The normal start of a meander for craft is Halfpenny Bridge, Lechlade. The finish is often Teddington Lock but other points in London are used.

The drawings depict a streamlined envelope with internal ballonets that could be used for regulating lift. The airship was designed to be driven by three propellers. In 1784 Jean-Pierre Blanchard fitted a hand-powered propeller to a balloon, the first recorded means of propulsion carried aloft.Winter & Degner (1933), pp. 26–27.

FLIP is designed to study wave height, acoustic signals, water temperature and density, and for the collection of meteorological data. Because of the potential interference with the acoustic instruments, FLIP has no means of propulsion. It must be towed to open water, where it drifts freely or is anchored. FLIP is 700 gross tons.

The vessel's main power plants consist of two four-stroke diesel engines made by Krupp MaK Maschinenbau GmbH, each developing at 900 revolutions/minute. The propeller is driven via a gear mechanism. Using this means of propulsion, the Sea Cloud II achieves a top speed of about 13 knots. Additionally, she is equipped with a bow thruster.

In chronological order, spacecraft are listed equipped with electric space propulsion. This includes both cruise engines and/or thrusters for attitude and orbit control.

Velella moves by sailing. Velella, the by-the- wind sailor, is a cnidarian with no means of propulsion other than sailing. A small rigid sail projects into the air and catches the wind. Velella sails always align along the direction of the wind where the sail may act as an aerofoil, so that the animals tend to sail downwind at a small angle to the wind.

Physalia physalis The Portuguese man o' war (Physalia physalis) lives at the surface of the ocean. The gas-filled bladder, or pneumatophore (sometimes called a "sail"), remains at the surface, while the remainder is submerged. Because the Portuguese man o' war has no means of propulsion, it is moved by a combination of winds, currents, and tides. The sail is equipped with a siphon.

Even to the present day, dhows make commercial journeys between the Persian Gulf and East Africa using sails as their only means of propulsion. Their cargo is mostly dates and fish to East Africa and mangrove timber to the lands in the Persian Gulf. They often sail south with the monsoon in winter or early spring, and back again to Arabia in late spring or early summer.

Found mostly in tropical and subtropical waters, the Atlantic Indian Portuguese man o' war lives at the surface of the ocean. The gas-filled bladder, or pneumatophore, remains at the surface, while the remainder is submerged. Portuguese man o' war have no means of propulsion, and move passively, driven by the winds, currents, and tides. Strong winds may drive them into bays or onto beaches.

The inertialess field consumes enormous amounts of energy and collapses after a few seconds.Icon #39 Rocket can fly by releasing her inertia field's kinetic energy beneath her, launching her skyward. Initially, she was not very skilled with this ability and thus could only leap over great distances.Icon #24 However, after training from Darnice, Rocket can use her kinetic energy as a means of propulsion for genuine flight.

At times, especially with gentle descents, double poling is the sole means of propulsion. On uphill terrain, techniques include the "side step" for steep slopes, moving the skis perpendicular to the fall line, the "herringbone" for moderate slopes, where the skier takes alternating steps with the skis splayed outwards, and, for gentle slopes, the skier uses the diagonal technique with shorter strides and greater arm force on the poles.

Oars were used when near the coast or in a river, to gain speed quickly, and when there was an adverse (or insufficient) wind. In combat, the variability of wind power made rowing the chief means of propulsion. The ship was steered by a vertical flat blade with a short round handle, at right angles, mounted over the starboard side of the aft gunwale. Longships were not fitted with benches.

The game is a 2D side-scroller, with most of the levels involving various means of propulsion. The main method is a laser gun worn as a jetpack that shoots a laser beam with a time limit. Many variations on this, such as a shotgun that launches the player at a great distance, or a slingshot effect that flings the player from wall to wall, are used at different levels.

The Soyuz/Fregat launcher provided most of the thrust Mars Express needed to reach Mars. The final stage of the Fregat was jettisoned once the probe was safely on a course for Mars. The spacecraft's on-board means of propulsion was used to slow the probe for Mars orbit insertion and subsequently for orbit corrections. The body is built around the main propulsion system, which consists of a bipropellant 400 N main engine.

List of bicycle types Bicycles can be categorized in different ways: e.g. by function, by number of riders, by general construction, by gearing or by means of propulsion. The more common types include utility bicycles, mountain bicycles, racing bicycles, touring bicycles, hybrid bicycles, cruiser bicycles, and BMX Bikes. Less common are tandems, lowriders, tall bikes, fixed gear, folding models and recumbents (one of which was used to set the IHPVA Hour record).

