Arado Ar 340
The Arado Ar E.340 was a twin-engined dive- and tactical-medium bomber, designed by Arado Flugzeugwerke at the request of the Reich Air Ministry in 1939 to compete for a production contract for the ''Bomber B'' fast bomber design competition, but the project was cancelled. Design and development The Reich Air Ministry ordered the aircraft to replace the Junkers Ju 88 and Dornier Do 217 bombers by 1943. Four manufacturers submitted plans to the Air Ministry, which chose the Arado design. The engines were positioned in a unique twin-boom arrangement connected only through the wing assembly, a configuration which offered the crew better visibility. The Arado E.340 was designed with a central fuselage containing all four crew members. The cockpit and rear compartment were glazed and pressurized. The Jumo engines and landing gear were mounted to the load-bearing wing centre-section. The tail of the aircraft was a unique design, where the tailplane did not connect the two booms but was ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daimler-Benz DB 604
The Daimler-Benz DB 604 was an experimental German 24-cylinder aircraft engine, which did not progress beyond the initial engine testing phase and was ultimately abandoned in 1942. Design and development The DB 604 was unique among the DB 600 series of aircraft engines by having its 24 cylinders arranged in an X, with four inline rows of six cylinders. The DB 604 was also unique amongst the X-24 engines, in that it was not conceived as a further development of existing Daimler-Benz aircraft engines such as the DB 601, DB 603 or DB 605, which themselves had been twinned-up as two separate powerplants sharing a new common gear reduction case at their front ends, into the 1.5-tonne dry weight DB 601-based "coupled" DB 606 in February 1937, the same-weight figured DB 605-based DB 610 by June 1940, and just slightly earlier, in March 1940, the 1.8 tonne approximate weight replacement for the DB 606 and 610, the DB 603-based DB 613 "power system" of nearly 3,500 PS output.

Twin-boom Aircraft
A twin-boom aircraft is characterised by two 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 tail surfaces, although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the 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, requiring either a very long driveshaft or jet pipe and thus reducing propulsive efficien ...

MG 131
The MG 131 (shortened from German: ''Maschinengewehr'' 131, or "Machine gun 131") was a German 13 mm caliber machine gun developed in 1938 by Rheinmetall-Borsig and produced from 1940 to 1945. The MG 131 was designed for use at fixed, flexible or turreted, single or twin mountings in Luftwaffe aircraft during World War II. It was one of the smallest, if not the smallest among the heavy machine guns of that conflict, with a weight of 16.6 kilograms (37 lb,) less than 60% of the M2 Browning or the Breda-SAFAT machine gun. Despite this, the MG 131 was a rapid fire weapon with an elevated firepower for its mass. It was equipped with HEI ammunition. Its nearest contemporary equivalent may have been the Japanese Ho-103, itself based on the earlier American M1921 Browning machine gun. The other main Axis automatic weapon of similar caliber, the Italian Breda 12.7 mm was around 13 kg heavier and bigger, while slower by at least 150 rpm. This small size allowed them to be mou ...

MG 151/20
The MG 151 (MG 151/15) was a German 15 mm aircraft-mounted autocannon produced by Waffenfabrik Mauser during World War II. Its 20mm variant, the 20 mm MG 151/20 cannon, was widely used on German Luftwaffe fighters, night fighters, fighter-bombers, bombers and ground-attack aircraft. Salvaged guns saw post-war use by other nations. Development and wartime history (MG 151/20) The pre-war German doctrine for arming single-engine fighter aircraft mirrored that of the French. This doctrine favoured a powerful autocannon mounted between the cylinder banks of a V engine and firing through the propeller hub, known as a ''moteur-canon'' in French (from its first use with the Hispano-Suiza HS.8C engine in World War I, on the SPAD S.XII) and by the cognate ''Motorkanone'' in German by the 1930s. The weapon preferred by the French in this role was the most powerful 20mm Oerlikon of the time, namely the FFS model, but this proved too big for German engines. Mauser was given the ...

BMW 802
The BMW 802 was a large air-cooled radial aircraft engine, built using two rows of nine cylinders to produce what was essentially an 18-cylinder version of the 14-cylinder BMW 801. Although promising at first, development dragged on and the project was eventually cancelled to concentrate on jet engines instead. Design and development Soon after the 801 entered testing, BMW engineers turned to building much larger versions. One idea was to bolt two 801s back to back. Although seemingly a simple concept, the resulting, 83.5 litre displacement BMW 803 was in fact fantastically complicated. The power of the engine could only practically be used in extremely large propellers, or, as selected, a contra-rotating pair of propellers. This required a large gearbox on the front of the engine, which combined with the layout of the cylinders, left no room for airflow over the cylinders. This demanded the addition of liquid cooling. Another idea was to add more cylinders to the 801 design, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junkers Jumo 222
The Jumo 222 was a German high-power multiple-bank in-line piston aircraft engine from Junkers, designed under the management of Ferdinand Brandner of the Junkers Motorenwerke. Such was the projected performance of the engine compared to contemporary designs that many developments of wartime Luftwaffe piston-engined aircraft designs were based on it, at least as an option. These included the entire Bomber B program, which looked to replace all existing Luftwaffe bombers with a new twin-engine design that was larger, faster and more heavily armed than any aircraft in their inventory. The design failed to mature even after years of intensive development and several major design changes. The Bomber B program failed along with it, leaving the ''Luftwaffe'' with hopelessly outdated designs during the second half of the war. Only a small number of 222s were built, less than 300. They never left the prototype phase, but the design nevertheless continued appearing on proposals for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arado Flugzeugwerke
Arado Flugzeugwerke was a German aircraft manufacturer, originally established as the Warnemünde factory of the Flugzeugbau Friedrichshafen firm, that produced land-based military aircraft and seaplanes during the First and Second World Wars. History With its parent company, it ceased operations following the First World War, when restrictions on German aviation were created by the Treaty of Versailles. In 1921, the factory was purchased by Heinrich Lübbe, who is said to have assisted Anthony Fokker in the creation of the pioneering ''Stangensteuerung'' synchronization gear system during 1914-15, and re-commenced aircraft construction for export, opening a subsidiary, Ikarus, in Yugoslavia. Walter Rethel, previously of Kondor and Fokker, was appointed head designer. In 1925, the company joined the Arado Handelsgesellschaft ("Arado trading firm") that was founded by the industrialist Hugo Stinnes Jr.https://www.nytimes.com/1929/07/14/archives/asks-jail-sentence-for-hugo-stinnes ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
