Messerschmitt Me 262A-1
The Messerschmitt Me 262 was a German World War II fighter aircraft built by Messerschmitt in the later stages of the war, and under license by Avia post-war. Prototypes Messerschmitt began work on a single-seat jet-powered fighter before the start of World War II. The initial design was known as ''Projekt'' 1070 (P.1070). A twin-engined straight-wing design, the P.1070 was canceled in favor of the similar P.65. The P.65 was designed with a straight wing, similar to the P.1070, as well as an unswept vertical stabilizer. The prototypes were to be powered by two BMW 003 (P.3302) turbojet engines, while production aircraft would have had two BMW P.3304 engines. Messerschmitt later redesigned the P.65 with swept wings and tail surfaces as the P.1065, which was to have conventional landing gear and be armed with three MG 151 cannons with 250 rounds each. As of July 1940, the RLM ordered 20 prototypes of the P.1065 and planned to take delivery of the first aircraft by Septe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messerschmitt Me 262 050606-F-1234P-055
Messerschmitt AG () was a German share-ownership limited, aircraft manufacturing corporation named after its chief designer Willy Messerschmitt from mid-July 1938 onwards, and known primarily for its World War II fighter aircraft, in particular the Bf 109 and Me 262. The company survived in the post-war era, undergoing a number of mergers and changing its name from Messerschmitt to Messerschmitt-Bölkow-Blohm before being bought by Deutsche Aerospace (DASA, now part of Airbus) in 1989. History Background In February 1916, the south German engineering company MAN AG and several banks purchased the unprofitable aircraft builder Otto-Flugzeugwerke, starting a new company, ''Bayerische Flugzeugwerke AG'' (abbreviated ''B.F.W.''). The articles of association were drawn up on 19 and 20 February, and completed on 2 March 1916. Details of the company were recorded in the Commercial Register with an equity capital of RM 1,000,000 on 7 March 1916. 36% of the capital was provided ...

Tricycle Landing Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172. Their marketing department described this as "Land-O-Matic" t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MK 214A Cannon
The MK 214A was a calibre auto-cannon designed by Mauser Werke AG, for use on Messerschmitt Me 262 and Messerschmitt Me 410, Me 410 bomber-destroyers. Intended for use on the Messerschmitt Me 262A-1a/U4, Mauser designed the MK 214, derived from the 5 cm Pak 38 anti-tank gun. Initial trials with the MK 214 revealed it to be over-complicated, so a refined version was developed as the MK 214A, flight tests of which were carried out from February 1945 by Karl Baur, but the weapon was not deployed operationally. A similar installation using the BK 5 cannon was also planned. References [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bistatic Radar
Bistatic radar is a radar system comprising a transmitter and receiver that are separated by a distance comparable to the expected target distance. Conversely, a conventional radar in which the transmitter and receiver are co-located is called a monostatic radar. A system containing multiple spatially diverse monostatic or bistatic radar components with a shared area of coverage is called ''multistatic radar''. Many long-range air-to-air and surface-to-air missile systems use semi-active radar homing, which is a form of bistatic radar. Types Pseudo-monostatic radars Some radar systems may have separate transmit and receive antennas, but if the angle subtended between transmitter, target and receiver (the bistatic angle) is close to zero, then they would still be regarded as monostatic or pseudo-monostatic. For example, some very long range HF radar systems may have a transmitter and receiver which are separated by a few tens of kilometres for electrical isolation, but as ...

Lichtenstein Radar
The Lichtenstein radar was among the earliest airborne radars available to the Luftwaffe in World War II and the first one used exclusively for air interception. Developed by Telefunken, it was available in at least four major revisions, called FuG 202 Lichtenstein B/C, FuG 212 Lichtenstein C-1, FuG 220 Lichtenstein SN-2 and the very rarely used FuG 228 Lichtenstein SN-3. (FuG is short for ''Funk-Gerät'', radio set). The Lichtenstein series remained the only widely deployed airborne interception radar used by the Germans on their night fighters during the war — the competing FuG 216 through 218 ''Neptun'' mid- VHF band radar systems were meant as a potentially more versatile stop-gap system through 1944, until the microwave-based FuG 240 "Berlin" could be mass-produced; the ''Berlin'' system was still being tested when the war ended. FuG 202 Lichtenstein B/C Early FuG 202 Lichtenstein B/C units were not deployed until 1942. They operated at a maximum RF output power o ...