A full-floating axle can be identified by a protruding hub to which the axle shaft flange is bolted. The semi-floating axle setup is commonly used on half-ton and lighter 4x4 trucks in the rear. This setup allows the axle shaft to be the means of propulsion, and also support the weight of the vehicle. The main difference between the full- and semi-floating axle setups is the number of bearings.

Throughout their long history, galleys relied on rowing as the most important means of propulsion. The arrangement of rowers during the 1st millennium BC developed gradually from a single row up to three rows arranged in a complex, staggered seating arrangement. Anything above three levels, however, proved to be physically impracticable. Initially, there was only one rower per oar, but the number steadily increased, with a number of different combinations of rowers per oar and rows of oars.

The term pulling was also used historically.W B Woodgate Boating Read Books, 2008 Sweep or single oar rowing has a long history and was the means of propulsion for Greek triremes and Viking longboats. These boats were wide enough for the pairs of rowers to sit alongside each other. Boats can go faster, the narrower they are, because a smaller cross-sectional area reduces drag and wave drag and gives a sharper angle to the bow.

SNCF engineers were delighted at the performance; this attempt represented a beginning into the study of using electricity as the means of propulsion for high speed rail. When leaving the factory, BB 9001 and 9002 wore a two-color livery (dark bluish green and light bluish green) with aluminum stripes down the centerline, similar to the 2D2 9100s released shortly before them. 9001 and 9002 were later repainted in a uniform dark bluish green paint scheme.

Single seater Thames punts were normally made only 2 feet (60 cm) wide, and somewhat shorter than a standard punt; very few of these are still afloat. Racing punts, which are still used by a few specialist clubs on the lower Thames, may be built even narrower. Thames punts have occasionally been adapted for other means of propulsion: including sails, tow-ropes, and paddle wheels. With the addition of iron hoops and canvas awnings, punts have also been used for camping.

In aquatic salamanders and in frog tadpoles, the tail has dorsal and ventral fins and is moved from side to side as a means of propulsion. Adult frogs do not have tails and caecilians have only very short ones. Salamanders use their tails in defence and some are prepared to jettison them to save their lives in a process known as autotomy. Certain species in the Plethodontidae have a weak zone at the base of the tail and use this strategy readily.

Legal Information Institute, Cornell Law School. (retrieved 4 April 2020). "Gyrodyne means a rotorcraft whose rotors are normally engine-driven for takeoff, hovering, and landing, and for forward flight through part of its speed range, and whose means of propulsion, consisting usually of conventional propellers, is independent of the rotor system." In the helicopter, the spinning rotor blades draw air down through the rotor disc; to obtain forward thrust, the rotor disc tilts forward so that air is also blown backwards.

Their flattened tail is the primary means of propulsion in the water. When on the surface, they may use their legs for maintaining balance. Although their partially webbed feet often are mentioned, this webbing is very marginal and no greater in extent than in the green iguana, a species that also shares the flattened tail. Marine iguanas have powerful limbs with long, sharp claws for climbing, holding onto rocks and pulling themselves forward when at the sea bottom (adding to the propulsion provided by the tail).

Their flattened tails and short legs, which probably ended in webbed feet, would have been their main means of propulsion in the water. The parietal eye on top of the head assisted the animal with orientation, rather than its vision, and its presence is regarded as a primitive characteristic. The vertebral processes of Placodus dove-tailed into each other and were firmly connected, so that the trunk was rigid. The abdomen was covered with a special armor formed of the bent, right-angled abdominal ribs.

Hu and Bush conclude that meniscus climbing is an unusual means of propulsion in that the insect propels itself in a quasi-static configuration, without moving its appendages. Biolocomotion is generally characterized by the transfer of muscular strain energy to the kinetic and gravitational potential energy of the creature, and the kinetic energy of the suspending fluid. In contrast, meniscus climbing has a different energy pathway: by deforming the free surface, the insect converts muscular strain to the surface energy that powers its ascent.

Astro has machine guns on his backside like in the 1980s series, however this time they fire actual bullets, instead of lasers. His finger lasers “digibeam” is absent. Instead of the arm cannon in the 2003 series, it is changed to full arm blasters in both arms. Also, his arm rockets are absent, although his arm cannons can also serve as a means of propulsion. In the 1980s series, Astro’s eyes act as lights, while in the 2003 series they allow him to analyze things.

