Twin-boom
A twin-boom aircraft is characterised by two wikt:Longitudinal, longitudinal booms (extended nacelle-like bodies). The booms may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the Empennage, tail surfaces, although on some types such as the Rutan Grizzly, Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from Twin-fuselage aircraft, twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the twin-fuselage aircraft, twin fuselage type in having a separate, short fuselage housing the pilot and payload. It has been adopted to resolve various design problems with the conventional empennage for aircraft in different roles. Engine mounting For a single engine with a propeller in the pusher configuration or a jet engine, a conventional tail requires the propeller or exhaust to be moved far aft, ...

Saab 21R
The Saab 21R was a Swedish fighter/ attack aircraft developed and produced by Svenska Aeroplan AB (SAAB). It was a jet-powered development of the piston-engined SAAB 21 and was the first jet aircraft to be produced by Saab. The R-suffix stands for ''reaktion'' (reaction), referencing ''reaktionsdrift'' (jet power) or ''reaktionsmotor'' (jet engine). Along with the Soviet Yakovlev Yak-15, the 21R was one of only two jet fighters to have been successfully converted from piston-powered aircraft. Sweden was under threat during the Second World War, and ordered SAAB to develop an advanced fighter. The result was an unorthodox twin-boom pusher, with a low wing, tricycle landing gear, and a heavy forward-firing armament. Several options were then explored to improve its performance, leading to a jet-powered version. During 1947, SAAB began converting the piston-engined J 21s to jet propulsion, which required extensive modifications. 124 aircraft were planned, however this was red ...

Focke-Wulf Fw 189
The Focke-Wulf Fw 189 ''Uhu'' ("Eagle Owl") is a German twin-engine, twin-boom, three-seat tactical reconnaissance and army cooperation aircraft. It first flew in 1938 (Fw 189 V1), entered service in 1940 and was produced until mid-1944. In addition, Focke-Wulf used this airframe in response to a tender request by the RLM for a dedicated ground-attack airplane, and later submitted an armored version for trials. However, the Henschel Hs 129 was selected instead. Design and development In 1937, the German Ministry of Aviation issued a specification for a short-range, three-seat reconnaissance aircraft with a good all-round view to support the German army in the field, replacing the Henschel Hs 126, which had just entered service. A power of about 850–900 hp (630–670 kW) was specified. The specification was issued to Arado and Focke-Wulf. Arado's design, the Ar 198, which was initially the preferred option, was a relatively conventional single-engined high-wing mo ...

Twin-fuselage Aircraft
A twin-fuselage aircraft has two main fuselages. It is distinct from the twin-boom configuration which has a single main fuselage with two subsidiary boom structures. Twin fuselages have been adopted for various reasons, and a few types have entered production. Early seaplanes A twin-float arrangement offers stability on the water without the need for wing tip stabilising floats. Mounting the float immediately below, or integrally with, the fuselage provides a strong airframe with minimal additional weight. During and after World War I a number of such twin-fuselage floatplanes and twin-hulled flying boats were constructed, and a few entered production. As early as 1913, the Radley-England Waterplane racing flying boat demonstrated the concept at the hands of pilot Gordon England. The Twin Blackburn of 1915 was a long-range floatplane for anti-Zeppelin patrol. A handful of production examples were delivered but few were used operationally. Savoia-Marchetti produced two tw ...

Caproni Ca
Caproni, also known as ''Società de Agostini e Caproni'' and ''Società Caproni e Comitti'', was an Italian aircraft manufacturer. Its main base of operations was at Taliedo, near Linate Airport, on the outskirts of Milan. Founded by Giovanni Battista "Gianni" Caproni during 1908, the company produced several successful heavy bombers during the First World War. Following the acquisition of several other aviation firms throughout the interwar period, Caproni transformed into a sizable aviation-orientated syndicate, the ''Società Italiana Caproni, Milano''. The majority of its aircraft were bombers and transport aircraft. It played a pioneering role in the development of the Caproni Campini N.1, an experimental aircraft powered by a thermo-jet. It provided large numbers of combat aircraft for the Axis during the Second World War. The firm did not prosper in the postwar era, the Società Italiana Caproni collapsing during 1950. Many of the company's former assets were s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed P-38 Lightning
The Lockheed P-38 Lightning is an American single-seat, twin piston-engined fighter aircraft that was used during World War II. Developed for the United States Army Air Corps by the Lockheed Corporation, the P-38 incorporated a distinctive twin boom, twin-boom design with a central nacelle containing the cockpit and armament. Along with its use as a general fighter aircraft, fighter, the P-38 was used in various aerial combat roles, including as a highly effective fighter-bomber, a night fighter, and a Range (aircraft), long-range escort fighter when equipped with drop tanks. The P-38 was also used as a bomber-pathfinder, guiding streams of medium bomber, medium and heavy bombers, or even other P-38s equipped with bombs, to their targets."P-38 Lightning" National M ...

Bakelite
Polyoxybenzylmethylenglycolanhydride, better known as Bakelite ( ), is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York in 1907, and patented on December 7, 1909 (). Because of its electrical nonconductivity and heat-resistant properties, it became a great commercial success. It was used in electrical insulators, radio and telephone casings, and such diverse products as kitchenware, jewelry, pipe stems, children's toys, and firearms. The " retro" appeal of old Bakelite products has made them collectible. The creation of a synthetic plastic was revolutionary for the chemical industry, which at the time made most of its income from cloth dyes and explosives. Bakelite's commercial success inspired the industry to develop other synthetic plastics. In recognition of its significance as the world's first commercial ...

Nieuport Pusher
Nieuport, later Nieuport-Delage, was a French aeroplane company that primarily built racing aircraft before World War I and fighter aircraft during World War I and between the wars. History Beginnings Originally formed as Nieuport-Duplex in 1902 for the manufacture of engine components the company was reformed in 1909 as the Société Générale d'Aéro-locomotion, and its products were marketed to the aviation industry, including ignition components. During this time they built their first aircraft, a small single-seat pod and boom monoplane. This was destroyed shortly after having been flown successfully, during the Great Flood of Paris in 1909 . A second design flew before the end of 1909 and had the essential form of modern aircraft, including an enclosed fuselage with the pilot protected from the slipstream and a horizontal tail whose aerodynamic force acted downwards, balancing the weight of the engine ahead of the centre of gravity, as opposed to upwards as on contempo ...

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 ...

Aluminium
Aluminium (aluminum in AmE, American and CanE, Canadian English) is a chemical element with the Symbol (chemistry), symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and Passivation (chemistry), forms a protective layer of Aluminium oxide, oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, Magnetism, non-magnetic and ductility, ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of Aluminum-26, 26Al is used in Radiometric dating, radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...
