball bearings would have short life or cause high noise and vibration. They are also used increasingly to reduce cost.

On the day of the explosion, the initial testing of the Crew Dragon's Draco thrusters was successful, with the accident occurring during the test of the SuperDraco abort system. Telemetry, high-speed camera footage, and analysis of recovered debris indicate the problem occurred when a small amount of dinitrogen tetroxide leaked into a helium line used to pressurize the propellant tanks. The leakage apparently occurred during pre-test processing. As a result, the pressurization of the system 100 ms before firing damaged a check valve and resulted in the explosion.

Because infiltration is uncontrolled, and admits unconditioned air, it is generally considered undesirable except for ventilation air purposes. Typically, infiltration is minimized to reduce dust, to increase thermal comfort, and to decrease energy consumption. For all buildings, infiltration can be reduced via sealing cracks in a building's envelope, and for new construction or major renovations, by installing continuous air retarders. In buildings where forced ventilation is provided, their HVAC designers typically choose to slightly pressurize the buildings by admitting more outside air than exhausting so that infiltration is dramatically reduced.

Kegerator containing a half-barrel keg. Kegerator, a portmanteau of keg and refrigerator, is a refrigerator that has been designed or altered to store and dispense kegs. By keeping the keg in a refrigerated environment and using CO2 to pressurize and dispense the keg, it will allow the contents to remain fresh and carbonated for an extended period of time, generally a couple of months. Specifically designed kegerators are available for both commercial and residential use, however a common refrigerator can be reconfigured into a kegerator with a kegerator conversion kit.

Established in 1972, Tamil New Tigers (TNT) was the precursor to the LTTE. After it was renamed as Liberation Tigers of Tamil Eelam and restructured under the leadership of Velupillai Prabhakaran, the group staged low key attacks against various government targets, including policemen and local politicians. During this period, LTTE was supported by Tamil United Liberation Front (TULF), which considered the militant organization as a tool to pressurize government to agree to their demands. TULF leader Appapillai Amirthalingam introduced Prabhakaran to N.S. Krishnan, who later became the first international representative of LTTE.

Take-off can occur when the vehicle's g-force exceeds local gravity (expressed as a multiple of g0). The thrust to weight ratio of rockets typically greatly exceeds that of airbreathing jet engines because the comparatively far greater density of rocket fuel eliminates the need for much engineering materials to pressurize it. Many factors affect a thrust-to-weight ratio. The instantaneous value typically varies over the flight with the variations of thrust due to speed and altitude along with the weight due to the remaining propellant and payload mass.

After they are removed from the vats, the olives are fed through a filling wheel, where employees scoop them by hand into aluminum cans running on a conveyor belt. A "Panama paddle packer" machine creates a 200-degree steam bath as cans are sealed tight with aluminum lids. Then giant pressure cookers, called retorts, pressurize the cans and their contents for 62 minutes at 242 degrees fahrenheit. After the cans cool, a labeling machine applies their identifications and sizes, from the smallest (size 12) to the largest (size 16).

The Titan IIIA or Titan 3A was an American expendable launch system, launched four times in 1964 and 1965, to test the Transtage upper stage which was intended for use on the larger Titan IIIC. The Transtage was mounted atop two core stages derived from the Titan II. The Titan IIIA was also used as the core of the Titan IIIC. The Titan IIIA made its first flight on 1 September 1964. However, the Transtage failed to pressurize, resulting in a premature cutoff and failure to reach orbit.

He later moved to Mysore on the request of a dying friend to take over the operation of his newspaper, Pauravani which was running in losses at the time. In 1947, during the Political integration of India, the Maharaja of Mysore was reluctant to accede to the Indian Union, which resulted in the "Mysore Chalo" movement to pressurize the maharaja into acceding. Due to the movement, congress leaders were arrested and press freedom was curbed by the Kingdom of Mysore. Doreswamy among other journalists are noted to have continued publishing their newspapers from undisclosed locations.

Nissan's Infiniti brand offers both laser- based and radar-based systems. Brake assist with preview function anticipates the need to apply emergency braking and pre-pressurize the brake system to help improve brake response. Intelligent brake assist (IBA) with forward emergency braking (FEB) (on QX80) uses radar to monitor approaching speed to the vehicle ahead, helping detect an imminent collision. It provides a two- stage warning to alert the driver, and if the driver takes no action, the system automatically engages the brakes to mitigate the collision speed and impact.

Lumbar provocative discography (also referred to as "discography" or discogram) is an invasive diagnostic procedure for evaluation for intervertebral disc pathology. It is usually reserved for persons with persistent, severe low back pain (LBP) who have abnormal spaces between vertebrae on magnetic resonance imaging (MRI), where other diagnostic tests have failed to reveal clear confirmation of a suspected disc as the source of pain, and surgical intervention is being considered. Needles are inserted through the back into the disc near the suspect area, guided by fluoroscopic imaging. Fluid is then injected to pressurize the disc, and any pain responses are recorded.