The La Crosse Queen is a modern-day replica of the grand river boats that plied the Mississippi River in the late 19th century. She is one of the few authentic Mississippi River paddlewheel river boats still in operation in the country today. In keeping with early traditions, she was built with split sternwheels that are her only means of propulsion. The La Crosse Queen has a split sternwheel and each is run by a twin diesel engine that powers hydraulic motors which turn the paddles.

George Medhurst (1759–1827) was a mechanical engineer and inventor, who pioneered the use of compressed air as a means of propulsion. His ideas led directly to the development of the first atmospheric railway. He was born in Shoreham, Kent and trained as a clockmaker at Clerkenwell, London, but later became interested in pneumatics. In 1799, he filed a patent for a wind pump for compressing air to obtain motive power and the following year he patented his ‘Aeolian’ engine which used compressed air to power vehicles.

In 1936, a young engineer named Hans von Ohain had taken out a patent on using the exhaust from a gas turbine as a means of propulsion. He presented his idea to Ernst Heinkel, who agreed to help develop the concept. Von Ohain successfully demonstrated his first engine, the Heinkel HeS 1 in 1937, and plans were quickly made to test a similar engine in an aircraft. The He 178 was designed for von Ohain's third engine design, the HeS 3, which burned diesel fuel.

From there, Malpica's mission would be to attack the Huerista gunboat Guerrero, operating out of Guaymas. After destroying the Guerrero, Tampico would begin a commerce raiding campaign against targets along the west coast of Mexico. Tampico had steamed only thirty miles when her one remaining boiler had burned out of action, rendering the Constitutionalist saliors stranded with no means of propulsion. Repairs to the boiler were attempted, but proved fruitless, eventually Captain Malpica requested that the American destroyer tow Tampico into Altata, eighty miles away.

The Rifle Grenade General Service (RGGS) was a rifle grenade of Israeli design in service with the British Army as the L86 since 1996.They Work For You They superseded the L74A1 and L75A1, these being the Luchaire 40mm in AC and AP/AV configurations respectively. As with its predecessors, the grenade's means of propulsion is of the bullet-trap type and is launched from the muzzle of the L85A2 rifle using standard ball ammunition. For maximum accuracy a dedicated prismatic sight can be attached to the rifle.

It transpired, however, that developments in shipbuilding technology led to several of the new amenities having to be rebuilt and expanded almost as soon as they were finished. Docks and locks at the south- west corner of No 3 Basin; the building with the chimney is No 1 Pumping Station, beyond which is the former gun-mounting workshop. Technological change affected not only ships' means of propulsion, but the materials from which they were built. By 1860 wooden warships, vulnerable as they were to modern armaments, had been rendered largely obsolescent.

It could in principle be built using known technology. ; Gravity Niven can conceive of four ways of generating artificial gravity in a spaceship: (1) centrifugal force; (2) adding mass, e.g. neutronium or a black hole (this would incur serious penalties in fuel consumption); (3) gravity waves; and (4) continuous linear acceleration to the midway point of a journey, followed by continuous deceleration. ; Flying Cities These were proposed by James Blish (192175) in his novel sequence Cities in Flight (195662); they used an as-yet-undiscovered means of propulsion.

This is in contrast to most Mississippi River paddlewheelers in operation today that have a "free wheeling" paddlewheel at the stern of the boat for visual effect, but have traditional screw-type engines hidden for their real means of propulsion. The boat is divided into two levels, the upper deck and the lower deck. The upper deck is covered by a canopy and is open at the sides so that guest can enjoy the scenic view and feel of the breeze. The lower deck consists of a galley, dining room, bar area and heads.

The game follows an unnamed male protagonist as he chases his future self, who has been captured, through time for an unknown reason. Central to the game is a powerful laser gun received from the Future Protagonist that can be used as both a weapon and a means of propulsion. A running gag is that, just as a character is about to explain what's going on, they are interrupted, keeping the protagonist - and the player - in the dark. The plot contains elements of time travel, the time paradox effect, and alternate time-lines.

Its limpid, globular eyes, which appear red or blue, depending on lighting, are proportionately the largest in the animal kingdom at in diameter. The name of the animal was inspired by its dark colour, cloaklike webbing, and red eyes, rather than habit—it feeds on detritus, not blood. Dorsal view Oral view Mature adults have a pair of small fins projecting from the lateral sides of the mantle. These earlike fins serve as the adult's primary means of propulsion: vampire squid move through the water by flapping their fins.

