Neptun Radar
(Neptune) was the code name of a series of low-to-mid-VHF band airborne intercept radar devices developed by Germany in World War II and used as active targeting devices in several types of aircraft. They were usually combined with a "backwards warning device", indicated by the addition of the letters "V/R" , meaning Forward/Backward). Working in the metre range, Neptun was meant as a stop-gap until scheduled SHF-band devices became available (for instance the FuG 240/E cavity magnetron-based FuG 240 Berlin AI radar). Transceiving antennas used for on twin-engined night fighters usually used a (stag's antlers) eight-dipole array with shorter elements than the previous 90 MHz SN-2 radar had used or as an experimental fitment, the 90°-crossed twin-element set Yagi based single-mast-mounted array. Variants FuG 216: Experimental series to plan the further development. Installed in Fw 190 A-6/R11 and Bf 109 G-6 The aircraft were used by NJGr 10 until March 1944, after ...

Oberpfaffenhofen
Oberpfaffenhofen is a village that is part of the municipality of Weßling in the district of Starnberg, Bavaria, Germany. It is located about from the city center of Munich. Village The village is home to the Oberpfaffenhofen Airport and a major site of the German Aerospace Center (''Deutsches Zentrum für Luft- und Raumfahrt'', DLR). Oberpfaffenhofen became known to a wide audience when, in 1983, the first West-German astronaut, the physicist Ulf Merbold, flew to space onboard a Space Shuttle in a Spacelab mission. These missions were partly supervised by the German Space Operations Center located at Oberpfaffenhofen. The research center in Oberpfaffenhofen houses the DLR, including the Columbus Control Center which DLR operates for the European Space Agency and Airbus Defence and Space, and also some Fraunhofer Institutes and other scientific institutes. From 2014, OHB group moved the division which formerly was Kayser-Threde, from Munich to Oberpfaffenhofen. Also situa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Radars
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air bal ...

Dornier Do 335
The Dornier Do 335 ''Pfeil'' ("Arrow") was a heavy fighter built by Dornier for Germany during World War II. The two-seater trainer version was called ''Ameisenbär'' ("anteater"). The ''Pfeil''s performance was predicted to be better than other twin-engine designs due to its unique push-pull configuration and the lower aerodynamic drag of the in-line alignment of the two engines. It was Nazi Germany's fastest piston-engined aircraft of World War II. The ''Luftwaffe'' was desperate to get the design into operational use, but delays in engine deliveries meant that only a handful were delivered before the war ended. Design and development The origins of the Do 335 trace back to World War I when Claude Dornier designed a number of flying boats featuring remotely driven propellers and later, due to problems with the drive shafts, tandem engines. Tandem engines were used on most of the multi-engine Dornier flying boats that followed, including the highly successful Do J ''Wal'' and ...

Siemens & Halske
Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as ''Telegraphen-Bauanstalt von Siemens & Halske'' by Werner von Siemens and Johann Georg Halske. The company, located in Berlin-Kreuzberg, specialised in manufacturing electrical telegraphs according to Charles Wheatstone's patent of 1837. In 1848, the company constructed one of the first European telegraph lines from Berlin to Frankfurt am Main. Siemens & Halske was not alone in the realm of electrical engineering. In 1887, Emil Rathenau had established ''Allgemeine Elektrizitäts-Gesellschaft'' (AEG), which became a long-time rival. In 1881, Siemens & Halske built the Gross-Lichterfelde Tramway, the world's first electric streetcar line, in the southwestern Lichterfelde suburb of Berlin, followed by the Mödling and Hinterbrühl Tram near Vienna, the first electrical interurban tram in Austria-Hungary. 1882 saw the openi ...