They spun up the spacecraft to its nominal roll rate, in preparation for the upcoming trajectory correction maneuver in mid- July. On July 8, a longer sequence of thrusters firings failed, apparently due to loss of the nitrogen gas needed to pressurize the fuel tanks. On July 24, the ISEE-3 Reboot Team announced that all attempts to change orbit using the ISEE-3 propulsion system had failed. Instead, the team said, the ISEE-3 Interplanetary Citizen Science Mission would gather data as the spacecraft flies by the Moon on August 10 and enters a heliocentric orbit similar to Earth's.

Along with Morten Frost (Denmark), Liem Swie King (Indonesia), Prakash Padukone (India) and his teammate Luan Jin he was one of the world's leading players in that era, known for his cool and steady play. In China he is nicknamed "sticky candy" (牛皮糖), owing to his much-used tactic of using long rallies to pressurize an opponent into making mistakes. Han won the 1985 IBF World Championships beating Morten Frost in the final. He also won a bronze medal at the 1983 IBF World Championships and played singles for China's world champion Thomas Cup (men's international) teams of 1982 and 1986.

Cabin Pressure and Bleed Air Control Panels on a upright Modern jetliners have environmental control systems (ECS) that manage the flow of cabin air. Outside air enters the engines and is compressed in the forward section, prior to the combustion section, ensuring no combustion products can enter the cabin. A portion of that compressed bleed air is used to pressurize the cabin. The ECS then recirculates some of that cabin air through HEPA filters, while the rest is directed to outflow valves, ensuring there is a constant supply of fresh, clean air coming into the cabin pressurization system at all times.

Southern Pacific Railroad's MC-2 class of steam locomotives was the first class to be ordered by and built for Southern Pacific (SP) as cab forward locomotives. They were built in 1909 following the design of SP's MC-1 class built earlier that year. The success of this locomotive model led to the design and introduction of the AC class of 4-8-8-2 cab forward locomotives in the 1930s and 1940s. In order to get the fuel oil from the tender to the opposite end of the locomotive where the firebox sat, SP had to pressurize the oil in the tender.

Tamil Arasu Kazhaga Manadu Tamil Arasu Kazhagam (Association for Tamil Autonomy) () was an Indian political party founded by M. P. Sivagnanam (Ma. Po. Si) in Tamil Nadu. It was established as an association in 1946. Its goals were to pressurize the Indian National Congress Government of the Madras Presidency to increase the use of Tamil in administration and education, to create an autonomous Tamil state out of a composite Madras Presidency and to soften the pro-Hindi stance of the Congress. The association was allied with the Congress during 1946–54 and worked against the Dravidian Movement.

In 1974 University of California at Irvine chemist Frank Sherwood Rowland suggested that long-lived organic halogen compounds, such as the CFCs then widely used to pressurize spray cans, would reach the stratosphere where they would be dissociated by UV light, releasing chlorine atoms. Abplanalp wrote to the Chancellor of UC Irvine to complain about Rowland's public statements. At the time of Abplanalp's death in Bronxville, New York from lung cancer on August 30, 2003, age 81, he held more than 300 aerosol-related patents. He is interred at the Gate of Heaven Cemetery in Hawthorne, New York.

The V-2 rocket used hydrogen peroxide decomposed by a liquid sodium permanganate catalyst solution as a gas generator. This was used to drive a turbopump to pressurize the main LOX-ethanol propellants. In the Saturn V F-1 and Space Shuttle main engine, some of the main propellant was burned to drive the turbopump (see gas-generator cycle and staged combustion cycle). The gas generator in these designs uses a highly fuel-rich mix to keep flame temperatures relatively low. The Space Shuttle auxiliary power unit and the F-16 emergency power unit (EPU) use hydrazine as a fuel.

Parallel arrangements typically require the use of a bypass or diverted valve to allow one or both compressors to feed the engine. If no valve were employed and both compressors were merely routed directly to the intake manifold, the supercharger would blow backwards through the turbocharger compressor rather than pressurize the intake manifold, as that would be the path of least resistance. Thus a diverter valve must be employed to vent turbocharger air until it has reached the pressure in the intake manifold. Complex or expensive electronic controls are usually necessary to ensure smooth power delivery.

A pair of Malossi reed valve blades made from carbon fibre Reed valves are commonly used in high-performance versions of the two-stroke engine, where they control the fuel-air mixture admitted to the cylinder. As the piston rises in the cylinder a vacuum is created in the crankcase beneath the piston. The resulting pressure differential opens the valve and the fuel-air mixture flows into the crankcase. As the piston descends, it raises the crankcase pressure causing the valve to close to retain the mixture and pressurize it for its eventual transfer through to the combustion chamber.

