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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dive Bomber
A dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even ''en masse''. After World War II, the rise of precision-guided munitions and improved anti-aircraft defences—both fixed gunnery positions and fighter interception—led to a fundamental change in dive bombing. New weapons, such as rockets, allowed for better accuracy from smaller dive angles and from greater distances. They could be fitted to almost any aircraft, including fighters, improving their effectiveness without the inherent vulnerabilities of dive bombers, which needed air superiority to operate effectively. Method A dive bomber dives at a steep angle, normally between 45 and 60 degrees or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

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 m ... [...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 The MG 131 (shortened from German: ''Maschinen ...

Daimler-Benz DB 600C
The Daimler-Benz DB 600 was a German aircraft engine designed and built before World War II as part of a new generation of German engine technology. It was a liquid-cooled inverted V12 engine, and powered the Messerschmitt Bf 110 and Heinkel He 111 among others. Development Most newer DB engine designs used in WW2 were based on this engine. The RLM made a set of specifications listing the technologies which the new class of German aero-engines required. Among these items was fuel injection systems rather than carburettors. Knowing that this would take some years to implement, the RLM permitted that the manufacturers could first design and produce the basic engine, and later develop it to include the injection system. The DB 600 formed this function (having in turn been developed from the Daimler-Benz F4A and F4B V12s), therefore when the injection system was ready it meant that the DB 600 was replaced by the otherwise similar DB 601, which in addition to direct fuel injec ...

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery. ...

Imperial Japanese Navy Air Service
The was the air arm of the Imperial Japanese Navy (IJN). The organization was responsible for the operation of naval aircraft and the conduct of aerial warfare in the Pacific War. The Japanese military acquired their first aircraft in 1910 and followed the development of air combat during World War I with great interest. They initially procured European aircraft but quickly built their own and launched themselves onto an ambitious aircraft carrier building program. They launched the world's first purpose-built aircraft carrier, , in 1922. Afterwards they embarked on a conversion program of several excess battlecruisers and battleships into aircraft carriers. The IJN Air Service had the mission of national air defence, deep strike, naval warfare, and so forth. It retained this mission to the end. The Japanese pilot training program was very selective and rigorous, producing a high-quality and long-serving pilot corps, who were very successful in the air during the early p ...

Heinkel He 178
The Heinkel He 178 was an experimental aircraft designed and produced by the German aircraft manufacturer Heinkel. It was the world's first aircraft to fly using the thrust from a turbojet engine. The He 178 was developed to test the jet propulsion concept devised by the German engineer Hans von Ohain during the mid-1930s. Having secured the industrial support of Ernst Heinkel, von Ohain was able to demonstrate a working turbojet engine, the Heinkel HeS 1, in September 1937. Heinkel pursued development of the He 178 as a private venture, independent of the German authorities and the Luftwaffe, keeping the aircraft relatively secret for much of its development. Heinkel was keen not only to demonstrate the capabilities of aviation gas turbines, but had a separate emphasis on developing high-speed flight technologies. On 27 August 1939, the He 178 V1, the first prototype, performed its maiden flight, piloted by Erich Warsitz. This flight, which only lasted for six minutes, had ...

Conventional Landing Gear
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-pow ...

Heinkel HeS 3
The Heinkel HeS 3 (HeS - ''Heinkel Strahltriebwerke'') was the world's first operational jet engine to power an aircraft. Designed by Hans von Ohain while working at Heinkel, the engine first flew as the primary power of the Heinkel He 178, piloted by Erich Warsitz on 27 August 1939. Although successful, the engine had too little thrust to be really useful, and work started on the more powerful Heinkel HeS 8 as their first production design. Development The HeS 3 design was largely based on the HeS 1 but converted to burn liquid fuel instead of hydrogen gas used in the HeS 1. The first HeS 3 design was generally similar to the HeS 1, using an 8-blade inducer and 16-blade centrifugal compressor. The compressed air flowed into an annular combustion chamber between the compressor and turbine, which made the engine longer. The first example was bench tested around March 1938, but did not reach the design thrust because a small compressor and combustor had been used to reduce the front ...
