Monocoque
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 whi ...

Deperdussin Monocoque (MAE)
The Deperdussin Monocoque was an early racing aircraft built in 1912 by the Société Pour les Appareils Deperdussin, Aéroplanes Deperdussin, a French aircraft manufacturer started in 1911 and reorganized as the Société Pour L'Aviation et ses Dérivés (Société Pour L'Aviation et ses Dérivés, SPAD) in 1913. It is so named because of the monocoque, method of construction of its fuselage. The aircraft is noted for winning the Gordon Bennett Trophy (aeroplanes), Gordon Bennett Trophy in 1912 and 1913, and for raising the world speed record for aircraft to . Background The usual method of construction of an aircraft's fuselage at this time was to use a wire braced box-girder covered in fabric. 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 applied at right angle ...

Semi-monocoque
The term semi-monocoque or semimonocoque refers to a stressed shell structure that is similar to a true monocoque, but which derives at least some of its strength from conventional reinforcement. Semi-monocoque construction is used for, among other things, aircraft fuselages, car bodies and motorcycle frames. Examples of semi-monocoque vehicles Semi-monocoque aircraft fuselages differ from true monocoque construction through being reinforced with longitudinal stringers. The Mooney Aviation Company, Mooney range of four seat aircraft, for instance, use a steel tube truss frame around the passenger compartment with monocoque behind. The British ARV Super2 light aircraft has a fuselage constructed mainly of aluminium alloy, but with some fibreglass elements. The cockpit is a stiff monocoque of "Supral" alloy, but aft of the cockpit bulkhead, the ARV is conventionally built, with frames, longerons and stressed skin forming a semi-monocoque."Pilot" magazine, June 1985 pages 5-6 ...

Chassis
A chassis (, ; plural ''chassis'' from French châssis ) is the load-bearing framework of a manufactured 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 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. The "rolling chassis" description originated from assembly production when an integrated chassis "rolled on its own tires" just before truck bodies were bolted to the frames near the end of the line. An underbody (sometimes referred to as " coachwork"), which is usually not necessary for the integrity of the structure, is built on the chassis to c ...

Stressed Skin
In mechanical engineering, stressed skin is a rigid construction in which the skin or covering takes a portion of the structural load, intermediate between monocoque, in which the skin assumes all or most of the load, and a rigid frame, which has a non-loaded covering. Typically, the main frame has a rectangular structure and is Polygon triangulation, triangulated by the covering; a stressed skin structure has localized compression (physical), compression-taking elements (rectangular frame) and distributed tension (physics), tension-taking elements (skin). Description A simple framework box with four discrete members is not inherently rigid as it will distort from being square under relatively light loads; however, adding one or more diagonal element(s) that take either tension or compression makes it rigid, because the box cannot deviate from right angles without also altering the diagonals. Sometimes the diagonal elements are flexible like wires, which are used to provide te ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Vehicle Frame
A vehicle frame, also historically known as its ''chassis'', is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism. Until the 1930s, virtually every car had a structural frame separate from its body, known as ''body-on-frame'' construction. Both mass production of completed vehicles by a manufacturer using this method, epitomized by the Ford Model T, and supply of rolling chassis to coachbuilders for both mass production (as by Fisher Body in the United States) and to smaller firms (such as Hooper (coachbuilder), Hooper) for bespoke bodies and interiors was practiced. By the 1960s, unibody construction in passenger cars had become common, and the trend towards building unibody passenger cars continued over the ensuing decades. Nearly all trucks, buses, and most Pickup truck, pickups continue to use a separate frame as their chassis. Functions The main functions of a frame in a motor vehicle ...

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.

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 Ro VIII Roland, 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.

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]   |

Northrop Alpha
The Northrop Alpha is 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 Corporation, 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: fillet (mechanics), 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 ra ...

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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