A Bridgman seal, invented by and named after Percy Williams Bridgman, can be used to seal a pressure chamber and compress its contents to high pressures (up to 40,000 MPa), without the seal leaking and releasing the pressure The top is outside the pressure vessel; the bottom is inside. The topmost cylinder is the drive piston; it has an external force applied to it to pressurize the vessel.The six squares are cross-sections through three rings; the topmost (dark gray) one is a hard material, the middle one a softer one, and the bottom one a much softer one. Bridgman originally used hard steel, softer steel, and rubber.

A typical Kawai cell 8–6 multi-anvil apparatus uses air pumps to pressurize oil, which drives a vertical hydraulic ram to compress a cylindrical cavity known as a hatbox. This cavity is filled with six steel anvils, three facing up and three facing down, that converge on a set of eight tungsten carbide cubes. The interior corners of these cubes truncated to fit an octahedral assembly. These octahedra range from 8 mm to 25 mm on edge and are typically composed of MgO or another material that deforms ductilely over the range of experimental conditions, to make sure the experiment is under hydrostatic stress.

As two-stroke engines use their crankcase to pressurize the air:fuel mixture before transfer to the cylinder, any standard lubricating oil left there (per practice with four-stroke engines) would be swept up and burnt with the fuel. To provide cylinder lubrication, fuels supplied to two-stroke engines are often mixed with oil so that it can coat the cylinders and bearing surfaces along its path. The ratio of gas to oil is set by the engine manufacturer but ranges from 30:1 to 50:1 per volume unit. Oil remaining in the mixture is burnt with the fuel and results in a familiar blue smoke and odor.

However, a "growing body of reporting indicates that some of these charities are being used to aid Islamic extremist groups that engage in terrorism." Aid to the local Bosnian Islamist party (the SDA) gave it leverage to undermined competing local secular and more traditional Muslim groups. The SDA prohibited consumption of alcohol and pork, "brought Muslim religious instruction into the schools, opened up prayer rooms, and used the leverage of its distribution of aid to pressurize the population to adopt Muslim names, to wear the veil, and grow beards." A 1992 conference on the protection of human rights in Bosnia brought together representatives from 30 Muslims countries.

Of course, a higher pressure within a stairwell makes it harder to open doors from the building interior to the enclosed vestibules and to the enclosed stairwell. The Life Safety Code requires that the pressure differential across the barrier not be so great as to prevent the door from opening with a force of 30 lbf (133 N) at the door knob or handle. These 'pressurization' problems are, of course, non-existent with naturally ventilated smokeproof enclosures. The fans and air ducts used to pressurize the stairwell are life-critical systems, and are required to be enclosed in non-combustible, likewise two hour rated, construction.

Conventional wet sump engines have one oil pump. It is generally located inside the lower part of the engine, usually below and/or to one side of the crankshaft. On dry sump engines, at least two oil pumps are required: one to pressurize and distribute the oil around the engine components, and at least one other 'scavenge pump' to evacuate the oil which has pooled at the bottom of the engine. This scavenge pump is sometimes (but not always) located in the 'sump' of the engine, and crucially, this scavenge pump's flow-rate capacity must exceed that of the pump which pressurizes and distributes oil throughout the engine.

The British High Commissioner Alan Cunningham asked his government to pressurize Syria to stop the invasion of the mandate territory by the ALA by threatening that the British Army would take action. On January 20, 1948, a second ALA Battalion, a 630-soldier-strong First Yarmuk battalion, led by the Syrian officer Mohammed Safa, entered Palestine. It crossed the Damia Bridge over the Jordan River in a long convoy. An attempt by the British police to prevent their entry failed because of the intervention of the Arab Legion, and so the invasion was not stopped by the British in spite of protests from the Jewish Agency.

Advantages of hydro-mechanical drain cleaners are their eco-friendliness (most use only tap water), their ability to dislodge and remove clogs like sand or cat litter that 'back-fill when using a conventional snake, and their friendliness to plumbing joints. Unlike air-burst cleaners, hydro-mechanical drain cleaners do not pressurize plumbing joints. On some models of hydro- mechanical drain cleaner both hot and cold water can be used, providing added cleaning power for fat, protein, or other easily melting drain clogs. Disadvantages of hydro-mechanical drain cleaners included limited reach into drain plumbing, and the necessity of a water source to act as the motive agent.

This led to difference of opinion, and a group started campaigning to pressurize Ali to punish the rebels. It is the opinion of the Sunnis that A'isha and her party had intended to peacefully reconcile between these differing views. Initially, Ali did perceive the campaign of A'isha and her party as civil disobedience, so he made an effort to emphasize the importance of unity in the Muslim community. It is said that Ali appealed to the early hardships that the Muslim community had faced during Islam's inception, and referred back to the stability and peace the community experienced in the later days due to the community's unity and integration.

