"I wanted for this intermeshing of the unhinged and the controlled to be reflected in the sound design too," said Bahnsen.
|
|
It uses a unique double-rotor system in which the two intermeshing rotors cross each other, eliminating the need for a tail rotor.
|
|
Nonlinear, with almost no character names or dialogue, the intermeshing narratives are organized instead by repeated images: a grassy landscape, a house of two or three stories, a sunlit window and versions of a dark-haired woman, whose tragedy forms the thread of a story.

|
Unmanned aerial vehicles with intermeshing rotors have also been flown.
|
|
Machines consist of a circle of 12 intermeshing screws that corotate around a static core.
|
|
They turn at the same angular velocity and this can be reinforced by intermeshing them as gear wheels.

The Kaman K-225, first flown in 1951, also used intermeshing rotors with servo-flap control and was the world's first helicopter to be powered by a gas turbine.

In 1947 Anton Flettner, a German aviation engineer, was brought to New York in the United States as part of Operation Paperclip. He was the developer of Germany's Flettner Fl 282 "Kolibri" (Hummingbird), a helicopter employing the "synchropter" principle of intermeshing rotors, a unique design principle that dispenses with the need for a tail rotor. Flettner settled in the US and became the chief designer of the Kaman company, where he designed new helicopters using the synchropter principle. The Huskie had an unusual intermeshing contra-rotating twin-rotor arrangement with control effected by servo-flaps.

Kaman K-Max, Missoula MT / 2010 HH-43 Huskie with intermeshing rotors Kaman K-MAX is optimized for external cargo load operations. Unmanned, remote control or optionally piloted variant Intermeshing rotors on a helicopter are a set of two rotors turning in opposite directions, with each rotor mast mounted with a slight angle to the other, in a transversely symmetrical manner, so that the blades intermesh without colliding. The arrangement allows the helicopter to function without a tail rotor, which saves power. However, neither rotor lifts directly vertically, which reduces efficiency per each rotor.

Mi-12 Transverse rotors are mounted on the end of wings or outriggers perpendicular to the body of the aircraft. Similar to tandem rotors and intermeshing rotors, the transverse rotor also uses differential collective pitch. But like the intermeshing rotors, the transverse rotors use the concept for changes in the roll attitude of the rotorcraft. This configuration is found on two of the first viable helicopters, the Focke-Wulf Fw 61 and the Focke-Achgelis Fa 223, as well as the world's largest helicopter ever built, the Mil Mi-12.

Kaman's first aircraft experience was working for Igor Sikorsky. In 1945, he started his own aircraft company, Kaman Aircraft, to pursue his own designs. In January 1947, the Kaman K-125 helicopter first flew. It utilized intermeshing rotors and Kaman's patented servo-flap rotor control.

HH-43 Huskie Intermeshing rotors on a helicopter are a set of two rotors turning in opposite directions with each rotor mast mounted on the helicopter with a slight angle to the other so that the blades intermesh without colliding. This configuration is sometimes referred to as a synchropter. Intermeshing rotors have high stability and powerful lifting capability. The arrangement was pioneered in Nazi Germany in 1939 with Anton Flettner's successful Flettner Fl 265 design, and later placed in limited production as the successful Flettner Fl 282 Kolibri, used by the German Kriegsmarine in small numbers (24 airframes produced) as an experimental light anti-submarine warfare helicopter.

Behind role suction, such forces as projective identification and countertransference have been singled out as operating at an unconscious level in the group.C. James/U. Connolly, Effective Change in Schools (2000) p. 53 Role lock – confirming mutual suction into complementary roles, such as victim and abuser – is ensured by the intermeshing of projective identifications.

It shows similar characteristics to Myrmecia, and somewhat resembles Oecophylla, commonly known as weaver ants. Workers are strictly nocturnal (active mainly at night) but navigate by vision, relying on large compound eyes. The mandibles are shorter than the head. They have 10 to 15 intermeshing teeth and are less specialised than those of Myrmecia and Prionomyrmex, being elongate and triangular.
|
|
In the mandible there are at least ten pairs of teeth, perhaps twelve. The back teeth are small, the front teeth are very long, robust and curved, pointing moderately forwards. At the front they form a large, intermeshing "prey grab", that may have been used to snatch fish from the water surface. The teeth of Angustinaripterus resemble those of Dorygnathus.

He did some extra fleshing-out of Jenny's history in the Jenny Sparks: The Secret History of the Authority limited series, focused on the origin stories of the members of the Authority. Most of Millar's additions are furthering Ellis's backstory and intermeshing Jenny Sparks with important historical figures of the 20th century, including Albert Einstein, Ernest Hemingway, Adolf Hitler, Jacques Cousteau, John Lennon, Princess Diana, and many others.

Coaxial rotors are two rotors mounted one above the other on the same axis. Intermeshing rotors are two rotors mounted close to each other at a sufficient angle to let the rotors intermesh over the top of the aircraft. Another configuration—found on tiltrotors and some early helicopters—is called transverse rotors, where a pair of rotors are mounted at each end of a wing-type structure or outrigger.

