Albatros L 65
__NOTOC__ The Albatros L 65 was a German two-seat reconnaissance fighter biplane first flown in 1925. Design and development Under the Treaty of Versailles, military aircraft production was restricted in Germany, so Albatros Flugzeugwerke established a subsidiary to build the L 65 in Lithuania. This company was named Allgemeine Flug-Gesellschaft (A.F.G.) Memel, hence the L 65 was also known as the Memel A.F.G.1 (''Memel'' being the German name for the city of Klaipeda). The L 65 had a single-bay, staggered biplane configuration and was constructed of wood with a plywood skin. The wings were braced by interplane I-struts of broad aerofoil cross-section. Two prototypes were built, the first powered by a 340 kW (450 hp) water-cooled 12-cylinder "broad-arrow" Napier Lion engine; the second had its first flight in 1926 and had a 421 kW (565 hp) version of the Lion. The second prototype underwent evaluation by the '' Reichswehr'' to equip the clandestine tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Napier Lion
The Napier Lion is a 12-cylinder, petrol-fueled 'broad arrow' W12 configuration aircraft engine built by D. Napier & Son from 1917 until the 1930s. A number of advanced features made it the most powerful engine of its day and kept it in production long after other contemporary designs had been superseded. It is particularly well known for its use in a number of racing designs, for aircraft, boats and cars. Design and development Early in the First World War, Napier were contracted to build aero engines to designs from other companies, initially a Royal Aircraft Factory model and then Sunbeams. Both engines proved to be unreliable and in 1916 Napier decided to design an engine with high power, light weight and low frontal area. Napier's engineers laid out the engine with its 12 cylinders in what they called a "broad arrow"—three banks of four cylinders sharing a common crankcase. This suggested the design's first name, the Triple-Four. The configuration is also known as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Heinkel HD 17
The Heinkel HD 17 was a military reconnaissance aircraft produced in Germany in the late 1920s. Design The Heinkel HD 17 was a conventional single-bay biplane with strongly staggered wings of unequal span braced with N-type interplane struts. The pilot and observer sat in tandem, open cockpits, and the main units of the fixed, tailskid undercarriage were linked by a cross-axle. Operational history The Heinkel HD 17 first flew in 1924. In 1926, it was evaluated by the ''Reichswehr'' to equip the secret aviation training school at Lipetsk, and was selected in favour of the competing Albatros L 65. Seven aircraft were purchased and used briefly for training until replaced by more modern designs. Two Heinkel HD 17s were evaluated in 1924 by the US Army Air Service, being modified by Cox-Klemin to use a Napier Lion The Napier Lion is a 12-cylinder, petrol-fueled 'broad arrow' W12 configuration aircraft engine built by D.

Lipetsk Fighter-pilot School
The Lipetsk fighter-pilot school (german: Kampffliegerschule Lipezk), also known as WIWUPAL from its German codename ''Wissenschaftliche Versuchs- und Personalausbildungsstation'' "Scientific Experimental and Personnel Training Station", was a secret training school for fighter pilots operated by the German ''Reichswehr'' at Lipetsk, Soviet Union, because Germany was prohibited by the Treaty of Versailles from operating an air force and sought alternative means to continue training and development for the future ''Luftwaffe''. It is now the site of Lipetsk Air Base. Background The Treaty of Versailles, signed on 28 June 1919, prohibited Germany from operating any form of air force after the country had lost the First World War. Initially, it also prohibited the production and import of any form of aircraft to the country. In 1922, the clause on civilian aircraft was dropped and Germany was able to produce planes again, followed in 1923 with the country regaining control of its air ...

Reichswehr
''Reichswehr'' () was the official name of the German armed forces during the Weimar Republic and the first years of the Third Reich. After Germany was defeated in World War I, the Imperial German Army () was dissolved in order to be reshaped into a peacetime army. From it a provisional Reichswehr was formed in March 1919. Under the terms of the Treaty of Versailles, the rebuilt German army was subject to severe limitations in size and armament. The official formation of the Reichswehr took place on 1 January 1921 after the limitations had been met. The German armed forces kept the name 'Reichswehr' until Adolf Hitler's 1935 proclamation of the "restoration of military sovereignty", at which point it became part of the new . Although ostensibly apolitical, the Reichswehr acted as a state within a state, and its leadership was an important political power factor in the Weimar Republic. The Reichswehr sometimes supported the democratic government, as it did in the Ebert-G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intro ...

Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
