Arado Ar 81
The Arado Ar 81 was a German prototype dive bomber. Because the Reich Air Ministry decided to purchase the competing Junkers Ju 87, only three prototypes of the Ar 81 were completed. Development In 1934, the Reich Air Ministry or RLM (''Reichsluftfahrtministerium'') initiated two parallel programmes to build new dive bombers for the German air force, to replace the Heinkel He 50. The first, the so-called ''Sofort'' or immediate program, aimed to develop an interim dive bomber, and resulted in the production of the Henschel Hs 123. The second, ''Sturzbomber'' program, aimed to produce a more definitive aircraft. In January 1935 the formal requirements for this were sent to German aircraft manufacturers.Herbert Léonard, ''Stukas! - Les Avions Allemands d'attaque au sol (1933-1945)'', Editions Heimdal, France 1997. These had been written around the Junkers Ju 87, of which the first prototype was already under construction. Indeed, the Luftwaffe had already given Junkers an order ...

Heinkel He 118
The Heinkel He 118 was a prototype German monoplane dive bomber design that lost out to the Junkers Ju 87 ''Stuka'' in the 1930s, and was never ordered by the ''Luftwaffe''. Design Designed by the Günter brothers, the He 118 followed many of the design notes of the Günter's designs of the era, notably the elliptical wing planform and rounded tail surfaces. It was in many ways an aluminum version of the mixed-construction Heinkel He 70 ''Blitz'', strengthened for dive bombing. It was a conventional cantilever monoplane with an inverted gull wing of elliptical planform mounted midway up the fuselage. It was considerably more streamlined than the Junkers competitor, with retractable landing gear and an internal bomb bay. As designed it was limited to filling a role similar to an attack bomber like the Henschel Hs 123 rather than a true dive bomber like the Junkers Ju 87. It was limited to bombing from a shallow angle, more properly known as "glide bombing", with the second crew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930s German Bomber Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 '' Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

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 ...

MG 15 Machine Gun
The MG 15 was a German 7.92 mm machine gun designed specifically as a hand-manipulated defensive gun for combat aircraft during the early 1930s. By 1941 it was replaced by other types and found new uses with ground troops. History The MG 15 was developed from the MG 30, which was designed by Rheinmetall using the locking system invented by Louis Stange in the mid to late 1920s. Though it shares the MG 15 designation with the earlier gun built by Bergmann, the MG 15nA (for ''neuer Art'', meaning new model having been modified from an earlier design) has nothing in common with the World War II gun except the model number. The World War I gun used a tipping lock system while the WWII aircraft gun uses a rotating bolt/lockring. The World War II MG 15 was used in nearly all Luftwaffe aircraft with a flexible-mount defensive position. It was a modular design with various attachments that could be quickly attached or removed. The bolt mechanism acted as a traditional open-bolt ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MG 17 Machine Gun
The MG 17 was a 7.92 mm machine gun produced by Rheinmetall-Borsig for use at fixed mountings in many World War II Luftwaffe aircraft, typically as forward-firing offensive armament. The MG 17 was based on the older MG 30 light machine gun, as was its defensive flexible-mount counterpart, the MG 15 machine gun. History A mainstay fixed machine gun in German built aircraft (many of which were sold to other countries) well before World War II, by 1940 it was starting to be replaced with heavier caliber machine gun and cannons. By 1945 very few if any aircraft mounted the MG 17. The MG 17 was installed in the Messerschmitt Bf 109, Messerschmitt Bf 110, Focke-Wulf Fw 190, Junkers Ju 87, Junkers Ju 88C Nightfighter, Heinkel He 111, Dornier Do 17/215 Nightfighter, Focke-Wulf Fw 189 and many other aircraft. Many MG 17s were later modified for infantry use, as the Luftwaffe replaced them with the heavier-calibre MG 131, which replaced both the MG 15 in bomber defense applicat ...

Junkers Jumo 210Ca
The Jumo 210 was Junkers Motoren's first production inverted V12 gasoline aircraft engine, first produced in the early 1930s. Depending on the version it produced between 610 and 730 PS and can be considered a counterpart of the Rolls-Royce Kestrel in many ways. Although originally intended to be used in almost all pre-war designs, rapid progress in aircraft design quickly relegated it to the small end of the power scale by the late 1930s. Almost all aircraft designs switched to the much larger Daimler-Benz DB 600, so the 210 was produced only for a short time before Junkers responded with a larger engine of their own, the Junkers Jumo 211. Design and development The first gasoline-burning aviation power plants that the Junkers Motorenwerke ever built were the L1 and L2 single overhead camshaft (SOHC) liquid-cooled inline-six aviation engines of the early and mid-1920s. Development of this line led up through the L8. All of these were developments of the BMW IIIa inline-six S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blohm & Voss Ha 137
The Hamburger Flugzeugbau Ha 137 was a German ground-attack aircraft of the 1930s. It was Blohm & Voss' entry into the contest to equip the re-forming ''Luftwaffe'' with its first purpose-built dive bomber. Although the contest would eventually be won by the Junkers Ju 87, the Ha 137 demonstrated that B&V's Hamburger Flugzeugbau, not even two years old at this point, had a truly capable design team of its own. One Ha 137 single-seat prototype competed against the Henschel Hs 123 at Rechlin. Design and development Hamburger had already designed a biplane trainer of no particular distinction, the Ha 135 under its first designer, Reinhold Mewes. Mewes then left to join another small company, Fieseler. In his place, Hamburger hired Richard Vogt, who had been working for a decade with Kawasaki Aircraft and was looking to return to Germany. Before leaving Japan, Vogt had been working on a new design for building wing spars, using a single chrome-plated steel tube (often ...

Henschel Hs 123
The Henschel Hs 123 was a single-seat biplane dive bomber and close-support attack aircraft flown by the German ''Luftwaffe'' during the Spanish Civil War and the early to midpoint of World War II. It proved to be robust, durable and effective especially in severe conditions. It continued to see front-line service until 1944, only to be withdrawn due to a lack of serviceable airframes and spare parts (production ended in 1940). Design and development Henschel was a German locomotive manufacturer. Soon after Hitler's rise to power, Henschel decided to start designing aircraft, one of the first being the Hs 123. The aircraft was designed to meet the 1933 dive bomber requirements for the reborn ''Luftwaffe''. Both Henschel and rival Fieseler (with the Fi 98) competed for the production contract requirement, which specified a single-seat biplane dive bomber. The first prototype, the Hs 123V1, was cleared for its maiden flight on 1 April 1935; General Ernst Udet, a World War I ace, ...

Heinkel He 50
The Heinkel He 50 was a German World War II-era dive bomber, originally designed for the Imperial Japanese Navy. Serving in ''Luftwaffe'' prewar dive-bombing units, the He 50 served until almost the end of World War II as a night harassment bomber. Design and development In 1931, the Japanese Navy placed an order with the Heinkel aircraft company for a two-seat dive bomber, capable of carrying 250 kg (550 lb) of bombs, stressed for catapult launches, and capable of using either wheeled or float undercarriages.Eden and Moeng, 2002, p. 830. A prototype, the Heinkel He 50aW, was completed in the summer of 1931. It was a biplane of mixed construction. The aircraft had twin floats and was powered by a Junkers L5 inline engine. The engine was found to be underpowered. A second prototype, the He 50aL, was built, powered by a Siemens Jupiter VI radial engine, having a wheeled undercarriage. A second He 50aL was built and redesignated He 50b. Based on the He 50b, a third proto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
