Caudron C.570
The Caudron C.570 was a French twin-engine aircraft designed and built by Caudron in the mid-1930s. It was designed to function in multiple roles; as a bomber, passenger transport, paratroop aircraft, cargo aircraft and air ambulance. Design The Caudron C.570 was primarily designed to fill a gap in the types of aircraft available to French armed forces, that of a troop-carrier, though it could take on other roles. It was a low wing cantilever monoplane with wings in three parts, a span rectangular centre section and outer trapezoidal panels, ending in rounded tips. The wings were built around twin box spars made of spruce and plywood. The central section had an aluminium frame and light metal skin; the outer panels were ply-covered. Multi-section ailerons filled more than half the span of the outer panels' trailing edges. The C.570 had a square section fuselage. Its -long forward part, reaching aft to the wing trailing edges, housed the crew and up to eighteen troops and was ...

W Engine
A W engine is a type of piston engine where three or four cylinder banks use the same crankshaft, resembling the letter W when viewed from the front. W engines with three banks of cylinders are also called "broad arrow" engines, due to their shape resembling the British government broad arrow property mark. W engines are less common than V engines. Compared with a V engine, a W engine is typically shorter and wider. W3 engines One of the first W engines was the Anzani 3-cylinder, built in 1906, to be used in Anzani motorcycles. It is this W3 engine which also powered the 1909 Blériot XI, the first airplane to fly across the English Channel. The ''Feuling W3'' is a motorcycle engine that was built by an aftermarket parts company in the United States in the early 2000s. Like radial aircraft engines it has a master connecting rod and two slave rods connected to the pistons. W6 engines The Rumpler Tropfenwagen had a Siemens and Halske-built overhead valve W6 engine, with ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Servo Tabs
__NOTOC__ A servo tab is a small hinged device installed on an aircraft control surface to assist the movement of the control surfaces. Introduced by the German firm Flettner, servo tabs were formerly known as Flettner tabs. Servo tabs are not true servomechanisms, as they do not employ negative feedback to keep the control surfaces in a desired position; they only provide a mechanical advantage to the pilot. Servo tabs A servo tab, or balance tab, moves in the direction opposite to the desired movement of the control surface. It deflects airflow, generating force on the whole control surface in the desired direction. The tab has a leverage advantage, being located well aft of the control surface hinge line, and thus its airflow deflection moves the control surface in the opposite direction, overcoming the resistance generated by the airflow deflection of the control surface. This has the effect of reducing the control force required from the pilot to move the controls. In som ...

Flettner
Anton Flettner, Flugzeugbau GmbH was a German helicopter and autogyro manufacturer during World War II, founded by Anton Flettner. Flettner aircraft included: *Flettner Fl 184 - Reconnaissance autogyro, prototype *Flettner Fl 185 - Reconnaissance helicopter, prototype *Flettner Fl 265 - Reconnaissance helicopter, prototype *Flettner Fl 282 ''Kolibri'' (Hummingbird) - Reconnaissance helicopter *Flettner Fl 339 - Reconnaissance helicopter, project * Flettner Gigant - Experimental helicopter Anton Flettner's interest in aerodynamics (specifically the Magnus effect, which produces a force from a cylinder rotating in a fluid flow) also led him to invent the Flettner rotor which he used to power a Flettner ship which crossed the Atlantic, and the Flettner ventilator which is still widely used as a cooling device for buses, vans and other commercial vehicles and which is based upon the Savonius principle.

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ...

Endplate Fin
The spinal column, a defining synapomorphy shared by nearly all vertebrates, Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the backbone), and on the other with phylogenetic differences among the vertebrate taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Elevator (aeronautics)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and ...

Tailplane
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Twin Tail
A twin tail is a specific type of vertical stabilizer arrangement found on the empennage of some aircraft. Two vertical stabilizers—often smaller on their own than a single conventional tail would be—are mounted at the outside of the aircraft's horizontal stabilizer. This arrangement is also known as an H-tail,Schiff, Barry: ''Flying'', page 15. Golden Press, New York, 1971. Library of Congress 78-103424 as it resembles a capital "H" when viewed from the rear. The twin tail was used on a wide variety of World War II multi-engine designs that saw mass production, especially on the American B-24 Liberator and B-25 Mitchell bombers, the British Avro Lancaster and Handley Page Halifax heavy bombers, and the Soviet Union's Petlyakov Pe-2 attack bomber. Variations on the twin tail include the triple tail, twin boom tail and double tail. Design Separating the control surfaces allows for additional rudder area or vertical surface without requiring a massive single tail. On m ...

Oleo Strut
An oleo strut is a pneumatic air–oil hydraulic shock absorber used on the landing gear of most large aircraft and many smaller ones. This design cushions the impacts of landing and damps out vertical oscillations. It is undesirable for an airplane to bounce on landing as it could lead to a loss of control, and the landing gear should not add to this tendency. A steel coil spring stores impact energy from landing and then releases it, while an oleo strut instead absorbs this energy, reducing bounce. As the strut compresses, the spring rate increases dramatically because the air is being compressed. The viscosity of the oil dampens the rebound movement. History and applications The original design for the oleo-pneumatic shock-absorbing strut was patented by British manufacturing conglomerate Vickers Armstrong during 1915. It had been derived from the recuperative gear design of the Vickers gun, controlling recoil by forcing oil through precisely sized orifices. Vickers' oleo stru ...