In 1993, CAT and International Truck & Engine Corporation introduced "hydraulically actuated electronic unit injection" (HEUI), where the injectors are no longer camshaft-operated and could pressurize fuel independently from engine RPM. First available on Navistar's 7.3L /444 cuin, V8 diesel engine. HEUI uses engine oil pressure to power high-pressure fuel injection, where usual method of unit injector operation is the engine camshaft. HEUI applications included the Ford 7.3L and 6.0L Powerstroke used between May 1993 and 2007. International also used the HEUI system for multiple engines including the DT 466E, DT 570, T-444E, DT-466–570, MaxxForce 5, 7, 9, 10, MaxxForce DT and VT365 engines.

A typical Kawai cell 8-6 multi-anvil apparatus uses air pumps to pressurize oil, which drives a vertical hydraulic ram to compress a cylindrical cavity known as a hatbox. This cavity is filled with six steel anvils, three facing and three facing down, that converge on a set of eight tungsten carbide cubes. The interior corners of these cubes truncated to fit an octahedral assembly. These octahedra range from 8 mm to 25 mm on edge and are typically composed of MgO or another material that deforms ductilely over the range of experimental conditions, to make sure the experiment is under hydrostatic stress.

The most recent method of fuel injection that is still in use today is called common rail injection. Common rail injection is a completely revolutionary design to fuel injection since a fuel pump is now used to pressurize a rail and then from there sends the fuel to each injector. A major benefit of switching over to this fueling system was how it allowed for much less leakage into the cylinders pre and post ignition. This is all possible since this fuel system operated upwards of 2600 bar so they are able to set spring tension higher in each injector to allow for more precise fuel injection and timing.

Earlier hydraulic automatic transmissions were almost always less energy efficient than manual transmissions due mainly to viscous and pumping losses (parasitic losses), both in the torque converter and the hydraulic actuators. 21% is the loss on a 3-speed Chrysler Torqueflite compared to a modern GM 6L80 automatic. A relatively small amount of energy is required to pressurize the hydraulic control system, which uses fluid pressure to determine the correct shifting patterns and operate the various automatic clutch mechanisms. However, with technological developments some modern continuously variable transmissions are more fuel-efficient than their manual counterparts and modern 8-speed automatics are within 5% as efficient as a manual gearbox.

Once the train has stopped, the braking system will not recharge (pressurize) until the emergency valve has been closed. This means a member of the train crew must locate the open valve, and ascertain that there is no problem which would make it unsafe to release the brakes and proceed. Identification of the valve is possible by the sound of air escaping from it. In many cars (and practically all cars built post-WWII), the communicating cord was only located in the vestibule, unless the car was of such a type that it did not have a vestibule, such as a dining or lounge car.

This can be avoided if the pressure cooker is regularly cleaned and maintained in accordance with the manufacturer's instructions and never overfilled with food and/or liquid. Modern pressure cookers typically have two or three redundant safety valves and additional safety features, such as an interlock lid that prevents the user from opening the lid when the internal pressure exceeds atmospheric pressure, preventing accidents from a sudden release of hot liquid, steam and food. If safety mechanisms are not correctly in place, the cooker will not pressurize the contents. Pressure cookers should be operated only after reading the instruction manual, to ensure correct usage.

A modern bar soda gun The process of dissolving carbon dioxide in water is called carbonation. Commercial soda water in siphons is made by chilling filtered plain water to or below, optionally adding a sodium or potassium based alkaline compound such as sodium bicarbonate to reduce acidity, and then pressurizing the water with carbon dioxide. The gas dissolves in the water, and a top-off fill of carbon dioxide is added to pressurize the siphon to approximately , some higher than is present in fermenting champagne bottles. In many modern restaurants and drinking establishments, soda water is manufactured on-site using devices known as carbonators.

The liquid oxygen flows through an anti-flood valve that prevents it from entering the heat exchanger until sufficient heat is present for the heat exchanger to utilize the heat contained in the gases discharged from the HPOTP turbine, converting the liquid oxygen to gas. The gas is sent to a manifold and then routed to pressurize the liquid oxygen tank. Another path enters the HPOTP second-stage preburner pump to boost the liquid oxygen's pressure from 30 to 51 MPa (4,300 psia to 7,400 psia). It passes through the oxidizer preburner oxidizer valve into the oxidizer preburner, and through the fuel preburner oxidizer valve into the fuel preburner.

Work on the Corporal F with turbo pump instead of compressed air pressure propellant feed was halted with few parts produced.and the Corporal G study of a chemical gas generator to pressurize the fuel tanks was terminated as well.The Rockets and Missiles of WHITE SANDS PROVING GROUNDS 1945-1958, by Gregory P. Kennedy, p 118, Schiffer Military History, Atglen, PA, 2009 The Corporal E was designed by JPL, with the first 4 airframes built by Douglas Aircraft Company, rocket motors and telemetry equipment were produced by JPL, Sperry Gyroscope provided the autopilot, Army Ordinance the Doppler and Position transponder, and the Signal Corps the radar tracking beacon.