Rafting equipment has continuously evolved and developed significantly from old rubber WW II era military surplus rafts. Modern whitewater rafts are typically made with advanced nylon or Kevlar infused plastics like PVC or urethane; though many of the more entry-level low-cost manufacturers still use a glued rubber. Plastic is generally more durable, longer-lasting, and just as easy to repair compared to older rubber rafts. Paddles and oars are the typical means of propulsion for rafts and come in many sizes and varieties with specific river conditions in mind.

A Fiat Uno in 2018 A vehicle is any non-living device that is used to move people and goods. Unlike the infrastructure, the vehicle moves along with the cargo and riders. Unless being pulled by a cable or muscle-power, the vehicle must provide its own propulsion; this is most commonly done through a steam engine, combustion engine, or electric motor, though other means of propulsion also exist. Vehicles also need a system of converting the energy into movement; this is most commonly done through wheels, propellers and pressure.

A free-flying hot air balloon A balloon is an unpowered aerostat which has no means of propulsion and must be either tethered on a long cable or allowed to drift freely with the wind. Although a free balloon travels at the speed of the wind, it is travelling with the wind so to a passenger the air feels calm and windless. To change its altitude above ground it must either adjust the amount of lift or discard ballast weight. Notable uses of free-flying balloons include meteorological balloons and sport balloons.

The failure of Schienenzeppelin has been attributed to everything from the dangers of using an open propeller in crowded railway stations to fierce competition between Kruckenberg's company and the Deutsche Reichsbahn's separate efforts to build high-speed railcars. One disadvantage of the rail zeppelin was the inherent difficulty of pulling additional wagons to form a train, because of its construction. Furthermore, the vehicle could not use its propeller to climb steep gradients, as the flow would separate when full power was applied. Thus an additional means of propulsion was needed for such circumstances.

The interval of ninety years between the end of the Napoleonic Wars in 1815 and the beginning of the Russo-Japanese War in 1904 was marked by no major naval war. There was fighting at sea, and there were prolonged blockades, but there were no campaigns between large and well-appointed navies. During this period an entire revolution took place in the means of propulsion, armament and construction of ships. Steam was applied to warships, at first as an auxiliary force, in the second quarter of the 19th century.

Naval warfare in the ancient world can be traced back to the Mediterranean in the third millennium BC, from evidence of paintings in the Cyclades and models of ships which were made across the Aegean. Ships were used for civilian transport and trade, as well as for military purposes. They were propelled by both rowing and sailing, but since the Mediterranean is known for its inconsistent weather patterns, rowing was probably the primary means of propulsion. The first documented, physical evidence of a naval battle is found in a relief painting located in the temple of Medinet Habu, near Luxor, Egypt.

Cockpit of classic racing yacht, Moonbeam of Fife, under sail in 2008 A sailing yacht (US ship prefixes SY or S/Y), is a leisure craft that uses sails as its primary means of propulsion. A yacht may be a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies here to sailing vessels that have a cabin with amenities that accommodate overnight use. To be termed a "yacht", as opposed to a "boat", such a vessel is likely to be at least in length and have been judged to have good aesthetic qualities.

Satisfied with the performance of both the machinery and the crew, Wilkins and his men left the relative safety of coastal waterways for the uncertainty of the North Atlantic on 4 June 1931. Soon after the commencement of the expedition the starboard engine broke down, and soon after that the port engine followed suit. On 14 June 1931 without a means of propulsion Wilkins was forced to send out an SOS and was rescued later that day by the USS Wyoming. The Nautilus was towed to Ireland on 22 June 1931, and was taken to England for repairs.

A Fiat Uno in 2018 A vehicle is a non-living device that is used to move people and goods. Unlike the infrastructure, the vehicle moves along with the cargo and riders. Unless being pulled/pushed by a cable or muscle-power, the vehicle must provide its own propulsion; this is most commonly done through a steam engine, combustion engine, electric motor, a jet engine or a rocket, though other means of propulsion also exist. Vehicles also need a system of converting the energy into movement; this is most commonly done through wheels, propellers and pressure.

A man riding an electric bicycle Bicycles can be categorized in many different ways: by function, by number of riders, by general construction, by gearing or by means of propulsion. The more common types include utility bicycles, mountain bicycles, racing bicycles, touring bicycles, hybrid bicycles, cruiser bicycles, and BMX bikes. Less common are tandems, low riders, tall bikes, fixed gear, folding models, amphibious bicycles, freight bicycles, recumbents and electric bicycles. Unicycles, tricycles and quadracycles are not strictly bicycles, as they have respectively one, three and four wheels, but are often referred to informally as "bikes" or "cycles".

