Arado SD III
__NOTOC__ The Arado SD III was a fighter biplane developed in Germany in the 1920s. It was developed in parallel with the SD II and shared most of that aircraft's airframe design. The main differences were connected with the powerplant installation, which in turn required a shorter forward fuselage and redesigned undercarriage. Evaluated at Staaken, Rechlin and finally at Lipetsk Lipetsk ( rus, links=no, Липецк, p=ˈlʲipʲɪtsk), also romanized as Lipeck, is a city and the administrative center of Lipetsk Oblast, Russia, located on the banks of the Voronezh River in the Don basin, southeast of Moscow. Populatio ..., it was judged unsuitable for mass production, but the lessons learned from it proved invaluable to Arado in designing the Ar 64 and Ar 65.

Lipetsk
Lipetsk ( rus, links=no, Липецк, p=ˈlʲipʲɪtsk), also romanized as Lipeck, is a city and the administrative center of Lipetsk Oblast, Russia, located on the banks of the Voronezh River in the Don basin, southeast of Moscow. Population: History Lipetsk was first mentioned in the 13th century chronicles. The name means " Linden city" and is cognate with Leipzig and Liepāja. In 1284, the city was destroyed by the Mongols. The foundation of the modern city dates back to 1703,Charter of Lipetsk, Article 1 when Peter the Great ordered construction of a cast iron factory in Lipetsk near the iron ore deposits for making artillery shells. On September 27, 1779, Lipetsk was granted town status. It became one of the principal towns of Tambov Governorate. In 1879, Lipetsk hosted a congress of members of Land and Liberty. After the Treaty of Rapallo (1922) until 1933, the much-reduced German Army (''Reichswehr'') of the Weimar Republic secretly contracted with S ...

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

Hawker Woodcock
The Hawker Woodcock was a British single-seat fighter built by the Hawker Engineering Company as the first fighter to be produced by Hawker Engineering (the successor to Sopwith Aviation). It was used by the RAF as a night fighter in the 1920s. Design and development The Hawker Woodcock was designed as a night fighter in 1922 to meet specification 25/22. The chief designer was Captain Thomson, and the prototype, serial number ''J6987'', was first flown with a 358 hp (267 kW) Armstrong Siddeley Jaguar II engine in March 1923 with F. P. Raynham at the controls. It featured a two-bay wing.Mason 1992, p. 168Mason 1991, p. 103 The prototype was rejected because of lack of manoeuvrability as well as suffering from serious wing flutter and ineffective rudder control, with spinning prohibited.Mason 1991, pp. 102–103 Following the first flight W. G. Carter took over as chief designer and changed the design, reducing the wingspan by 2 ft (0.61 m) and making ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gloster Gamecock
The Gloster Gamecock was a biplane fighter designed and produced by the British aircraft manufacturer Gloster. The Gamecock was a development of the earlier Grebe Mk III, an early interwar fighter procured by the Royal Air Force (RAF). Work on the type commenced in 1924 as a response to Air Ministry Specification 37/23. The principal difference between the two aircraft was the adoption of the Bristol Jupiter radial engine for the Gamecock. in the place of the somewhat unreliable Armstrong Siddeley Jaguar. Various other structural improvements were also made to the fuselage, the armament was also revised to include internally-mounted machine guns. On 22 February 1925, the prototype Gamecock performed its maiden flight. Evaluation flights at RAF Martlesham Heath resulted in considerable praise for the aircraft; few changes were made as a result. During September 1925, the Air Ministry placed an initial order for 30 production aircraft to fulfil Specification 18/25. Furthe ...

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Jupiter
The Bristol Jupiter was a British nine-cylinder single-row piston radial engine built by the Bristol Aeroplane Company. Originally designed late in World War I and known as the Cosmos Jupiter, a lengthy series of upgrades and developments turned it into one of the finest engines of its era. The Jupiter was widely used on many aircraft designs during the 1920s and 1930s. Thousands of Jupiters of all versions were produced, both by Bristol and abroad under licence. A turbo-supercharged version of the Jupiter known as the Orion suffered development problems and only a small number were produced. The "Orion" name was later re-used by Bristol for an unrelated turboprop engine. Design and development The Jupiter was designed during World War I by Roy Fedden of Brazil Straker and later Cosmos Engineering. The first Jupiter was completed by Brazil Straker in 1918 and featured three carburettors, each one feeding three of the engine's nine cylinders via a spiral deflector housed ins ...

Siemens-Halske
Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as ''Telegraphen-Bauanstalt von Siemens & Halske'' by Werner von Siemens and Johann Georg Halske. The company, located in Berlin-Kreuzberg, specialised in manufacturing electrical telegraphs according to Charles Wheatstone's patent of 1837. In 1848, the company constructed one of the first European telegraph lines from Berlin to Frankfurt am Main. Siemens & Halske was not alone in the realm of electrical engineering. In 1887, Emil Rathenau had established ''Allgemeine Elektrizitäts-Gesellschaft'' (AEG), which became a long-time rival. In 1881, Siemens & Halske built the Gross-Lichterfelde Tramway, the world's first electric streetcar line, in the southwestern Lichterfelde suburb of Berlin, followed by the Mödling and Hinterbrühl Tram near Vienna, the first electrical interurban tram in Austria-Hungary. 1882 saw the open ...

Arado Ar 65
The Arado Ar 65 was the single-seat biplane fighter successor to the Ar 64. Both looked very similar. The only major difference was the use of a 12-cylinder inline engine versus the Ar 64's radial. The wingspan was also increased. The Ar 65 appeared in 1931 and six models were built. The first three 65a-c were prototypes, while the 65d-f were production models. The Ar 65d was delivered in 1933 and served alongside the Ar 64 in the two fighter groups - ''Fliegergruppe'' Döberitz and ''Fliegergruppe'' Damm. In 1935, the Ar 65 was reduced to a training aircraft. Production of the fighter was discontinued in 1936. However, the next year, 12 of them were presented to Germany's ally - the Royal Bulgarian Air Force. The final production total was 85 aircraft. Variants ;Ar 65a: Prototype, powered by a 559 kW (750 hp) BMW VI 7.3 12-cylinder water-cooled engine.

Arado Ar 64
The Arado Ar 64 was a single-seat biplane fighter, developed in the late 1920s. It was among the first fighters produced when Germany abandoned the restrictions of the Treaty of Versailles and began rearming. Design and development The Ar 64 was a derivative of the earlier Arado SD II and Arado SD III, based upon the ''Reichswehrministerium''s ( Reich War Ministry) requirement for a successor to the Fokker D.XIII fighter. The AR 64D and 64E would be the first fighters built in quantity by Germany since the end of World War I. The two differed, as the 64D had a revised undercarriage and a four-blade propeller, and the 64E had a two-blade propeller attached to a direct-drive version of the Jupiter VI radial engine. In the summer of 1932, 20 aircraft of both types were ordered and 19 of them were assigned to the ''Jagdfliegerschule'' at Schleissheim and the ''Jagdstaffeln'' of the ''Fliegergruppe'' Doberitz and ''Fliegergruppe'' Damm.