The fuel is also circulated around the outside of the combustion chamber and nozzle to prevent it from overheating. The electric-pump-fed engine is a bipropellant rocket engine in which the fuel pumps are electrically powered, and so all of the input propellant is directly burned in the main combustion chamber, and none is diverted to drive the pumps. This differs from traditional rocket engine designs, in which the pumps are driven by a portion of the input propellants. An electric cycle engine uses electric pumps to pressurize the propellants from a low-pressure fuel tank to high-pressure combustion chamber levels, generally from to .

At the start of his career, he would find people in challenging circumstances with the help of Tehsil-Daar Syed Sabtain Shah and then pressurize his victims using the help of a sub-inspector Syed Qamber Ali Shah in Dera Ismail Khan. His gang of land mafia now always works in close coordination with the Revenue Authorities and support from the local police. His usual course of action is to find a piece of land owned by some poor citizen, usually nowadays in his own constituency near Bannu and Lakki Marwat, and then selling it off in small pieces to his numerous front men.

FIRST Steamworks, stylized as FIRST STEAMworks, was the FIRST Robotics Competition game for the 2017 season. As in past games, two alliances of three individual teams and their robots compete on a field to score "match" point to win the game and ranking points to advance to playoff rounds. The game has a steampunk theme and teams are required to shoot wiffle balls which represent fuel into a simulated boiler which transfers the generated steam into an airship in the middle of the field. Each alliance has one airship, which they pressurize with steam from the boiler and load with plastic gears from the field.

Interlocking metal pan roof systems installed on mobile homes can fail under the pressure differential (lift) created by the high velocity winds passing over the surface plane of the roof. This is compounded by the wind entering the building allowing the building interior to pressurize lifting the underside of the roof panels, resulting in destruction of the building. One example of pan roof systems can be found in this document from Structall Building Systems. To mitigate this pressure differential, pre-installed aluminum tabular channels can be permanently fastened perpendicularly across the top of the interlocking ribs of the metal roof system without disturbing the flow of rainwater at the eaves, mid-span, and ridge locations of the building.

This not only reduced the amount of coolant needed to remove a given amount of energy, and thereby reduced the physical size of the core, but also increases the efficiency of the turbines used to extract this energy for electrical generation. WR-1 ran with outlet temperatures up to 425 °C, compared to about 310 °C in the conventional CANDU. This also meant that there is no need to pressurize the cooling fluid beyond what is needed to force it through the cooling tubes at the required rate. This allowed the fuel tubes to be made thinner, reducing the number of neutrons lost in interactions with the tubing, and further increasing the neutron economy.

Madho Singh considered the British as ‘Bendra’ or lowborn race due to their lack of consideration of Indian nobility and relentless greed for grabbing land by any means possible. The British ignored the legitimate rights of Surendra Sai to the throne in their own favor and falsely imprisoned him for punishing the rebellious Zamindar of Rampur within his right to authority over his land. The revenue tax demands from the British swelled up to eight times putting additional burden on the local estate rulers to pressurize their subjects for paying more taxes. The Zamindars and other chiefs beholding high sense of honor among their subjects were ordered to personally deposit the amounts at Sambalpur.

There existed a cordial relationship between the British at Fort St George and Zuddie Khan, the Mughal Foujdar of Bengal and Southern India with the frequent exchange of letters and gifts. However, the relationships with Nawab Dawood Khan and his successor Zulfikar Khan weren't so cordial. However, from April 1710, the Nawab under the suspected influence of Yavallappa, Manager of Poonamallee, began to pressurize the Company to hand over the Five Old Villages. Fraser wrote a letter to Zulfikar Khan reminding him that the Five Old Villages had been handed over to the British by the Mughal Emperor Aurangazeb in recognition of the services they had rendered to the Mughals during the siege of Gingee.

Echolocating bats couple sound production with the mechanisms engaged for flight, allowing them to reduce the additional energy burden of echolocation. Instead of pressurizing a bolus of air for the production of sound, laryngeally echolocating bats likely use the force of the downbeat of their wings to pressurize the air, cutting energetic costs by synchronizing wingbeats and echolocation. The loss of echolocation (or conversely, the lack of its evolution) may be due to the uncoupling of flight and echolocation in megabats. The larger average body size of megabats compared to echolocating bats suggests a larger body size disrupts the flight- echolocation coupling and made echolocation too energetically expensive to be conserved in megabats.

Most modern wells are planned to include gas pipeline transport, but some oil wells are drilled only to get the more lucrative oil, in which case the options are to locally use, process, or dispose of the APG. A traditional local use is to re-inject the gas for storage, and to re-pressurize the well to extend the oil production lifetime. On-site processing with various mobile systems also exist for producing natural gas liquids (NGL), compressed natural gas (CNG), liquified natural gas (LNG), and gas to liquids (GTL) fuels that can be transported by truck or ship. Electricity generation from on-site microturbines and engines is also compatible with minimally processed APG.