As they lack mechanical compressors, scramjets require the high kinetic energy of a hypersonic flow to compress the incoming air to operational conditions. Thus, a scramjet-powered vehicle must be accelerated to the required velocity (usually about Mach4) by some other means of propulsion, such as turbojet, railgun, or rocket engines. In the flight of the experimental scramjet-powered Boeing X-51A, the test craft was lifted to flight altitude by a Boeing B-52 Stratofortress before being released and accelerated by a detachable rocket to near Mach4.5. In May 2013, another flight achieved an increased speed of Mach5.1.

This is the official urgency voice call. (pronounced ) Meaning "I, my vessel or a person aboard my vessel requires assistance but is not in distress." This overrides all but a mayday call, and is used, as an example, for calling for medical assistance or if the station has no means of propulsion. The correct usage is: > PAN-PAN, PAN-PAN, PAN-PAN All stations, all stations, all stations THIS IS > [vessel name repeated three times] My position is [position as a lat-long > position or bearing and distance from a fixed point] I am [type of urgency, > e.g.

56-59 Thanks to hyperdrive technology, Star Wars ships can cover interstellar distances which would normally requires thousands of years in a matter of hours. Deep Space 1 was the first NASA's spacecraft to use ion propulsions, with comparisons made directly between it and the Empire's TIE Fighter. According to NASA, while their means of propulsion were the same, advances in power generation would be needed to in order to develop an ion engine as powerful as those used on TIE fighters. The space probe Dawn also uses ion propulsion, although unlike the TIE fighter it was fitted with three instead of just two.

A reliable means of propulsion for the submerged vessel was only made possible in the 1880s with the advent of the necessary electric battery technology. The first electrically powered boats were built by the Polish engineer Stefan Drzewiecki in Russia, James Franklin Waddington and the team of James Ash and Andrew Campbell in England, Dupuy de Lôme and Gustave Zédé in France and Isaac Peral in Spain. In 1884, Drzewiecki converted 2 mechanical submarines, installed on each a 1 hp engine with the new, at the time, source of energy - batteries. On tests submarine went under the water against the flow of the Neva River at a rate of 4 knots.

The 16 water-color drawings published the following year depict a streamlined envelope with internal ballonnets that could be used for regulating lift: this was attached to a long carriage that could be used as a boat if the vehicle was forced to land in water. The airship was designed to be driven by three propellers and steered with a sail-like aft rudder. In 1784, Jean-Pierre Blanchard fitted a hand-powered propeller to a balloon, the first recorded means of propulsion carried aloft. In 1785, he crossed the English Channel in a balloon equipped with flapping wings for propulsion and a birdlike tail for steering.

Sometimes, they use their maxillary barbels (attached to the upper jaw) to lure prey fish closer to their mouths, similar to a worm jerking in the water, although this behavior is contested by some aquarists, who do not observe this behavior. When the catfish is ready to strike, the Chaca will open its large mouth rapidly, creating a vacuum that pulls in water and its prey, which may be up to half the fish's own length. These fish are also able to use this large mouths as a means of propulsion; when frightened, they will gulp a large amount of water and expel it through their gills.

Between the wars, wood was largely replaced in part or whole by metal tubing, and finally aluminum stressed skin structures (monocoque) began to predominate. By World War II, most fighters were all-metal monoplanes armed with batteries of machine guns or cannons and some were capable of speeds approaching . Most fighters up to this point had one engine, but a number of twin-engine fighters were built; however they were found to be outmatched against single-engine fighters and were relegated to other tasks, such as night fighters equipped with primitive radar sets. Hawker Sea Hurricanes in formation By the end of the war, turbojet engines were replacing piston engines as the means of propulsion, further increasing aircraft speed.

Crew also have to go onto deck to confirm there are no ropes or lines being dragged in the water that could wrap around a propeller before starting any internal combustion engine as a secondary means of propulsion. Dismasting are rarely life-threatening after the initial event and the broken mast is cut away. However, dismastings appear to have contributed to the loss of life at sea as a consequence of crews abandoning an otherwise perfectly seaworthy vessel in favor of a life raft. This has led to a sailing adage to always “Step up into the life raft.” In other words, to never abandon the sailboat unless it is confirmed that it is really sinking.

