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 whic ...

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

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 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 Peter Williams' 1973 ...

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 chas ...

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. This construction design is known as '' body-on-frame''. By the 1960s, unibody construction in passenger cars had become common, and the trend to unibody for passenger cars continued over the ensuing decades. Nearly all trucks, buses, and most pickups continue to use a separate frame as their chassis. Functions The main functions of a frame in a motor vehicle are: # To support the vehicle's mechanical components and body # To deal with static and dynamic loads, without undue deflection or distortion. :These include: ::*Weight of the body, passengers, and cargo loads. ::*Vertical and torsional twisting transmitted by going over uneven surfaces. ::*Transverse lateral forces caused by road condi ...

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, includin ... [...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. Models * Rohrbach RoI * Rohrbach Ro II The Rohrbach Ro II was an all-metal, 4-seat reconnaissance and bomber flyi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 re ...

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