MK 103 Cannon
The Rheinmetall-Borsig MK 103 ("MK" - '' Maschinenkanone'') was a German 30 mm caliber autocannon that was mounted in German combat aircraft during World War II. Intended to be a dual purpose weapon for anti-tank and air-to-air fighting, it was developed from the MK 101. Compared to the MK 101 it was faster firing, and was originally intended to develop a higher muzzle velocity than the MK 101. Unlike the MK 101, the MK 103 used a belt feed, allowing it to potentially carry a larger ammunition load. The MK 103 used electrically primed rather than percussion-primed ammunition. The operating mechanism differed from the recoil-operated MK 101 in that it used a combination of gas and recoil operation. After firing, gas pressure served to unlock the breech, while barrel recoil was used to cycle the action (eject spent cartridge and load a fresh one). Because of a combination of lower grade steels and lighter components, the mechanism of the MK 103 was not as strong as the MK 101. To cou ...

Swallow
The swallows, martins, and saw-wings, or Hirundinidae, are a family of passerine songbirds found around the world on all continents, including occasionally in Antarctica. Highly adapted to aerial feeding, they have a distinctive appearance. The term "swallow" is used colloquially in Europe as a synonym for the barn swallow. Around 90 species of Hirundinidae are known, divided into 19 genus, genera, with the greatest diversity found in Africa, which is also thought to be where they evolved as hole-nesters. They also occur on a number of oceanic islands. A number of European and North American species are long-distance bird migration, migrants; by contrast, the West and South African swallows are nonmigratory. This family comprises two subfamilies: Pseudochelidoninae (the river martins of the genus ''Pseudochelidon'') and Hirundininae (all other swallows, martins, and saw-wings). In the Old World, the name "martin" tends to be used for the squarer-tailed species, and the name "swal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rechlin–Lärz Airfield
Rechlin–Lärz Airfield (German: ''Flugplatz Rechlin-Lärz'') is an airfield in the village of Rechlin, Mecklenburg-Western Pomerania, Germany. The airport is not used for scheduled traffic but features general aviation and is home to other leisure activities as well. Additionally, the music festival Fusion Festival takes place here. History The airport was once part of the Third Reich era's Luftwaffe main testing ground, or ''Erprobungsstelle'' for new aircraft designs, the heart of which was actually centered on two large turf areas some due north (at ) of the 21st century era paved-runway airport facility. The core airfield of the Luftwaffe facility took the form of a typical pre-World War II aerodrome, with no clearly defined "runways", being bounded ba roughly hexagonal-layout perimeter roadthat still exists today, defining an area approximately across within it of about 234.3 hectares, or 578.9 acres, which today is the site of the annual Fusion music festival.

BMW 109-718
The BMW 109-718 was a liquid-fuelled rocket engine developed by BMW at their Bruckmühl facility, in Germany during the Second World War. Development The 109-718 (109 prefix number for the ''Reichsluftfahrtministerium'', or ''RLM'', designation used for all reaction-propulsion ocket and gas turbineaviation engine projects) was designed as an assist rocket for aircraft, for rapid takeoffs or to enable them to achieve high-speed sprints, akin to what Americans called "mixed power" postwar. It was combined with a standard BMW 003 jet engine, placed atop the rear turbine casing of the jet engine to create a new variant of it, the 003R, providing a total of thrust at full power apiece; it was expected the units would be fitted in pairs. Unlike most RATO boosters, the liquid-fuelled 718 rocket engine system comprising the second propulsive source of an 003R engine remained with the airframe at all times. The rocket motor had internal and external main chambers which were cooled b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter HWK 109-509
The Walter HWK 109-509 was a German liquid-fuel bipropellant rocket engine that powered the Messerschmitt Me 163 Komet and Bachem Ba 349 aircraft. It was produced by Hellmuth Walter Kommanditgesellschaft (HWK) commencing in 1943, with licensed production by the Heinkel firm's facilities in Jenbach, Austria. Design and development Early versions of the Me 163 had been powered by an earlier design running on a "cold engine" fueled with Z-Stoff. This fuel tended to clog the jets in the combustion chamber, causing fluctuations in power and potentially explosions. Worse, however, was the fact that the engine could not be throttled, and when the aircraft leveled off after its climb to altitude it quickly accelerated to speeds that caused serious compressibility issues. The RLM demanded that a version be developed with a throttle. During this period Walter had also been working with a new fuel known as C-Stoff that gave off significant heat and was thus known as the "hot engine". ...

Solid-propellant Rocket
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses Rocket propellant#Solid chemical propellants, solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were used in warfare by the Mamluk Sultanate, Arabs, Dynasties in Chinese history, Chinese, Ilkhanate, Persians, Mongol Empire, Mongols, and Delhi Sultanate, Indians as early as the 13th century. All rockets used some form of solid or powdered propellant up until the 20th century, when liquid-propellant rockets offered more efficient and controllable alternatives. Solid rockets are still used today in military armaments worldwide, model rockets, solid rocket boosters and on larger applications for their simplicity and reliability. Since solid-fuel rockets can remain in storage for an extended period without much propellant degradation and because they almost always launch reliably, they have been frequently used in military applications such as ...