Backpacker: A Problem Solving Manual for Use in the Wilds, p.94 (Ten Speed Press 1982) but reports from years of field use of the Svea on the Appalachian Trail indicate that it has the lowest record of clogging among stoves used on the trail. Some common but nonrecommended practices can adversely affect the Svea's performance and reliability. For example, when using a wind screen or shield other than the built-in wind screen (such as the flexible aluminum foil windscreens used with stoves made by Mountain Safety Research), care should be taken not to wrap the windscreen too tightly around the stove because this may cause the stove to overheat and the fuel tank to over-pressurize.

Aero Union, under contract to the USFS, has developed an improved version of the system, known as the MAFFS II. The new system has a capacity of up to , replacing the five retardant tanks with one large tank, and has two on-board air compressors. The original MAFFS has to be pressurized by a compressor on the ground as a part of the loading process. The ability to pressurize the system in the air cuts turn-around time significantly.MAFFS 2 information from USFS The new system discharges the retardant through a special plug in the paratroop drop door on the side of the aircraft, rather than requiring the cargo ramp door to be opened; this allows the aircraft to remain pressurized during the drop sequence.

Until the early part of the 20th century, most natural gas associated with oil was either simply released or burned off at oil fields. Gas venting and production flaring are still practised in modern times, but efforts are ongoing around the world to retire them, and to replace them with other commercially viable and useful alternatives. Unwanted gas (or stranded gas without a market) is often returned to the reservoir with 'injection' wells while awaiting a possible future market or to re-pressurize the formation, which can enhance oil extraction rates from other wells. In regions with a high natural gas demand (such as the US), pipelines are constructed when it is economically feasible to transport gas from a wellsite to an end consumer.

After the founding of the Bulygin Duma in 1905, the radicals in the Union of Unions, alongside the Social Democrats, became more determined than ever to use "mass civil disobedience" as a weapon to pressurize the government to make further reforms and concessions, even though liberals chose not to boycott the elections to the Duma.Figes, p. 187. During the general strike in September 1905, after the most educated and wealthy of the working class – the printers – had gone on strike, the railway workers, and the Union of Railway Employees and Workers, followed suit. The union was affiliated with the Union of Unions, which themselves at the time had been discussing the possibility of a political general strike to aid their campaign for further reform for several months.

On October 25, 1999, a month after the American team rallied to win the Ryder Cup and four months after his U.S. Open victory, Stewart was killed in the crash of a Learjet flying from his home in Orlando, Florida, to Texas for the year-ending tournament, The Tour Championship, held at Champions Golf Club in Houston. National Transportation Safety Board (NTSB) investigators concluded that the aircraft failed to pressurize and that all on board died due to hypoxia as the aircraft passed to the west of Gainesville, Florida. The aircraft continued flying on autopilot until it ran out of fuel and crashed into a field near Mina, South Dakota. At the time of his death, Stewart had won $12,673,193 in career earnings.

Xploderz is a line of toy weapons made by The Maya Group to compete with Hasbro's Nerf Super Soaker line and marketed as a safer alternative to paintball. The concept is based on Orbeez, a girls' toy line also by The Maya Group that uses water-absorbent gel pellets,Orbeez - official site and hence is sometimes referred to as "Orbeez ball shooters". When playing, a piston rod is manually pulled back against spring tension in a fashion similar to drawing a slingshot, allowing pellets to be drop-loaded from a top mounted magazine. When the rod is released, the spring elasticity drives piston to pressurize the air pump behind the pellets, which in turn propels the pellets flying out forward.

In 2014, when Justice Maheshwari was District & Sessions Judge, Jaipur Metropolitan, he came to the rescue of entire lower judiciary in the state by protecting his subordinate Additional District and Sessions Judge Mahendra Singh Chaudhary on 7 July 2014 who felt offended by a group of lawyers attempting to pressurize him to recall a judicial order passed against an advocate Bharat Bhushan Pareek evicting him from a tenanted premises of an old couple. By taking a bold step, Judge Chaudhary brought it on record and called it contemptuous. The order was supported by Justice Maheshwari despite protest and threats from the Bar. It triggered a complete strike on 9 July 2014 by around one lakh lawyers in 800 courts across the state demanding transfer of both the judges by calling their actions anti-lawyer activities.

A jet injector being used in mass vaccinations, 1976 swine flu outbreak, United States. A jet injector is a type of medical injecting syringe device used for a method of drug delivery known as jet injection, in which a narrow, high-pressure stream of liquid penetrates without needle the outermost layer of the skin (stratum corneum) to deliver medication to targeted underlying tissues of the epidermis or dermis ("cutaneous" injection, also known as classical "intradermal" injection), fat ("subcutaneous" injection), or muscle ("intramuscular" injection). The jet stream is usually generated by the pressure of a piston in an enclosed liquid-filled chamber. The piston is usually pushed by the release of a compressed metal spring, although investigational devices may use piezoelectric effects and other novel technologies to pressurize the liquid in the chamber.

