Structural Skin
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which ...

Deperdussin Monocoque (MAE)
The Deperdussin Monocoque was an early racing aircraft built in 1912 by the Aéroplanes Deperdussin, a French aircraft manufacturer started in 1911 and reorganized as the Société Pour L'Aviation et ses Dérivés ( SPAD) in 1913. It is so named because of the method of construction of its fuselage. The aircraft is noted for winning the Gordon Bennett Trophy in 1912 and 1913, and for raising the world speed record for aircraft to . Background The first use of monocoque construction in aviation is attributed to Eugene Ruchonnet, a Swiss marine engineer who had built an aircraft nicknamed the ''Cigare'' in 1911, which had a fuselage constructed by building up several layers of thin wood, each lamination being applied at right angle to the one underneath. The usual method of construction of an aircraft's fuselage at this time was to use a wire braced box-girder covered in fabric. Ruchonnet's technique, in which the outer surface of the structure is load-bearing, would become the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pfalz Flugzeugwerke
Pfalz Flugzeugwerke was a World War I German aircraft manufacturer, located at the Speyer airfield in the Palatinate (German: Pfalz). They are best known for their series of fighters, notably the Pfalz D.III and Pfalz D.XII. The company went bankrupt after the Armistice, when the French occupation forces confiscated all of the equipment, but the factory was re-used by various other companies until re-forming in 1997. Today they are a parts manufacturer referred to as PFW. Early history Pfalz was the brainchild of Alfred Eversbusch, son of a foundry owner in Neustadt an der Weinstraße. It appears that he had built his own aircraft between 1912 and 1913, although the exact origin of the design is unclear. On June 3, 1913, the Pfalz company was registered, consisting of Alfred, his brother Ernst, and his brother-in-law Willy Sabersky-Müssigbrodt, as well as several investors: Richard and Eugen Kahn, and August Kahn (unrelated). They initially proposed to build designs from Al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chassis
A chassis (, ; plural ''chassis'' from French châssis ) is the load-bearing framework of an artificial object, which structurally supports the object in its construction and function. An example of a chassis is a vehicle frame, the underpart of a motor vehicle, on which the body is mounted; if the running gear such as wheels and transmission, and sometimes even the driver's seat, are included, then the assembly is described as a rolling chassis. Examples of use Vehicles In the case of vehicles, the term ''rolling chassis'' means the frame plus the "running gear" like engine, transmission, drive shaft, differential and suspension. An underbody (sometimes referred to as " coachwork"), which is usually not necessary for integrity of the structure, is built on the chassis to complete the vehicle. For commercial vehicles, a rolling chassis consists of an assembly of all the essential parts of a truck without the body to be ready for operation on the road. A car chassi ...

Aluminum Alloy
An aluminium alloy (or aluminum alloy; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', Arnold, 1995 Alloys ...

McLaren MP4
The McLaren MP4/1 (initially known as the MP4) was a Formula One racing car produced by the McLaren team. It was used during the 1981, 1982 and 1983 seasons. It was the second Formula One car to use a monocoque chassis wholly manufactured from carbon fibre composite, after the Lotus 88 (which never raced), a concept which is now ubiquitous. The MP4/1 was first entered in a Formula One race at the third grand prix of the season in Argentina. The chassis was designed by John Barnard, Steve Nichols and Alan Jenkins, with the car being powered by a Cosworth DFY engine. The MP4 was the first car to be built following the merger of the McLaren team and Ron Dennis' Project 4 Formula 2 team; its designation was short for "Marlboro Project 4". Design and construction The main engineer for the MP4 was John Barnard, who began drawing the car in late 1979. After a visit to the Rolls-Royce factory where he saw engineers working with carbon fibre technology on the Rolls-Royce RB211 jet ...

Northrop Alpha
The Northrop Alpha was an American single-engine, all-metal, seven-seat, low-wing monoplane fast mail/passenger transport aircraft used in the 1930s. Design work was done at the Avion Corporation, which in 1929, became the Northrop Aircraft Corporation based in Burbank, California. Design and development Drawing on his experience with the Lockheed Vega, John K. Northrop designed an advanced mail/passenger transport aircraft. In addition to all-metal construction, the new Alpha benefitted from two revolutionary aerodynamic advancements: wing fillets researched at the Guggenheim Aeronautical Laboratory at the California Institute of Technology, and a multicellular stressed-skin wing of Northrop's own design which was later successfully used on the Douglas DC-2 and Douglas DC-3. In addition, the Alpha was the first commercial aircraft to use rubber deicer boots on wing and empennage leading edges which, in conjunction with state-of-the-art radio navigation equipment, gave it day o ...

