Parasol Wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of 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 can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Supermarine Spitfire
The Supermarine Spitfire is a British single-seat fighter aircraft used by the Royal Air Force and other Allied countries before, during, and after World War II. Many variants of the Spitfire were built, from the Mk 1 to the Rolls-Royce Griffon engined Mk 24 using several wing configurations and guns. It was the only British fighter produced continuously throughout the war. The Spitfire remains popular among enthusiasts; around 70 remain airworthy, and many more are static exhibits in aviation museums throughout the world. The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell developed the Spitfire's distinctive elliptical wing with innovative sunken rivets (designed by Beverley Shenstone) to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary ...

Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a d ...

Consolidated PBY Catalina
The Consolidated PBY Catalina is a flying boat and amphibious aircraft that was produced in the 1930s and 1940s. In Canadian service it was known as the Canso. It was one of the most widely used seaplanes of World War II. Catalinas served with every branch of the United States Armed Forces and in the air forces and navies of many other nations. The last military PBYs served until the 1980s. As of 2021, 86 years after its first flight, the aircraft continues to fly as a waterbomber (or airtanker) in aerial firefighting operations in some parts of the world. None remain in military service. Design and development Background The PBY was originally designed to be a patrol bomber, an aircraft with a long operational range intended to locate and attack enemy transport ships at sea in order to disrupt enemy supply lines. With a mind to a potential conflict in the Pacific Ocean, where troops would require resupply over great distances, the U.S. Navy in the 1930s invested million ...

Dornier Do 18
The Dornier Do 18 was a development of the Do 16 flying boat. It was developed for the ''Luftwaffe'', but ''Luft Hansa'' received five aircraft and used these for tests between the Azores and the North American continent in 1936 and on their mail route over the South Atlantic from 1937 to 1939. On 27–29 March 1938, a "Do 18 W" established a seaplane record, flying non-stop a straight distance of 8,391 km (5,214 mi) from Start Point, Devon to Caravelas in Brazil. Design and development In 1934, the Dornier ''Flugzeugwerke'' started development of a new twin-engine flying boat to replace the Dornier Do J ''"Wal"'' (Whale) in both military and civil roles. The resultant design, ''Do 18'', retained the layout of the Wal, with a metal hull fitted with distinctive stabilising sponsons, and powered by two engines above the wing in a push-pull layout, but was aerodynamically and hydrodynamically more efficient. It was planned to be powered by two of the new Junkers Jumo 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin M-130
The Martin M-130 was a commercial flying boat designed and built in 1935 by the Glenn L. Martin Company in Baltimore, Maryland, for Pan American Airways. Three were built: the '' China Clipper'', the ''Philippine Clipper'' and the '' Hawaii Clipper''. All three had crashed by 1945. A similar flying boat, (the Martin 156), named ''Russian Clipper'', built for the Soviet Union, had a larger wing (giving it greater range) and twin vertical stabilizers. Martin named them the Martin Ocean Transports, but to the public they were the "China Clippers", a name that became a generic term for Pan Am's large flying boats - including, retroactively, the smaller Sikorsky S-42 (first flown in 1931) and larger Boeing 314 (first flown in 1938).

Morane-Saulnier AI
The Morane-Saulnier AI (also Type AI) was a French parasol-wing fighter aircraft produced by Morane-Saulnier during World War I. Development and design The AI was developed as a refinement of the Morane-Saulnier Type N concept, and was intended to replace the Nieuport 17 and SPAD VII in French service, in competition with the SPAD XIII, which it was built as a back-up for. Its Gnome Monosoupape ''9N'' 160 CV rotary engine was mounted in a circular open-front cowling. The strut braced parasol wing was swept back. The spars and ribs of the circular section fuselage were wood, wire-braced and covered in fabric, and faired out with wood stringers. The production aircraft were given service designations based on whether they had 1 Vickers machine gun (designated ''MoS 27'') or 2 Vickers guns (designated ''MoS 29'').Donald 1997, p. 659. Operational history A number of escadrilles were created to operate the AI, but by mid-May 1918, most of the aircraft were replaced by the SPAD XIII ...

Fokker D
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912. World War I Fokker capitalized o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morane-Saulnier L
The Morane-Saulnier L, or Morane-Saulnier Type L, or officially MoS-3, was a French parasol wing one or two-seat scout aeroplane of the First World War. The Type L became one of the first successful fighter aircraft when it was fitted with a single machine gun that fired through the arc of the propeller, which was protected by armoured deflector wedges. Its immediate effectiveness in this role launched an arms race in fighter development, and the Type L was swiftly rendered obsolete. The original Type L used wing warping for lateral control, but a later version designated Type LA was fitted with ailerons.Taylor 1989, p. 684. Built by Morane-Saulnier, large numbers of the Type L were ordered by the French ''Aviation Militaire'' at the outbreak of the war. In total about 600 Type Ls were built and, in addition to the French air force, they served with the Royal Flying Corps, Royal Naval Air Service and the Imperial Russian Air Service. The type was also produced under licence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cessna 152
The Cessna 152 is an American two-seat, fixed- tricycle-gear, general aviation airplane, used primarily for flight training and personal use. It was based on the earlier Cessna 150 incorporating a number of minor design changes and a slightly more powerful engine with a longer time between overhaul. The Cessna 152 has been out of production for almost forty years, but many are still airworthy and are in regular use for flight training. Development First delivered in 1977 as the 1978 model year, the 152 was a modernization of the proven Cessna 150 design. The 152 was intended to compete with the new Beechcraft Skipper and Piper Tomahawk, both of which were introduced the same year. Additional design goals were to improve useful load through a gross weight increase to , decrease internal and external noise levels and run better on the then newly introduced 100LL fuel.. As with the 150, the great majority of 152s were built at the Cessna factory in Wichita, Kansas. A number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barber Snark
The Barber Snark is a two-seater kit-plane, designed and built in New Zealand by Bill Barber. It first flew in late 1987. Only some five aircraft have been built. Design and development The Snark is a tricycle aircraft of composite construction. Its glider-like cockpit accommodates a pilot and passenger in tandem, the passenger sitting behind and higher than the pilot. The centrally mounted shoulder-wing lies behind the pilot, who has unrestricted visibility. The Suzuki engine is sited behind the cockpit, driving a pusher propeller. Wing control surfaces on the third Snark were flaperons, while the fourth aircraft had conventional ailerons and flaps. Above the propeller, and aft of the cockpit is a slender boom to the empennage comprising a T-tail with a high-mounted tailplane. The Snark's tandem layout, its small frontal area, and its low wetted area The surface area that interacts with the working fluid or gas. In maritime industry, maritime use, the wetted area ...