As civil engineers, telecom engineers provide the modern communications backbone for all technological communications distributed throughout civilizations today. Unique to telecom engineering is the use of air-core cable which requires an extensive network of air handling equipment such as compressors, manifolds, regulators and hundreds of miles of air pipe per system that connects to pressurized splice cases all designed to pressurize this special form of copper cable to keep moisture out and provide a clean signal to the customer. As political and social ambassador, the OSP engineer is a telephone operating company's face and voice to the local authorities and other utilities. OSP engineers often meet with municipalities, construction companies and other utility companies to address their concerns and educate them about how the telephone utility works and operates.

On 7 November 1966, a peaceful assembly of people from all religions of India, led by ascetics and also backed by Congress members (Indian National Congress), Rashtriya Swayamsevak Sangh and Bharatiya Jana Sangh (aka Jan Sangh), attempted to circle the Indian Parliament in a bid to pressurize legislators to, fulfill the one of the 10 constitutional plegdes, of totally banning cow slaughter, in Independent India. The episode was the culmination of a long-term movement by the Indian peoples (Hindu, Jain, Sikh, tribals, Parsi, Including representative of other minorities) Right to protect the cow, a traditional symbol of reverence in Hindu society. A meeting in late 1965 involving lobbying groups and influential Hindu religious orders initiated a year-long program of demonstrations and picketing, culminating in the planned march to the Parliament. Jan Sangh was a participant in the march.

However, some authors have argued that the implausibly high porosity requirement could be overlooked if extremely high pore pressures were supplied by tectonic activity associated with the concurrent formations of the Elysium and Tharsis Rises, likely through the effects of extensional faulting. If extensional stresses built up gradually in the vicinity of Cerberus Fossae, any tectonic activity would relieve this extensional stress, causing a relative compression that would pressurize the reservoir. Nearby diking, however, would add large amounts of material into the vicinity of the reservoir, compressing it and rapidly pressurizing it. Any rupturing and faulting associated with this tectonic activity would penetrate the overlying cryosphere (in a dry and cold Amazonian Mars); to compensate for its pressurization, reservoir fluids would be forced upwards through the fissure, forming the outflow channel morphologies observed on the surface.

Mondeville, Calvados, France A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a water distribution system for the distribution of potable water, and to provide emergency storage for fire protection. Water towers often operate in conjunction with underground or surface service reservoirs, which store treated water close to where it will be used. Other types of water towers may only store raw (non-potable) water for fire protection or industrial purposes, and may not necessarily be connected to a public water supply. Water towers are able to supply water even during power outages, because they rely on hydrostatic pressure produced by elevation of water (due to gravity) to push the water into domestic and industrial water distribution systems; however, they cannot supply the water for a long time without power, because a pump is typically required to refill the tower.

Helium Quad - Breathing gas storage asset Gas storage and blending equipment are provided to pressurize and flush the system, and treatment gases should be available appropriate to the planned storage depths. Bulk stock of premixed gas is usually provided to suit the planned depth of the operation, and separate bulk stock of helium and oxygen to make up additional requirements, adjust chamber gas composition as the oxygen is used up, and mix decompression gas. Bulk gas is usually stored in manifolded groups of storage cylinders known as "quads", which usually carry about 16 high pressure cylinders, each of about 50 litres internal volume mounted on a frame for ease of transport, or larger frames carrying larger capacity high pressure "tubes". These tube frames are usually designed to be handled by intermodal container handling equipment, so are usually made in one of the standard sizes for intermodal containers.

The brake actuator has an electric pump that provides the hydraulic pressure for the system, and valves to pressurize each wheel caliper to apply the friction brake when required by the system. The system includes all of the complexity of a vehicle stability control system (VSC), antilock brake system (ABS), and the requirement to use the Regeneration Braking as the primary mode of slowing the vehicle unless the Traction Battery (high-voltage battery) state of charge is too high to accept the additional energy or a panic stop or ABS situation is detected by the system. The sensors monitored as inputs for the brake system include the wheel speed sensors, traction battery state of charge, yaw sensor, brake pedal, stroke sensor, steering wheel angle, hydraulic actuator pressure, hydraulic pressures of each wheel caliper circuit, and accelerator position. Other information and inputs are also monitored.

This piston presses against a hard steel ring, followed by a softer steel ring, and then a ring of more viscous or elastic material such as rubber, copper or soap stone, all within the channel. These three intermediate stages provide an inner cylinder, and the third stage bears on a specially shaped final steel piston that applies the force to pressurize material held at the end of the outer, enclosing channel. The final piston consists of a wider portion that fills the main channel, and a narrower cylindrical extension that leads back through the inner channel formed by the three ring-shaped intermediate stages, ending within the hard steel ring without making direct contact with the driving piston. This arrangement ensures that higher pressures create tighter seals that resist any leakage from the material at the end, since the pressure within the last and softest ring is greater than that in the material at the end.

