Thomas-Morse XP-13 Viper
The XP-13 Viper was a prototype biplane fighter aircraft designed by the United States, American company Thomas-Morse Aircraft Corporation. The airplane was delivered to the United States Army in 1929, but they did not adopt it. Design and development This aircraft was one of several B. Douglas Thomas designs built in hopes of a production contract from the Army, following the successful Thomas-Morse MB-3 of 1919. Financed by the company, and named the "Viper", it was officially purchased by the Army in June 1929 and designated "XP-13". The XP-13 fuselage had a corrugated aluminum skin built over a metal frame; the flying surfaces were also metal-framed, but covered with the traditional fabric.

A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Pratt & Whitney R-1340
The Pratt & Whitney R-1340 Wasp is an aircraft engine of the reciprocating engine, reciprocating type that was widely used in United States, American aircraft from the 1920s onward. It was the Pratt & Whitney aircraft company's first engine, and the first of the famed Pratt & Whitney Wasp series, Wasp series. It was a single-row, nine-cylinder (engine), cylinder, air-cooled engine, air-cooled, radial engine, radial design, and engine displacement, displaced 1,344 cubic inches (22 L); bore and stroke were both 5.75 in (146 mm). A total of 34,966 engines were produced. As well as numerous types of fixed-wing aircraft, it was used to power helicopters, the Agusta-Bell AB.102 and the Sikorsky H-19, and a class of airship, the K-class blimp. In 2016, it received designation as a List of Historic Mechanical Engineering Landmarks, Historic Engineering Landmark from the ASME, American Society of Mechanical Engineers.

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag (aerodynamics), drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. ...

Bill Gunston
Bill Gunston (1 March 1927 – 1 June 2013) was a British aviation and military author. He flew with Britain's Royal Air Force from 1945 to 1948, and after pilot training became a flying instructor. He spent most of his adult life doing research and writing on aircraft and aviation. He was the author of over 350 books and articles. His work included many books published by Salamander Books.

List Of Fighter Aircraft
Fighter aircraft are military aircraft primarily designed for Aerial warfare, air-to-air combat. They usually carry various weapons and missiles intended for air strikes and are used to achieve air superiority, superiority over airspaces. While these aircraft are meant for aerial warfare, and does not include aircraft used for specific roles such as List of attack aircraft, ground attack aircraft, List of bomber aircraft, bombers and Trainer aircraft, trainers, there is some overlap in roles and designs. Multirole combat aircraft are utlized for various roles and fall under multiple categories. The key performance features of a fighter apart from its firepower include its high speed and maneuverability. Fighter aircraft are sorted into Jet fighter generations, generations, from one to five, based on technological level and advancements. The fighter aircraft are often designated by a specific naming convention based on the country of origin. The name usually consists of a letter p ...

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, 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 ar ...

Curtiss Aeroplane And Motor Company
The Curtiss Aeroplane and Motor Company (1909–1929) was an American aircraft manufacturer originally founded by Glenn Curtiss, Glenn Hammond Curtiss and Augustus Moore Herring in Hammondsport, New York. After significant commercial success in its first decades, it merged with the Wright Aeronautical to form Curtiss-Wright Corporation. History Origin In 1907, Glenn Curtiss was recruited by the scientist Dr. Alexander Graham Bell as a founding member of Bell's Aerial Experiment Association (AEA), with the intent of establishing an aeronautical research and development organization. According to Bell, it was a "co-operative scientific association, not for gain but for the love of the art and doing what we can to help one another."Milberry 1979, p 13. In 1909, shortly before the AEA was disbanded, Curtiss partnered with Augustus Moore Herring to form the Herring-Curtiss Company.Gunston 1993, p. 87. It was renamed the Curtiss Aeroplane Company in 1910 and reorganized in 1912 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, 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 or fuselage, thus imparting a turning or 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 afterend. Often rudders are shaped to minimize 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 link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics. H ...
