Bundesarchiv Bild 183-1982-1022-509, Flugzeugkonstrukteur Prof
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media (Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior (Germany), Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest docum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinkel He 70
The Heinkel He 70 ''Blitz'' ("lightning") was a fast monoplane aircraft designed and produced by the German aircraft manufacturer Heinkel, Heinkel Flugzeugwerke. It was the first ''Schnellbomber'' operated by the Luftwaffe. Development of the He 70 began in the early 1930s in response to a request from ''Deutsche Lufthansa'' for a fast mail plane. Heinkel designed a low-wing cantilever monoplane with various measures to minimise Drag_(physics)#Aerodynamics, drag, including an aerodynamically efficient elliptical wing, a smooth external finish, and a retractable undercarriage. The He 70 was powered by a single BMW VI 7.3 Z engine and cooled by a compact retractable Radiator (engine cooling), radiator as a further drag-reducing measure. The first prototype made its maiden flight on 1 December 1932 and set eight separate Flight airspeed record, world speed records over the following months. The He 70 was adopted by Deutsche Lufthansa in 1934, although its commercial career was rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinkel He 177
The Heinkel He 177 ''Greif'' (Griffin) was a long-range heavy bomber flown by the ''Luftwaffe'' during World War II. The introduction of the He 177 to combat operations was significantly delayed by problems both with the development of its engines and frequent changes to its intended role. Nevertheless, it was the only long-range, heavy bomber to become operational with the ''Luftwaffe'' during the conflict. The He 177 had Payload#Relationship of range and payload, a payload/range capability similar to that of four-engined heavy bombers used by the Allies in the Western Front (World War II), European theatre. Work on the design began in response to a 1936 requirement known as Bomber A, issued by the Ministry of Aviation (Nazi Germany), ''Reichsluftfahrtministerium'' (RLM) for a purely strategic bomber. Thus, the He 177 was intended originally to be capable of a sustained bombing campaign against Soviet Union, Soviet manufacturing capacity, Ural economic region, dee ...

He 219
The Heinkel He 219 ''Uhu'' (" Eagle-Owl") is a night fighter designed and produced by the German aircraft manufacturer Heinkel. It primarily served with the ''Luftwaffe'' in the later stages of the Second World War. Work on the He 219 began in mid 1940 as a multi-purpose aircraft designated ''P.1055''. It was a relatively sophisticated design that possessed a variety of innovations, including a Cabin pressurization, pressurized cockpit, twin ejection seats and remotely controlled defensive Aircraft gun turret, gun turrets. The P.1055 was initially rejected by the ''Ministry of Aviation (Germany), Reichsluftfahrtministerium'' (RLM – the German Aviation Ministry), but Heinkel promptly reconfigured it as a night fighter, designated ''P.1060''. In this capacity, it was equipped with a Lichtenstein radar#FuG 220 Lichtenstein SN-2, Lichtenstein SN-2 advanced VHF-band intercept radar (also used on the Junkers Ju 88, Ju 88G and Messerschmitt Bf 110, Bf 110G night fighters).

Heinkel He 113
The Heinkel He 113 was a fictitious German fighter aircraft of World War II, invented as a propaganda and possibly disinformation exercise. Development In 1940 in aviation, 1940, Nazi Minister of Propaganda Joseph Goebbels publicised the fact that a new fighter was entering service with the ''Luftwaffe''. The plan involved taking pictures of Heinkel He 100 D-1s at different air bases around Germany, each time sporting a new paint job for various fictional fighter groups. The pictures were then published in the press with the He 113 name, sometimes billed as night fighters (despite lacking even a Landing lights, landing light). The aircraft also appeared in a series of "action shot" photographs in various magazines such as ''Der Adler'', including claims that it had proven itself in combat in Denmark and Norway. One source claims that the aircraft were on loan to the one ''Luftwaffe'' ''Staffel'' in Norway for a time, but this might be a case of the same misinformation working m ...

Hans Von Ohain
Hans Joachim Pabst von Ohain (14 December 191113 March 1998) was a German physicist, engineer, and the designer of the first aircraft to use a turbojet engine. Together with Frank Whittle and Anselm Franz, he has been described as the co-inventor of the turbojet engine. However, the historical timelines show that von Ohain was still a university student when, in January 1930, Whittle filed his first patent for a turbojet engine and successfully tested his first engine in April 1937, some 6 months before von Ohain. Additionally, prior to building his engine and filing his own patent in 1935, von Ohain had read and critiqued Whittle's patents.Margaret Conner, Hans von Ohain: Elegance in Flight (Reston, Virginia: American Institute for Aeronautics and Astronautics, Inc., 2001), page 31 Von Ohain stated in his biography that "My interest in jet propulsion began in the fall of 1933 when I was in my seventh semester at Göttingen University. I didn't know that many people before me had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinkel He 176
The Heinkel He 176 was a German experimental rocket-powered aircraft. It was the world's first aircraft to be propelled solely by a liquid-fueled rocket, making its first powered flight on 20 June 1939 with Erich Warsitz at the controls. The He 176 was developed as a private venture by the Heinkel company in accordance with director Ernst Heinkel's emphasis on developing technology for high-speed flight. Work on the project began in 1936 after testing with a modified He 72 and a pair of He 112s had shown rocket propulsion to have some viability. The He 176 was purpose-built to harness this propulsion, rather than a modification of existing piston engined-types. The resulting aircraft, largely composed of wood, was of relatively simple build in some aspects, and relatively compact. It incorporated some novel concepts, such as an unconventional reclined seating position for the pilot and a unique jettisonable nose escape system for emergencies. In December 1937 the aircraft was ... [...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-powere ...

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 ...

Planform
In technical drawing and computer graphics, a multiview projection is a technique of illustration by which a standardized series of orthographic projection, orthographic two-dimensional pictures are constructed to represent the form of a three-dimensional object. Up to six pictures of an object are produced (called ''primary views''), with each projection plane parallel to one of the coordinate axes of the object. The views are positioned relative to each other according to either of two schemes: ''first-angle'' or ''third-angle'' projection. In each, the appearances of views may be thought of as being ''projected'' onto planes that form a six-sided box around the object. Although six different sides can be drawn, ''usually'' three views of a drawing give enough information to make a three-dimensional object. These three views are known as front view (also elevation view), top view or plan view and end view (also profile view or section view). When the plane or axis of the ob ...

Elliptical Wing
An elliptical wing is a wing planform whose leading and trailing edges each approximate two segments of an ellipse. It is not to be confused with annular wings, which may be elliptically shaped. Relatively few aircraft have adopted the elliptical wing, an even-smaller number of which attained mass production; the majority of aircraft that did use this feature were introduced during the 1930s and 1940s. Perhaps the most famous aircraft to feature an elliptical wing is the Supermarine Spitfire, a Second World War-era British fighter aircraft. Another example was the Heinkel He 70 "Blitz", a German fast mail plane and reconnaissance bomber; early versions of the He 111 bomber also used such a wing configuration before a simpler design was adopted for economic reasons. Properties Theoretically, the most efficient way to create lift is to generate it in an elliptical spanwise distribution across the wing. There is no inherent superiority to pure elliptical shapes and wings with oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