The Hydramatic used a two-element fluid coupling (not a torque converter, which has at least three elements, the pump, turbine and stator although Roto HydraMatic has a fluid coupling and a fixed stator) and three planetary gearsets, providing four forward speeds plus reverse. Standard ratios for the original Hydra-Matic were 3.82:1, 2.63:1, 1.45:1 and 1.00:1 in automotive applications, and 4.08:1, 2.63:1, 1.55:1 and 1.00:1 in light truck and other commercial applications. The Controlled Coupling HydraMatic used 3.97:1, 2.55:1, 1.55:1, and 1.00:1. Roto Hydramatic 375 a three speed, four range automatic has a 3.56:1, 2.93:1, 1.56:1 and 1.00:1. Roto Hydramatic 240 a three speed, four range automatic has ratios of 3.64:1, 3.03:1, 1.57:1 and 1.00:1 The Hydramatic was fitted with two pumps to pressurize its hydraulic control system and provide lubrication of internal components.

Building airtightness levels can be measured by using a fan, temporarily installed in the building envelope (a blower door) to pressurize the building. Air flow through the fan creates an internal, uniform, static pressure within the building. The aim of this type of measurement is to relate the pressure differential across the envelope to the air flow rate required to produce it. Generally, the higher the flow rate required to produce a given pressure difference, the less airtight the building. The fan pressurization technique is also described in many standard test methods, such as ASTM E779 - 10,ASTM, Standard E779-10, “Test Method for Determining Air Leakage by Fan Pressurization”, ASTM Book of Standards, American Society of Testing and Materials, Vol. 4 (11), 2010 ASTM E1827 – 11,ASTM, Standard E1827-11, “Standard Test Methods for Determining Airtightness of Buildings Using an Orifice Blower Door”, ASTM Book of Standards, American Society of Testing and Materials, Vol.

These two texts are also the only two sources that explicitly mention that the substance was heated over a furnace before being discharged; although the validity of this information is open to question, modern reconstructions have relied upon them. Proposed reconstruction of the Greek fire mechanism by Haldon and Byrne Based on these descriptions and the Byzantine sources, John Haldon and Maurice Byrne designed a hypothetical apparatus as consisting of three main components: a bronze pump, which was used to pressurize the oil; a brazier, used to heat the oil (πρόπυρον, propyron, "pre-heater"); and the nozzle, which was covered in bronze and mounted on a swivel (στρεπτόν, strepton). The brazier, burning a match of linen or flax that produced intense heat and the characteristic thick smoke, was used to heat oil and the other ingredients in an airtight tank above it, a process that also helped to dissolve the resins into a fluid mixture. The substance was pressurized by the heat and the usage of a force pump.

IPK with inflatable trousersIntermittent pneumatic compression is a therapeutic technique used in medical devices that include an air pump and inflatable auxiliary sleeves, gloves or boots in a system designed to improve venous circulation in the limbs of patients who suffer edema or the risk of deep vein thrombosis (DVT) or pulmonary embolism (PE). In use, an inflatable jacket (sleeve, glove, trousers or boot) encloses the limb requiring treatment, and pressure lines are connected between the jacket and the air pump. When activated, the pump fills the air chambers of the jacket in order to pressurize the tissues in the limb, thereby forcing fluids, such as blood and lymph, out of the pressurized area. A short time later, the pressure is reduced, allowing increased blood flow back into the limb. The primary functional aim of the device “is to squeeze blood from the underlying deep veins, which, assuming that the valves are competent, will be displaced proximally.” When the inflatable sleeves deflate, the veins will replenish with blood.

Prior to release of the vehicle stack for liftoff, the SRBs must simultaneously ignite and pressurize their combustion chambers and exhaust nozzles to produce a thrust derived, net counter-rotating moment exactly equal to the SSME's rotating moment. With the SRBs reaching full thrust, the hold-down bolts are blown, releasing the vehicle stack, the net rotating moment is zero, and the net vehicle thrust (opposing gravity) is positive, lifting the orbiter stack vertically from the launch pedestal, controllable through the coordinated gimbal movements of the SSMEs and the SRB exhaust nozzles. During ascent, multiple all-axis accelerometers detect and report the vehicle's flight and orientation (referencing the flight deck aboard the orbiter), as the flight reference computers translate navigation commands (steering to a particular waypoint in space, and at a particular time) into engine and motor nozzle gimbal commands, which orient the vehicle about its center of mass. As the forces on the vehicle change due to propellant consumption, increasing speed, changes in aerodynamic drag, and other factors, the vehicle automatically adjusts its orientation in response to its dynamic control command inputs.
