Hans Von Ohain
Hans Joachim Pabst von Ohain (14 December 191113 March 1998) was a German physicist, engineer, and the designer of the first operational jet engine. Together with Frank Whittle he is called the "father of the jet engine". His first test unit ran on hydrogen in March 1937, and it was a later development that powered the world's first flyable all-jet aircraft, the experimental Heinkel He 178 (He 178 V1) in late August 1939. In spite of these early successes, which started the world´s first jet producing industry in Germany, other German designs quickly eclipsed Ohain's, and none of his engine designs entered widespread production or operational use. Von Ohain started to develop his first turbojet engine designs independently during the same period that Whittle was working on his own similar designs in Britain, and their turbojet designs are said by some to be an example of simultaneous invention. The core of Ohain's first jet engine, the Heinkel HeS 1, which he described as his "hy ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dessau
Dessau is a town and former municipality in Germany at the confluence of the rivers Mulde and Elbe, in the '' Bundesland'' (Federal State) of Saxony-Anhalt. Since 1 July 2007, it has been part of the newly created municipality of Dessau-Roßlau. Population of Dessau proper: 67,747 (Dec. 2020). Geography Dessau is situated on a floodplain where the Mulde flows into the Elbe. This causes yearly floods. The worst flood took place in the year 2002, when the Waldersee district was nearly completely flooded. The south of Dessau touches a well-wooded area called Mosigkauer Heide. The highest elevation is a 110 m high former rubbish dump called Scherbelberg in the southwest of Dessau. Dessau is surrounded by numerous parks and palaces that make it one of the greenest towns in Germany. History Dessau was first mentioned in 1213. It became an important centre in 1570, when the Principality of Anhalt was founded. Dessau became the capital of this state within the Holy Roman Empire. In ...

Power Jets WU
The Power Jets WU (Whittle Unit) was a series of three very different experimental jet engines produced and tested by Frank Whittle and his small team in the late 1930s. Design and development The WU "First Model", also known by Whittle as the first "experimental" engine, and the "1st edition","The Early History of the Whittle Jet Propulsion Gas Turbine" The First James Clayton Lecture 1945, Air Commodore Frank Whittle, Institution of Mechanical Engineers, London was the first turbojet engine to be built and run in the world. Although an experimental engine and not intended for flight it was designed to be very light by normal engineering standards. The engine had four basic components: a single stage centrifugal compressor with double-sided impeller, a single straight-through combustion chamber, a single stage, axial flow turbine and a convergent propelling nozzle attached to a jet pipe. The shaft connecting the turbine to the compressor was made as short as possible to avoid ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Heinkel He 280
The Heinkel He 280 was the first turbojet-powered fighter aircraft in the world. It was inspired by Ernst Heinkel's emphasis on research into high-speed flight and built on the company's experience with the He 178 jet prototype. A combination of technical and political factors led to it being passed over in favor of the Messerschmitt Me 262. Only nine were built and none reached operational status. Development The Heinkel company began the He 280 project on its own initiative after the He 178 had failed to interest the '' Reichsluftfahrtministerium (R.L.M.)'' (the German Reich Aviation Ministry ). The head designer was Robert Lusser, who began the project under the designation He 180 in late 1939. It had a typical Heinkel fighter fuselage, semi-elliptical wings and a dihedralled tailplane with twin fins and rudders. It had a tricycle undercarriage with very little ground clearance. This arrangement was considered too frail for the grass or dirt airfields of the era; however, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Heinkel HeS 8
The Heinkel HeS 8 (prefix being an abbreviation for "Heinkel Strahltriebwerke 8" - ''Heinkel Jet Engine 8'') was an early jet engine designed by Hans von Ohain while working at Heinkel. It was the first jet engine to be financially supported by the RLM, bearing the official name 109-001. Had development continued it would have been known as the Heinkel 001, but it does not appear this was used in practice. The HeS 8 was intended to power the Heinkel He 280 twin-engine fighter, although both Heinkel and von Ohain preferred the axial HeS 30. A lengthy gestation period meant it was finally becoming ready for production at about the same time as the Junkers Jumo 004 and BMW 003. In 1942 work was ended on the HeS 8 and HeS 30, and Heinkel was ordered to move on to the larger Heinkel HeS 011 instead. The He 280 was left engineless, and was eventually abandoned. Design and development By the time the HeS 3 program wound down in 1939, it appears that von Ohain no longer favoured the ...

Test Pilot
A test pilot is an aircraft pilot with additional training to fly and evaluate experimental, newly produced and modified aircraft with specific maneuvers, known as flight test techniques.Stinton, Darrol. ''Flying Qualities and Flight Testing of the Airplane.'' American Institute of Aeronautics and Astronautics, Inc., 1996, p. 265 History Test flying as a systematic activity started during the First World War, at the Royal Aircraft Establishment (RAE) in the United Kingdom. An "Experimental Flight" was formed at the Central Flying School. During the 1920s, test flying was further developed by the RAE in the UK, and by the National Advisory Committee for Aeronautics (NACA) in the United States. In the 1950s, NACA was transformed into the National Aeronautics and Space Administration, or NASA. During these years, as work was done into aircraft stability and handling qualities, test flying evolved towards a more qualitative scientific profession. In the 1950s, test pilots were ...

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 ev ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...

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 ...

Erich Warsitz
Erich Warsitz (18 October 1906, Hattingen, Westphalia – 12 July 1983) was a German test pilot of the 1930s. He held the rank of Flight-Captain in the Luftwaffe and was selected by the Reich Air Ministry as chief test pilot at Peenemünde West. He is remembered as the first person to fly an aircraft under liquid-fueled rocket power, the Heinkel He 176, on June 20, 1939 and also the first to fly an aircraft under turbojet power, the Heinkel He 178, on August 27 the same year. Biography Aviation career Warsitz was born at Hattingen. Together with his practical tuition and technical studies, Erich Warsitz’ aeronautical training as a sport flier for the A-2 licence began at the Academic Aviation Group Bonn/Hangelar (1929-1930). In stages subsequently came the B-1 and B-2 training at various aerodromes of the contemporary sports associations, and further training at DVS ( German Commercial Pilot School) at Stettin for the C-2 (land aircraft and commercial carriage of persons) ...