The K-125 was Charles Kaman's first helicopter, which utilized intermeshing rotors and Kaman's patented servo-flap stability control."Hall of Fame/Inventor Profile: Charles Kaman" The K-125 first flew on 15 January 1947. The K-190 and K-225 were an improved versions of the K-125, which first flew in April and July 1949 respectively. The U.S. Navy bought two and the Coast Guard one for $25,000 each.

In heavy-lift applications, the tandem rotor configuration was also used with some success, for example in the Boeing Chinook series. Other twin-rotor configurations, such as intermeshing, co-axial or side-by-side also saw some use. The autogyro, used significantly during the late 1930s and throughout the war, became relegated to private aviation and never saw wide acceptance. A Wallis example, "Little Nellie", became famous for its appearance in a James Bond film.

The design of the Abeille was directed by René Dorand at the helicopter division of SNCAC. An intermeshing rotor layout was chosen instead of a tail rotor design, following the examples of the 1939 Flettner Fl 265 and the Kellet XR-8 of 1944. Its twin, two blade rotors were driven by shafts which leaned out of the fuselage side-by-side. The rotor blades, which began some way from the hub, tapered strongly.
|
|
This configuration is sometimes referred to as a synchropter. Yaw is accomplished through varying torque, which is done by increasing collective pitch on one of the blade sets. Most intermeshing designs have two blades per mast, although exceptions such as the Kellett XR-10 with three blades per mast do exist. The arrangement was developed in Germany by Anton Flettner for a small anti-submarine warfare helicopter, the Flettner Fl 265 and later the Flettner Fl 282 Kolibri.

Though not having the form of a true rosette because the jaw ends were not expanded, the intermeshing front teeth functioned as a "prey grab" to catch slippery animals; the describers therefore consider Guidraco to have been a fish-eater. The neck vertebrae are moderately elongated, keeled and possess large pneumatic openings on their sides, the access by which the air sac of the neck could enter their hollow interiors. The axis bears a spiked spine.

The resulting aircraft had a stubby, egg-shaped fuselage with a single tail-fin and tricycle undercarriage. Two seats were enclosed side-by-side behind an extensively-glazed nose and the two rotors intermeshed with one another, offset by 12½°. The fuselage construction was of steel-tube, skinned in sheet metal and fabric, and the rotor blades were built of plywood ribs and skin attached to steel tubes. The intermeshing rotors quickly earned it the nickname "eggbeater".

Underway is "the intermeshing of different Latino subpopulations has laid the foundations for the emergence and ongoing evolution of a strong sense of latinidad" which establishes a "sense of cultural affinity and identity deeply rooted in what many Latinos perceive to be a shared historical, spiritual, aesthetic and linguistic heritage, and a growing sense of cultural affinity and solidarity in the social context of the United States." This unites Latinos as one, creating cultural kin with other Latino ethnicities.

While several nations experimented with contra-rotating propellers in aircraft, only the United Kingdom and Soviet Union produced them in large numbers. The U.S. worked with several prototypes, including the tail-sitting Convair XFY and Lockheed XFV "Pogo" VTOL fighters, but jet engine technology was advancing rapidly and the designs were deemed unnecessary. Some helicopters use contra-rotating coaxial rotors mounted one above the other. The H-43 Huskie helicopter uses non-coaxial intermeshing rotors turning in opposite directions.

There are two sub-types of twin screw extruders: co-rotating and counter-rotating. This nomenclature refers to the relative direction each screw spins compared to the other. In co-rotation mode, both screws spin either clockwise or counter clockwise; in counter- rotation, one screw spins clockwise while the other spins counter clockwise. It has been shown that, for a given cross sectional area and degree of overlap (intermeshing), axial velocity and degree of mixing is higher in co-rotating twin extruders.

During the Cold War the American Kaman Aircraft company produced the HH-43 Huskie, for USAF firefighting purposes. One example of the Kaman K-225 experimental synchropter was fitted with a small turboshaft engine in late 1951, becoming the world's first gas turbine-powered helicopter. Intermeshing rotored helicopters have high stability and powerful lifting capability. The latest Kaman K-MAX model is a dedicated sky crane design used for construction work, and has been modified for trials by the USMC as an optionally-unmanned cargo transporter.

In 1960–62 he was The Statesman's roving features editor, and 1962–68 the Sunday Magazine editor. In 1980–1986 he rose to be Deputy editor and became editor in 1986. A Hindu – though his mother is of the Brahmo Samaj — Datta-Ray had a Catholic wedding in Australia to a Bengali woman whom he met in Sydney. Datta-Ray sees himself as the product of the intermeshing of high- caste Bengali society and upper-class English society throughout the 18th and 19th centuries which, writes Datta-Ray, has now 'vanished'.