Messerschmitt Me 262
The Messerschmitt Me 262, nicknamed ''Schwalbe'' (German: "Swallow") in fighter versions, or ''Sturmvogel'' (German: "Storm Bird") in fighter-bomber versions, is a fighter aircraft and fighter-bomber that was designed and produced by the German aircraft manufacturer Messerschmitt. It was the world's first operational jet-powered fighter aircraft. The initial design of what would become the Me 262 started in April 1939, prior to the start of the Second World War. While the aircraft performed its maiden flight on 18 April 1941, this was using piston engine instead of jet propulsion; it was not until 18 July 1942 that the first jet-powered flight was performed. Progress on the project was delayed by problems with engines, metallurgy and top-level interference from figures such as Hermann Göring, head of the Luftwaffe, and Adolf Hitler. The latter advocated from the Me 262 to be operated as a ground-attack/bomber aircraft rather than a defensive interceptor, thus necessitating a ...

Heinkel He 219
The Heinkel He 219 ''Uhu'' (" Eagle-Owl") is a night fighter that served with the German Luftwaffe in the later stages of World War II. A relatively sophisticated design, the He 219 possessed a variety of innovations, including Lichtenstein SN-2 advanced VHF-band intercept radar, also used on the Ju 88G and Bf 110G night fighters. It was also the first operational military aircraft to be equipped with ejection seats and the first operational German World War II-era aircraft with tricycle landing gear. Had the ''Uhu'' been available in quantity, it might have had a significant effect on the strategic night bombing offensive of the Royal Air Force; however, only 294 of all models were built by the end of the war and these saw only limited service.Boyne 1997, p. 330. Ernst-Wilhelm Modrow was the leading night fighter ace on the He 219. Modrow was credited with 33 of his 34 night air victories on the type.

Messerschmitt Bf 110
The Messerschmitt Bf 110, often known unofficially as the Me 110,Because it was built before ''Bayerische Flugzeugwerke'' became Messerschmitt AG in July 1938, the Bf 110 was never officially given the designation Me 110. is a twin-engine (Destroyer, heavy fighter), fighter-bomber (''Jagdbomber'' or ''Jabo''), and night fighter (''Nachtjäger'') developed in Nazi Germany in the 1930s and used by the Luftwaffe during World War II. Hermann Göring was a proponent of the Bf 110, believing its heavy armament, speed, and range would make the Bf 110 the Luftwaffe’s premier offensive fighter. Early variants were armed with two MG FF 20 mm cannon, four 7.92 mm (.312 in) MG 17 machine guns, and one 7.92 mm (.312 in) MG 15 machine gun for defence (later variants would replace the MG FFs with MG 151s and the rear gunner station would be armed with the twin-barreled MG 81Z). Development work on an improved type to replace the Bf 110 - the Messerschmitt Me 210 - began be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junkers Ju 88
The Junkers Ju 88 is a German World War II ''Luftwaffe'' twin-engined multirole combat aircraft. Junkers Aircraft and Motor Works (JFM) designed the plane in the mid-1930s as a so-called ''Schnellbomber'' ("fast bomber") that would be too fast for fighters of its era to intercept. It suffered from technical problems during its development and early operational periods but became one of the most versatile combat aircraft of the war. Like a number of other ''Luftwaffe'' bombers, it served as a bomber, dive bomber, night fighter, torpedo bomber, reconnaissance aircraft, heavy fighter and at the end of the war, as a flying bomb. Despite a protracted development, it became one of the ''Luftwaffe''s most important aircraft. The assembly line ran constantly from 1936 to 1945 and more than 15,000 Ju 88s were built in dozens of variants, more than any other twin-engine German aircraft of the period. Throughout production the basic structure of the aircraft remained unchanged.Angelucci a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Night Fighter
A night fighter (also known as all-weather fighter or all-weather interceptor for a period of time after the Second World War) is a fighter aircraft adapted for use at night or in other times of bad visibility. Night fighters began to be used in World War I and included types that were specifically modified to operate at night. During the Second World War, night fighters were either purpose-built night fighter designs, or more commonly, heavy fighters or light bombers adapted for the mission, often employing radar or other systems for providing some sort of detection capability in low visibility. Many night fighters of the conflict also included instrument landing systems for landing at night, as turning on the runway lights made runways into an easy target for opposing intruders. Some experiments tested the use of day fighters on night missions, but these tended to work only under very favourable circumstances and were not widely successful. Avionics systems were greatly mini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