As a result, the Thistle was given a two-masted sailing rig as a supplementary means of propulsion, along with a number of other anachronistic features such as a manual capstan to raise the anchor, and candles rather than light bulbs. Policy changes shortly after the Thistle's launch meant that no further gunboats would be built for the Royal Navy, and the use of sail propulsion was strongly discouraged. Nonetheless, problems with using Thistle's engines for long-range cruising would prompt the restoration of her sailing rig in 1919, while her usefulness on colonial stations meant that she was refitted to maintain her capabilities in the 1920s, acquiring an anti- aircraft armament.

In 1955 astronomer and UFO researcher Morris K. Jessup, the author of the just published book The Case for the UFO, about unidentified flying objects and the exotic means of propulsion they might use, received two letters from Carlos Miguel Allende (who also identified himself as "Carl M. Allen" in another correspondence) who claimed to have witnessed a secret World War II experiment at the Philadelphia Naval Shipyard. In this experiment, Allende claimed the destroyer escort was rendered invisible, teleported to New York, teleported to another dimension where it encountered aliens, and teleported through time, resulting in the deaths of several sailors, some of whom were fused with the ship's hull.Barna William Donovan (2011). Conspiracy Films: A Tour of Dark Places in the American Conscious, McFarland. p.

Widgeon proved to be slightly faster than Archimedes in smooth seas, but Chappell concluded that as the latter had a lower horsepower-to-weight ratio, the screw propeller as a means of propulsion had proven "equal, if not superior, to that of the ordinary paddle- wheel."Fincham, pp. 346–348. This finding was more decisive than it may appear, because from a naval perspective, screw propulsion had only to prove itself approximately equal in efficiency to paddlewheel propulsion, as paddlewheels had well recognized shortcomings in military use. These included the exposure of the paddlewheel and its engines to enemy fire, as well as the reduction of space available for the placement of cannon which impinged upon a warship's broadside firepower.

Vehicle electrification is a topic that covers many aspects of electrification in vehicles. It may cover vehicles with electrical means of propulsion, such as an electric car, as well as electricity playing a role in their functionality. Voltages vary widely between applications. In general, vehicle electrification refers to efforts to design mild to full hybrid vehicle to full electric vehicles as well as converting some of the non-electrical vehicle systems like hydraulic suspension-systems to smart electro-magnetic suspensions, or All-Wheel-Drive (AWD) to eAWD where AWD is automatically engaged only under certain conditions (like certain low vehicle speed range) to leave more juice for full electric vehicle range as opposed to AWD all the time which sips more juices from battery.

Initially named a coaling station due to the use of coal for steam generation a fuelling station was built for the purpose of replenishing coal supplies for ships or railway locomotives. The term is often associated with 19th and early 20th century seaports associated with blue water navies, who used coaling stations as a means of extending the range of warships. In the late 19th century steamships powered by coal began to replace sailing ships as the principal means of propulsion for ocean transport. Fueling stations transitioned to oil as boilers moved from being coal-fired to oil- or hybrid oil-and-coal-firing, coal being completely replaced as steam engines gave way to internal combustionEncyclopædia Britannica, Fourteenth Edition, Volume Pg 899, 1938 and gas turbine power plants.

Often there can be no interaction between two ships even when both are in hyperspace. This effect can be used as a plot device; because they are invisible to each other while in hyperspace, ships will encounter each other most often around contested planets or space stations. Hyperdrive may also allow for dramatic escapes as the pilot "jumps" to hyperspace in the midst of battle to avoid destruction. In many stories, for various reasons, a starship cannot enter or leave hyperspace too close to a large concentration of mass, such as a planet or star; this means that hyperspace can only be used after a starship gets to the outside edge of a solar system, so the starship must use other means of propulsion to get to and from planets.

Watercolor of United States ships at the battle of Valcour Island, depicting several row galleys A row galley was a term used by the early United States Navy for an armed watercraft that used oars rather than sails as a means of propulsion. During the age of sail row galleys had the advantage of propulsion while ships of sail might be stopped or running at slow speed because of lack of wind for their sails. While called galleys, they were based on different hull type than the Mediterranean galley, the term being used mainly due to the employment of oars.All Canada in the Hands of the British: General Jeffery Amherst and the 1760, Douglas R. Cubbison, page 106 Row galleys were often fitted with sails in addition to the oars.

