Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

Nesmith Cougar
The Nesmith Cougar is a light aircraft that was developed in the United States in the 1950s and marketed for homebuilding. Development The design, by Robert Nesmith, is a conventional high-wing, strut-braced monoplane with fixed tailwheel undercarriage. The pilot and a single passenger were seated side by side. The fuselage and empennage were of welded steel-tube construction, while the wings were of wood, and the whole aircraft was fabric-covered. Some later aircraft were fitted with a tricycle undercarriage. The original Cougar design was marketed by Nesmith himself. His intent was to market a low-cost aircraft for homebuilders. He also used the aircraft as a troubled youth project to encourage teens to work together toward a goal. When a modified Cougar won an Experimental Aircraft Association (EAA) design competition in 1963, that organization took over selling plans. Rights to the design were eventually purchased by Acro Sport. The aircraft shape was influenced by the Beech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wittman Tailwind
The Wittman W-8 Tailwind is a popular two-seat light aircraft for homebuilding. It is a high-wing, braced cabin monoplane of taildragger configuration. It is constructed with a steel tubing fuselage, wood wings, and fabric covering. It offers exceptional cruising speeds and is economical to operate and maintain. Design and development The Tailwind is the third in a series of high-wing aircraft designed by Sylvester J. "Steve" Wittman (1904–1995), a well-known air racing pilot and race plane designer, who also played an important role in the emergence of homebuilt aircraft with the Wittman Tailwind and other designs in the United States. The first, the Wittman Buttercup two-seater, and later the Wittman Big X four-seater, which was bought by Cessna to use its spring steel landing gear. The Tailwind also inspired the last iteration, the O and O Special. A model of the 1965 Wittman Tailwind may be found in the Sun 'n Fun Museum. Wittman developed the C-85 powered "Flying Carp ...

Flaperon
A flaperon (a portmanteau of flap and aileron) on an aircraft's wing is a type of control surface that combines the functions of both flaps and ailerons. Some smaller kitplanes have flaperons for reasons of simplicity of manufacture, while some large commercial aircraft such as the Boeing 747, 767, 777, and 787 may have a flaperon between the flaps and aileron. The 787 has a configuration known as a SpoileFlaperon that combines the action of spoilers, flaps and ailerons into one control surface. Operation In addition to controlling the roll or bank of an aircraft, as do conventional ailerons, both flaperons can be lowered together to reduce stall speed, similarly to a set of flaps. On a plane with flaperons, the pilot still has the standard separate controls for ailerons and flaps, but the flap control also varies the flaperon's range of movement. A mechanical device called a "mixer" is used to combine the pilot's input into the flaperons. While the use of flaperons rather ...

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Bou ...

Rib (aircraft)
In an aircraft, ribs are forming elements of the structure of a wing, especially in traditional construction. By analogy with the anatomical definition of " rib", the ribs attach to the main spar, and by being repeated at frequent intervals, form a skeletal shape for the wing. Usually ribs incorporate the airfoil shape of the wing, and the skin adopts this shape when stretched over the ribs. Type of ribs There are several types of ribs. Form-ribs, plate-type ribs, truss ribs, closed-ribs, forged ribs and milled ribs, where form-ribs are used for light to medium loading and milled ribs offer the greatest strength. * Form-ribs are made from a sheet of metal bent into shape, such as a U-profile. This profile is placed on the skin, just like a stringer, but then in the other direction. * Plate-type ribs consist of sheet-metal, which has upturned edges and (often has) weight-saving holes cut into it. * Truss ribs are built up out of profiles that are joined together. These joints requ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Fabric Covering
Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as are the pioneering all-wood monocoque fuselages of certain World War I German aircraft like the LFG Roland C.II in its wrapped ''Wickelrumpf'' plywood strip and fabric covering. Early aircraft used organic materials such as cotton and cellulose nitrate dope; modern fabric-covered designs usually use synthetic materials such as Dacron and butyrate dope for adhesive. Modern methods are often used in the restoration of older types that were originally covered using traditional methods. Purpose/requirements The purposes of the fabric covering of an aircraft are: * To provide a light airproof skin for lifting and control surfaces. * To provide structural strength to otherwise weak structures. * To cover other non-lifting parts of an airc ...

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.
