Aircraft Research BT-11
The Aircraft Research XBT-11 was to have been a basic trainer constructed by the Aircraft Research Corporation (formerly the Vidal Research Corporation) of Bendix, New Jersey, by molding "Weldwood", a "plastic" plywood composite material made of heat and pressure-processed phenol phenol-formaldehyde resins and wood similar to the Duramold process. The Duramold and Haskelite Haskelite is the brand name of a plywood, once made by the Michigan-based Haskelite Manufacturing Corporation. It was made from waterproof glue developed by Henry L. Haskell. The moldable plywood was originally called Ser-O-Ply. It was used in ... processes were first developed in 1937, followed by Eugene L. Vidal's Weldwood in 1938.

An aircraft is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or by using the Lift (force), dynamic lift of an airfoil, or in a few cases the Powered lift, downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers.

United States Army Air Corps
The United States Army Air Corps (USAAC) was the aerial warfare service component of the United States Army between 1926 and 1941. After World War I, as early aviation became an increasingly important part of modern warfare, a philosophical rift developed between more traditional ground-based army personnel and those who felt that aircraft were being underutilized and that air operations were being stifled for political reasons unrelated to their effectiveness. The USAAC was renamed from the earlier United States Army Air Service on 2 July 1926, and was part of the larger United States Army. The Air Corps became the United States Army Air Forces (USAAF) on 20 June 1941, giving it greater autonomy from the Army's middle-level command structure. During World War II, although not an administrative echelon, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the Department of the Air Force.

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] |
Duramold
Duramold is a composite material process developed by Virginius E. Clark. Birch or Populus, poplar plies are impregnated with phenolic resin and laminated together in a mold under heat (280 °F, 138 °C) and pressure for use as a lightweight structural material. Similar to plywood, Duramold and other lightweight composite materials like the similar Haskelite were considered critical during periods of material shortage in World War II, replacing scarce materials like aluminum alloys and steel.Dana T. Parker, ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II'', Cypress, CA, 2013, , pp. 51-52, 56. . The material has some advantages over metal in strength, construction technique, and weight. A cylinder made of Duramold is 80% stronger than a cylinder made of aluminum. Over 17 varieties of Duramold were developed, using various combinations of types of wood in thin plies. The Duramold process has also been used to make radomes for aircraft as ...

Haskelite
Haskelite is the brand name of a plywood, once made by the Michigan-based Haskelite Manufacturing Corporation. It was made from waterproof glue developed by Henry L. Haskell. The moldable plywood was originally called Ser-O-Ply. It was used in the construction of various vehicles including military tanks, boats, airplanes, buses, trucks, and automobiles. The plywood was manufactured with different characteristics depending on particular needs and then given a brand name. Background Haskell invented a process for making a waterproof glue called "black albumin glue" from blood-albumin which was used to bond wood including a lightweight waterproof plywood which was initially known as Ser-O-Ply. The plywood was used for boats, airplanes, tanks, trucks, automobiles and rail cars. The plywood panels had various layers of crossed-grain ply veneers to create the thickness and strength. Typical moldable plywood panels were about wide by long and thick. The sheets made this way w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eugene Luther Vidal
Eugene Luther "Gene" Vidal (; April 13, 1895 – February 20, 1969) was an American commercial aviation pioneer, New Deal official, inventor, and athlete. He was the father of author Gore Vidal. For eight years, from 1929 to 1937, he worked closely with Amelia Earhart in a number of aviation-related enterprises, and was President Franklin Roosevelt's top civil aviation director from 1933 to 1937. In his obituary, ''Time'' noted: "Eugene Vidal, 73, pioneer promoter of civil aviation and father of author Gore Vidal; in Los Angeles, Calif. Vidal starred in football at West Point and competed in the decathlon in the Antwerp Olympic Games of 1920. He later taught aviation and coached football at the academy, resigned his commission in 1926 to become assistant general manager of Transcontinental Air Transport (later TWA)." From September 1933 to March 1937 he was Director of the Bureau of Air Commerce (a predecessor of the Federal Aviation Administration) in Washington, where h ...

James Charles Fahey
James Charles Fahey (1903–1974) was an American writer best remembered as the original compiler and publisher of the popular American reference ''The Ships and Aircraft of the United States Fleet''. ''The Ships and Aircraft of the United States Fleet'' James Fahey lived in the Bronx working as a cab driver and merchant marine sailor while he wrote for various publications on the subject of military ships and aircraft. His disappointment at editors "butchering" his manuscripts caused him to self-publish the first edition of ''Ships and Aircraft of the United States Fleet'' in 1939. He carefully compiled data from unclassified sources and had a unique talent for presenting a great deal of information in compact, tabular format. His softbound 48-page booklet sold for fifty cents, and gained public interest as World War II unfolded. An updated second edition (the '' Two Ocean Fleet Edition'') was published in the same 48-page format in 1941,Fahey, James C. ''The Ships and Aircraft ...

Pratt & Whitney R-985-25
The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a displacement of ; initial versions produced , while the most widely used versions produce . Wasp Juniors have powered numerous smaller civil and military aircraft, including small transports, utility aircraft, trainers, agricultural aircraft, and helicopters. Over 39,000 engines were built, and many are still in service today. Design and development Pratt & Whitney developed the R-985 Wasp Junior as a smaller version of the R-1340 Wasp to compete in the market for medium-sized aircraft engines. Like its larger brother, the Wasp Junior was an air-cooled, nine-cylinder radial, with its power boosted by a gear-driven single-speed centrifugal type supercharger. Its cylinders were smaller, however, with a bore and stroke of , giving a 27% lesser total displacement. The Wasp Junior used ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Timm PT-160
The Timm N2T Tutor is an American training monoplane built by the Timm Aircraft Corporation for the United States Navy as the N2T-1. Design and development The Timm S-160 (or Timm PT-160K) was a conventional tandem open-cockpit monoplane trainer first flown on the 22 May 1940 by test pilot Vance Breese. It was powered by a Kinner R-5 radial engine and was a low-wing cantilever monoplane with a tailwheel landing gear. It had an unusual feature in that the airframe structure was made from resin impregnated and molded plywood, creating a composite material stronger and lighter than plywood. This process was patented as the Nuyon process and marketed as the aeromold process. The S-160 received the first approval for a plastic-wood construction, (ATC #747), on 28 August 1941. The PT-175-K variant was fitted with a Kinner R-53 engine. This was followed by the PT-220-C with a 220 hp (164 kW) Continental W-670-6 engine and larger tail. Operational history The PT-220C was ...
