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, aft ...

Aircraft Radars
An aircraft ( 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 the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." 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, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dornier Do 335
The Dornier Do 335 ''Pfeil'' (Arrow) is a heavy fighter built by Dornier for Germany during World War II. The ''Pfeil''s performance was predicted to be better than other twin-engine designs due to its unusual push-pull configuration and the lower aerodynamic drag of the in-line alignment of the two engines. It is considered one of the fastest piston-engined aircraft ever and 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. The Do 335 was originally designed as a Schnellbomber. It could reach speeds of around 800 km/h in level flight, and could outrun most of the military aircraft in service at the time, with only first generation jet fighters being faster. Design and development The origin of the Do 335 goes back to World War I when Claude Dornier designed a number of flying boats with tand ...

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 o ...

Messerschmitt Me 262
The Messerschmitt Me 262, nicknamed (German for "Swallow") in fighter versions, or ("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 and one of two jet fighter aircraft types to see air-to-air combat in World War Two, the other being the Heinkel He 162. The design of what would become the Me 262 started in April 1939, before World War II. It made its maiden flight on 18 April 1941 with a piston engine, and its first jet-powered flight on 18 July 1942. Progress was delayed by problems with engines, metallurgy Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys.

Heinkel 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 pressurized cockpit, twin ejection seats and remotely controlled defensive gun turrets. The P.1055 was initially rejected by the ''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 SN-2 advanced VHF-band intercept radar (also used on the Ju 88G and Bf 110G night fighters). The He 219 was also the first operational military aircraft to be equipped with ejection seats and the first operational German aircraft to be equipped with tricyc ...

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-engined (destroyer, heavy fighter), fighter-bomber (''Jagdbomber'' or ''Jabo''), and night fighter (''Nachtjäger'') designed by the German aircraft company Bayerische Flugzeugwerke (BFW) and produced by successor company Messerschmitt. It was primarily operated by the ''Luftwaffe'' and was active throughout the Second World War. Development of the Bf 110 commenced during the first half of the 1930s; one early proponent of the type was Hermann Göring, who believed its heavy armament, speed, and range would make it the premier offensive fighter of the ''Luftwaffe''. Early variants were armed with a pair of MG FF 20 mm cannon, four 7.92 mm (.323 in) MG 17 machine guns, and one 7.92 mm (.323 in) MG 15 machine gun for defence (late ...

Junkers Ju 88
The Junkers Ju 88 is a twin-engined multirole combat aircraft designed and produced by the German aircraft manufacturer Junkers Aircraft and Motor Works. It was used extensively during the Second World War by the ''Luftwaffe'' and became one of the most versatile combat aircraft of the conflict. The Ju 88 originated from a ''Reichsluftfahrtministerium'' (RLM) requirement issued in 1934 for a new multipurpose aircraft. Junkers was one of several firms to respond, producing two separate design studies that produced both the Ju 85 and Ju 88. The design work was headed by Junkers' chief designer Ernst Zindel. The Ju 88 was envisioned to function as a so-called '' Schnellbomber'' ("fast bomber") that would evade interception by enemy fighters of its era by flying at high speed. On 21 December 1936, the first prototype performed its maiden flight. The performance of the third prototype was highly favourable, resulting in the competing Henschel Hs 127 and Messerschmitt Bf 162 bein ...

Night Fighter
A night fighter (later known as all-weather fighter or all-weather interceptor post-Second World War) is a largely historical term for a fighter aircraft, fighter or interceptor aircraft adapted or designed for effective use at night, during periods of adverse meteorological conditions, or in otherwise poor visibility. Such designs were in direct contrast to day fighter, day fighters: fighters and interceptors designed primarily for use during the day or during good weather. The concept of the night fighter was developed and experimented with during the First World War but would not see widespread use until WWII. The term would be supplanted by “all-weather fighter/interceptor” post-WWII, with advancements in various technologies permitting the use of such aircraft in virtually all conditions. 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 ...