Claret jug presented to Smith in 1858, at The Mariners MuseumAs a boy he had acquired great skill in the construction of model boats and took special interest in their means of propulsion. This fascination with boats remained with him and in 1834 on a reservoir near his farm, he perfected the propulsion of a model boat by means of a wooden screw driven by a spring. He became utterly convinced that this form of propulsion was greatly superior to the paddle wheel which was in use at the time. The following year he built a superior model with which he performed a number of experiments at Hendon and in 1836 took out a patent for propelling vessels by means of a screw revolving beneath the water at the stern.

On 20 January 2007, during the Antarctic summer, Team N2i became the first people to reach the Antarctic pole of inaccessibility without powered aid, using kite skiing as their primary means of propulsion."UK team makes polar trek history", BBC news story, retrieved June 2007 There is a small segment of kiters that participate in GPS speed competitions where kiters record speed data on a GPS unit and submit it to a coordinating body for comparison to other kiter's speeds. In the StormboardingStormboarding world wide speed ranking Joe Levins, an American kiter, was the first to reach 70 mph/112 km/h in 2008. In 2009 Christopher Krug, an American kiter sponsored by Peter Lynn KiteboardingPeter Lynn Kiteboarding pushed the envelope further to a speed of 73.5 mph/118 km/h.

The Royal Navy was still for the most part a sailing Navy at this stage, with steam providing auxiliary power rather than the main means of propulsion; this was to change over the course of the next thirty years. The rebuilt Sheerness, which had been designed primarily for the repair and maintenance of sailing ships, soon found itself having to adapt to the changing demands of steam technology. Most particularly, because Chatham Dockyard was not expanded and adapted for steam until the 1860s, Sheerness found itself under pressure to provide interim facilities for repair and maintenance of steam-powered ships based in the Nore. This became an immediate priority with the outbreak of the Crimean War: so in 1854, a new Steam Factory was built 'in haste' at Sheerness by Godfrey Greene, with the second mast house being converted into an engineering foundry and fitting shop.

NASCAR Craftsman Truck Series Notes (Week of July 14), July 18, 1997, Retrieved December 14, 2007 In June 1994, the speedway hosted the graduating class of nearby William S. Hart High School after the stadium at College of the Canyons was deemed unsafe for occupancy; a consequence of the Northridge Earthquake. The graduation resulted in two new track records: the fastest lap by unmotorized participants, as well as the slowest lap by any means of propulsion. The track closed unexpectedly on July 19, 1995 in the middle of the season after the grandstands had been red-tagged and condemned by the County of Los Angeles, and have since been torn down. Some say that the track was actually closed due to home developments that had sprouted around the surrounding area of the track and too many residents started to complain about loud engine noise.

USS Donald Cook receives fuel during a replenishment at sea (RAS) with RFA Wave Ruler. The RFA was first established in 1905 to provide coaling ships for the Navy in an era when the change from sail to coal-fired steam engines as the main means of propulsion meant that a network of bases around the world with coaling facilities or a fleet of ships able to supply coal were necessary for a fleet to operate away from its home country. Since the Royal Navy of that era possessed the largest network of bases around the world of any fleet, the RFA at first took a relatively minor role. The RFA firstly became heavily relied on by the Royal Navy during World War II, when the British fleet was often far from available bases, either due to the enemy capturing such bases, or, in the Pacific, because of the sheer distances involved.

It has been debated that Roberto would have reached these levels of his abilities of his own accord, and that Gideon's experimentation only increased his evolution process. The fact that the solar blasts were concussive in origin led directly into X-Force #28, where Sunspot thinks of using them as a means of propulsion, and thus fly by blasting in the opposite direction of where he wanted to go – initially leaving a slight trail behind him, but in later years, Roberto would learn to use the propulsion more subtly – to appear to hover in place with no blast wake at all other than his usual "powered up" corona effect. His capacity to fly has similarly been enhanced as he is able to breach planetary orbit and reach Saturn's belt with relative ease.Hulk Vol 3 #3-4 Sunspot also had the rituals and ideas of the Askani inside his head, due to a telepathic contact with Cable.

The term chelandion is derived from the Greek word kelēs, "courser", and first appeared during the early 8th century.. In the medieval Latin used in Western Europe, it was rendered chelandium or scelandrium (and thence the 12th-century sandanum transport), while the Arabs rendered the name as shalandī (plural shalandiyyāt) and used it for a probably similar type of vessels in their own navies.. In common with the general characteristics of the dromōn type, the chelandion was a bireme galley, i.e. with two rows of oars, which provided its main means of propulsion, although it also featured one or two lateen sails, and was steered by two quarter rudders at the stern. It could also be equipped with siphons for projecting the feared Greek fire, the Byzantine navy's secret incendiary weapon. The term chelandion is usually used interchangeably with dromōn in medieval literary sources, leading to much confusion as to the exact nature of the ship and its differences with the dromōn proper.