The inability to determine the precise cause of the intermeshing, combined with the fact that the "personal lifting device" concept was failing to live up to its expectations, led to the decision to terminate the project. Sundby was awarded the Distinguished Flying Cross for his test-flying work with the HZ-1, going on to test-fly the H-21 and H-34 helicopters, as well as seeing combat in the Vietnam War before retiring with the rank of colonel."Selmer A. Sundby". U.S. Army Aviation Museum website.

The YH-30 had a steel tube framework with a light metal skin, A single 200 hp Franklin piston engine was horizontally mounted amidships and powered two intermeshing tandem rotors. It had a fixed-wheel tricycle landing gear with a castering nosewheel. No civil or military orders were received and Jovanovich formed his own company, the Jovair Corporation, where he modified the MC-4C as a prototype for a four-seat private helicopter designated the Sedan 4E. The Sedan 4E was powered by 210 hp Franklin 6A-335 engine.

When closed it could be lowered for use as a landing flap or it could be split into alternating upper and lower sections, with intermeshing "fingers" for use in its intended role. It was very effective in this role, mainly due to its great surface area, but this was at the cost of the width of the ailerons, which significantly reduced their efficiency. A pair of fuel tanks were positioned in the roots of the center section. All fuel tanks were self sealing and the pilot and oil cooler were protected by of armor.

This helicopter, developed in 1938 with the support of Nazi Germany's Kriegsmarine, made it possible, for the first time, to transition from powered rotary-wing flight to autorotation and back again, making it the safest helicopter of its time. In contrast to the Fl 185, the Fl 265, believed to be the pioneering example of a synchropter, had two intermeshing rotors 12 m in diameter, powered by a 160 hp (119 kW) BMW-Bramo Sh 14 A radial engine in the nose of the fuselage, fitted with a fan to assist cooling. Six helicopters were constructed, but series production was curtailed in favour of the Flettner Fl 282.

Himmler had Flettner's wife and family escorted safely to Sweden for the duration of the war. Anton Flettner's partner and confidant was Dr. Kurt Hohenemser, a brilliant and thorough engineer who developed the details necessary for the success of Flettner's helicopters. Dr. Hohenemser's father was also Jewish, yet both remained unharmed during their tenure together throughout the war as they worked to develop the helicopter for military use. 300px While the final product, the Flettner Fl 282 Kolibri ("Hummingbird"), could be factory-assembled, Flettner and Hohenemser insisted that they were the only ones who were capable of assembling the complex intermeshing rotor gearbox assembly.

Instead of the four guide fingers in the American proposal, Syromyatnikov suggested three, and in lieu of hydraulic shock-absorbers, he proposed electromechanical attenuators. In essence, the Soviets had accepted the idea of using a set of intermeshing fingers to guide the two halves of the docking gear from the point of initial contact to capture. The concept of using shock absorbing attenuators on the active spacecraft's capture ring to buffer the impact of two spacecraft coming together was also acceptable. Both groups of engineers planned to retract the active half of the docking gear using an electrically powered winch to reel in a cable.

The Brat was a Chicano punk rock ensemble originating from the barrios of East Los Angeles, California. Its three core members consisted of lead singer Teresa Covarrubias, lead guitarist Rudy Medina, and alternate lead and rhythm guitarist Sidney Medina. From their conception in late 1978 to their eventual break-up in 1985, The Brat contributed to the customization and intermeshing of multiple musical and cultural models that culminated in the distinct East Los Angeles, Chican@ punk sound. Along with being pioneers in the East Los Angeles punk movement, they are best known for their five song EP Attitudes — released in 1980 through the independent label Fatima Records — while contributing to the understanding of the many ways culture transforms and challenges dominant hegemonic ideologies.

A pair of spring clamps, intended for use on automotive fuel lines Spring clamps are typically made from a strip of spring steel, cut so that one side has a narrow protrusion centered on the end, and the other side a pair of narrow protrusions on either side. The ends of these protrusions are then bent outwards, and the strip rolled to form a ring, with the protruding tabs intermeshing. To use the clamp, the exposed tabs are pressed towards each other (typically using pliers), increasing the diameter of the ring, and the clamp is slid onto the hose, past the portion that will go onto the barb. The hose is then fit onto the barb, the clamp expanded again, slid onto the portion of the hose over the barb, then released, compressing the hose onto the barb.

Cf., Huxley and Capa (1964) at 132. After having described (at 129–32) the series of attacks suffered by the Amahuaca, launched both by other tribes and by commercial interests (especially during the rubber boom), Huxley goes on to summarize the resulting, significant changes to the tribe's social structure: > "The Amahuaca diaspora that occurred within the past three centuries > transformed their original social organization (inadequate data hint that it > was structured upon subgroups and organized by villages) into deeply > suspicious, autarchic, single-family units—units quite independent of one > another economically and only intermeshing at a few points in their social > relationships." Córdoba is discussed in a 1991 book co-written by Luis Eduardo Luna, an anthropologist familiar with his Peruvian Amazon, and Pablo Amaringo, a local practitioner of native healing arts. Córdoba's singular familiarity with the plants of the tropical forest is highly praised, as well as his insights about ayahuasca and his chanting guidance of group sessions.