Short Silver Streak
The Short Silver Streak was the first British all-metal aircraft.Jackson 1973, p. 297. It was designed and built by Short Brothers at Rochester, Kent, England. Although ''Flight'' magazine claimed that it was the first instance of stressed skin construction in the world, it was preceded by a number of Dornier designs, including the Dornier-Zeppelin D.I, which was ordered into production. Development The Silver Streak was a single-seat biplane with a semi-monocoque duralumin fuselage and duralumin-covered wings. The wing skin was not stressed. The Silver Streak had a conventional landing gear and was powered by a Siddeley Puma engine. The Silver Streak was exhibited in July 1920 at the Olympia in London. Registered G-EARQ, it was first flown at Grain on 20 August 1920 by test pilot J. L. Parker. It was later modified as a two-seater and delivered to the Air Ministry in February 1921 for both flight and static testing. The Air Ministry issued a specification for a two-seat rec ...

Oswald Short
Hugh Oswald Short, AFRAeS (16 January 1883 – 4 December 1969) was an English aeronautical engineer. Early life Oswald Short was born at Stanton by Dale, Ilkeston, Derbyshire, the son of mining engineer Samuel Short and his second wife Emma Robinson. In 1897, he took an intense interest in ballooning, after his brother Eustace Short (1875 – 1932) had purchased, repaired and flown a second-hand gas balloon. The two brothers formed a partnership to design and manufacture balloons for fairground businesses, and made a joint visit to the 1900 Paris Exposition ('World's Fair'). There, they were inspired by the perfectly spherical balloons made by Édouard Surcouf of Société Astra, and they then modified their own design accordingly. In 1901, the two brothers constructed their first balloon, capacity 33,000 cu.ft, in premises above the laboratory of their brother Horace Short (2 July 1872 – 6 April 1917), in Hove, Sussex. In 1902, the balloon made successful flights, and in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeppelin-Lindau Rs
Luftschiffbau Zeppelin GmbH is a German aircraft manufacturing company. It is perhaps best known for its leading role in the design and manufacture of rigid airships, commonly referred to as ''Zeppelins'' due to the company's prominence. The name 'Luftschiffbau' is a German word meaning ''building of airships''. The company was founded by Count Ferdinand von Zeppelin in 1908 as a formal entity to continue advancing his pioneering research into rigid airships. ''Luftschiffbau Zeppelin'' became the leading manufacturer in the field of large lighter-than-air vehicles; its products were used in both military and civilian capacities. The firm founded DELAG, the world's first airline to use an aircraft in revenue service, in 1909 on the back of public interest and using its own airships. During the First World War, Zeppelins were employed as the first long distance strategic bombers, launching numerous raids upon Belgium, France, and the United Kingdom. Following Count von Zeppelin's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeppelin-Staaken E-4/20
The Zeppelin-Staaken E-4/20 was a revolutionary four-engine all-metal passenger monoplane designed in 1917 by Adolf Rohrbach and completed in 1919 at the Zeppelin-Staaken works outside Berlin, Germany. The E-4/20 was the first four-engine, all-metal stressed skin heavier-than-air airliner built. Design and development At a time when most aircraft were small, single-engine biplanes made of wood and canvas, the E-4 was a large (102-foot wingspan), all-metal, four-engine, stress-skinned, semi-monocoque, cantilevered-wing monoplane, with an enclosed cockpit, and accommodation for 18 passengers plus a crew of five, including two pilots, a radio operator, an engineer and a steward, as well as radio-telegraph communications, a toilet, a galley and separate baggage and mail storage. With a maximum speed of 143 mph, cruising speed of , a range of about , and a fully loaded weight of , it outperformed most other airliners of its day. The E-4 included numerous innovations, includi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rohrbach Metall-Flugzeugbau
Rohrbach Metall-Flugzeugbau was an airplane factory located in Berlin, Germany and founded in 1922 by Dr.-Ing Adolf Rohrbach. Rohrbach was a pioneer in building airplanes based on the metal stressed skin principle. At the time of the early aircraft production the Versailles Treaty forbade the construction and export of large aircraft in Germany, so Rohrbach set up a Danish company, the 'Rohrbach-Metall-Aeroplan Co. A/S', to build the early Rohrbach aircraft. The strict regulation of the aircraft industry was relaxed in 1926 allowing the Rohrbach series to be built at the Rohrbach Metall-Flugzeugbau GmbH factory in Berlin. The company enjoyed only limited commercial success, with the Rohrbach Roland ten-seat airliner as its only model built in any quantity. By 1934 the company was taken over by Weser Flugzeugbau, where Adolf Rohrbach became technical director.