First appeared in Evangelion 3.0, has an appearance near-identical to that of Unit 01, excluding having four eyes and arms. Its most distinctive feature is the Double Entry system of two entry plugs, with the two pilots capable of seeing each other as if they were in a single plug; either pilot is capable of controlling the EVA on their own, although both of them working in tandem is preferred. Unusually, the EVA does not appear to have an AT-field, instead using a number of remote- controlled drones called RS Hoppers to protect itself; these drones are each capable of deploying their own AT-field, can fly without any apparent means of propulsion and explode violently when damaged. Without these drones, the EVA does not appear to have any offensive weaponry but is immune to progressive blades and specialized anti-AT ammunition fired by Unit 08 fails to affect it whatsoever.

HMS Thistle would retain a sailing rig for the rest of her career. The Thistle seems to have no longer had her main topmast by 1919, as the mainmast was demoted to become the mizzen, and the ship adopted what was effectively a ketch sailplan, with a jib in the bows, a tall square-rigged foremast carrying a mainsail and topsail, and two fore-and-aft sails on the shorter mizzen, a staysail and a trysail spanker. Subsequently, she adopted a reduced rig of just three sails - her jib, one square sail on the foremast, and a single fore-and-aft sail on the mizzen. Although the sails were only used in conjunction with the engines, the fact that the Thistle had returned to sail as a means of propulsion distinguishes her from a number of other Royal Navy warships which resumed the use of staysails to improve their seakeeping and stationkeeping ability (a practice which was not fully abandoned until HMS Reclaim paid off in 1979).

In 1940, paleontologists Alfred Romer and Llewellyn Ivor Price proposed that hindlimbs with a greater length than forelimbs was another aquatic adaptation of Ophiacodon, supposedly because the hindlimbs would have been used to propel it through water. Several of these features are no longer thought to be evidence of an aquatic lifestyle; for example, broad claws are seen in most early tetrapods, even those that are known to have been almost exclusively terrestrial, and the long hindlimbs of Ophiacodon would not have been an effective means of propulsion because the feet were still relatively small and had little surface area over which to form a paddle. Analysis of the vertebrae of Ophiacodon indicate that it was most likely terrestrial and spent little time in water. A paleobiological inference model for the femur likewise suggests a terrestrial lifestyle for Ophiacodon, even though the rather thick cortex might also suggest amphibious, rather than truly terrestrial habits.

It was an effective means of propulsion under ideal conditions but otherwise had serious drawbacks. The paddle-wheel performed best when it operated at a certain depth, however when the depth of the ship changed from added weight it further submerged the paddle wheel causing a substantial decrease in performance.Carlton, 2012 p.23 Within a few decades of the development of the river and canal steamboat, the first steamships began to cross the Atlantic Ocean. The first sea-going steamboat was Richard Wright's first steamboat Experiment, an ex-French lugger; she steamed from Leeds to Yarmouth in July 1813.. The first iron steamship to go to sea was the 116-ton Aaron Manby, built in 1821 by Aaron Manby at the Horseley Ironworks, and became the first iron-built vessel to put to sea when she crossed the English Channel in 1822, arriving in Paris on 22 June. She carried passengers and freight to Paris in 1822 at an average speed of 8 knots (9 mph, 14 km/h).

Ox-powered Roman paddle wheel boat from a 15th-century copy of De Rebus Bellicis The use of a paddle wheel in navigation appears for the first time in the mechanical treatise of the Roman engineer Vitruvius (De architectura, X 9.5–7), where he describes multigeared paddle wheels working as a ship odometer. The first mention of paddle wheels as a means of propulsion comes from the fourth– or fifth-century military treatise De Rebus Bellicis (chapter XVII), where the anonymous Roman author describes an ox-driven paddle-wheel warship: A 15th-century paddlewheel boat powered by crankshafts (Anonymous of the Hussite Wars) Italian physician Guido da Vigevano (circa 1280–1349), planning for a new crusade, made illustrations for a paddle boat that was propelled by manually turned compound cranks. Paddle boat, by the Italian artist-engineer Taccola, De machinis (1449): The paddles wind a rope fixed to an anchor upstream, thus moving the boat against the current. One of the drawings of the Anonymous Author of the Hussite Wars shows a boat with a pair of paddlewheels at each end turned by men operating compound cranks.
