Abrial A-13 Buse
The Abrial A-13 Buse was a tailless glider prototype that was designed in 1954. It was the last in a series of glider aircraft designed by Georges Abrial. Design The glider featured a short fuselage with a single, non-tapered strut-braced straight wing. The design had been demonstrated by very complete tests carried out on a 1:10 scale model at the Eiffel Laboratory but no full-size version was ever constructed.

Glider (sailplane)
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and eithe ...

Georges Abrial
Georges Abrial (1898 in Paris – 1970 in Vauville, Manche) was an early France, French aerodynamics, aerodynamicist. Life After graduating from the St Cyr Aeronautical Institute he worked for Pierre Levasseur (aircraft builder), Levasseur (Levasseur-Abrial A-1) and did some pioneering work into tailless aircraft. He designed several Glider aircraft, gliders during the 1920s before turning to lecturing the following decade, when he also became influential in the French Lift (soaring), soaring movement. Abrial stopped designing new aircraft after 1932 when he abandoned his A-12 project. He was more attracted by instructorship and educational methods and played an important role in the development of soaring in France during the 1930s. After World War II, he was still active in promoting soaring in France and in French Africa. In 1954 he came back to the design of tailless aircraft, with the A-13 "Buse" project. But this glider was never built. Aircraft designs *Abrial A-2 Vautour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye.

Strut-braced
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more impo ...

Abrial A-2 Vautour
The A-2 ''Vautour'' (''Vulture'') was a single-seat French glider that was designed by Georges Abrial. It performed well at the Vauville competition of 1925. Design The Vautour was designed by Georges Abrial of the ''Institut Aérotechnique de Saint-Cyr'' and built by Louis Peyret. Each wing, joined to a centre-section on top of the fuselage with light dihedral, had a rectangular plan apart from an angled tip and carried a broad chord aileron which filled about 60% of the span. They were of mixed construction with two rectangular section dural spars and plywood ribs. Each wing was braced with a pair of parallel struts, dural tubes enclosed in streamlined, wooden fairings, between the lower fuselage longerons and the wing spars just inside the ailerons. Its fuselage was rectangular in section, with spruce longerons and laminated wood frames. The sides were everywhere vertical but ahead of the wing it narrowed in plan and decreased in depth to a rounded nose. The downward s ...

Abrial A-12 Bagoas
__NOTOC__ The A-12 was an unusual tailless glider designed by Georges Abrial in the early 1930s. It was not a success and was abandoned in 1932. Design The Abrial A-12 was unusual in having a very low aspect ratio wing, even by the standards of its time. Other tailless gliders of the 1920s, notably the Lippisch Storch series had aspect ratios of about 8, compared with the 4.75 of the Abrial. Further, where the Storchs had swept wings the Abrial's was rectangular in plan. After encouraging tests of models in the wind tunnel at St Cyr, Abrial built a full-sized version. The Abrial's wings had the designer's own reflexed camber aerofoil. Such aerofoils are useful for tailless aircraft, because the pitching moment about the aerodynamic centre of the wing can be zero. The wings were mounted with strong dihedral and braced from above by a V-strut on each side, their apexes meeting at a faired triangular central support structure. It had control surfaces on the wings which may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood gliders. Etym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
