OKB-1 EF 131
The OKB-1/Junkers EF 131 was a jet bomber produced in Germany and the USSR from 1944. Development The EF-131 was developed based on fragments of project documentation for the Ju 287 after the Red Army captured the Junkers factory in Dessau. The first prototype was built from components of the Junkers Ju 287 V2 and V3, the second and third prototypes (V – Versuchs – test/research/prototype) of the Luftwaffe's radical forward-swept-wing jet bomber. The V2 was nearly complete before the end of World War 2, but was hidden in the forest at Brandis along with Ju 287 V1 and eventually blown up by the Germans to avoid capture by US forces, and remnants of it, including wing sections, were taken into Red Air Force hands under military intelligence supervision along with the skeletal airframe of the unfinished V3.Lommel, Horst, 2004.

Air Show
An air show (or airshow, air fair, air tattoo) is a public event where aircraft are exhibited. They often include aerobatics demonstrations, without they are called "static air shows" with aircraft parked on the ground. The largest air show measured by number of exhibitors and size of exhibit space is Le Bourget followed by Farnborough, while Dubai air show and Singapore Air Show are both claiming the third place. The largest air show or fly-in by number of participating airplanes is EAA AirVenture Oshkosh, commonly known as "Oshkosh" after its location in Wisconsin, with approximately 10,000 airplanes participating each year. The biggest military airshow in the world is the Royal International Air Tattoo, at RAF Fairford in England. Outline Some airshows are held as a business venture or as a trade event where aircraft, avionics and other services are promoted to potential customers. Many air shows are held in support of local, national or military charities. Military ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s German Bomber Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria. Pescennius retreats to Antioch, and is executed by Severus' troops. * Septimius Severus besieges Byzantium (194–196); the city walls suffer extensive damage.

Martin XB-51
The Martin XB-51 was an American trijet ground-attack aircraft. It was designed in 1945 and made its maiden flight in 1949. It was originally designed as a bomber for the United States Army Air Forces under specification V-8237-1 and was designated XA-45. The "A" ground-attack classification was eliminated the next year, and the XB-51 designation was assigned instead. The requirement was for low-level bombing and close support. The XB-51 lost out in evaluation to the English Electric Canberra which - built by Martin - entered service as the Martin B-57 Canberra. Design and development This unorthodox design, first flying on 28 October 1949, was fitted with three General Electric J47 engines - an unusual number for a combat aircraft - two underneath the forward fuselage in pods, and one at the extreme tail with the intake at the base of the tailfin. The innovative, variable incidence wings, swept at 35° and with 6° anhedral, were equipped with leading edge slats and full- ...

Martin XB-48
The Martin XB-48 was an American medium jet bomber developed in the mid-1940s. It competed with the Boeing B-47 Stratojet, which proved to be a superior design, and was largely considered as a backup plan in case the B-47 ran into development problems. It never saw production or active duty, and only two prototypes, serial numbers 45-59585 and 45-59586, were built. Design and development In 1944, the U.S. War Department was aware of aviation advances in Germany and issued a requirement for a range of designs for medium bombers weighing from to more than . Other designs resulting from this competition, sometimes nicknamed "The Class of 45", included the North American XB-45 and the Convair XB-46. Production orders finally went to the North American B-45 Tornado, and even this airplane served only for a couple of years before again being replaced by the much more modern Boeing B-47 Stratojet, although the B-45 had the inherent performance – especially if it was not burdened wi ...

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 ...

Junkers Motoren Jumo 109-004
The Junkers Jumo 004 was the world's first production turbojet engine in operational use, and the first successful axial compressor turbojet engine. Some 8,000 units were manufactured by Junkers in Germany late in World War II, powering the Messerschmitt Me 262 fighter and the Arado Ar 234 reconnaissance/bomber, along with prototypes, including the Horten Ho 229. Variants and copies of the engine were produced in Eastern Europe and the USSR for several years following the end of WWII. Design and development The feasibility of jet propulsion had been demonstrated in Germany in early 1937 by Hans von Ohain working with the Heinkel company. Most of the Reich Air Ministry ( RLM) remained uninterested, but Helmut Schelp and Hans Mauch saw the potential of the concept and encouraged Germany's aero engine manufacturers to begin their own programmes of jet engine development. The companies remained skeptical and little new development was carried out. In 1939 Schelp and Mauch visited th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TsAGI
The Central Aerohydrodynamic Institute (also (Zhukovsky) Central Institute of Aerodynamics, russian: Центра́льный аэрогидродинами́ческий институ́т, ЦАГИ, Tsentral'nyy Aerogidrodinamicheskiy Institut, TsAGI) was founded in Moscow by Russian aviation pioneer Nikolai Yegorovich Zhukovsky on December 1, 1918. History From 1925 and up to the 1930s, TsAGI developed and hosted Tupolev's AGOS (''Aviatziya, Gidroaviatziya i Opytnoye Stroitelstvo'', the "Aviation, Hydroaviation, and Experimental Construction"), the first aircraft design bureau in Soviet Union, and at the time the main one. In 1930, two other major aircraft design bureaus in the country were the Ilyushin's TsKB (''Tsentralnoye Konstruksionnoye Byuro'' means "Central Design Bureau") and an independent, short-lived Kalinin's team in Kharkiv. In 1935 TsAGI was partly relocated to the former dacha settlement ''Otdykh'' (literally, "Relaxation") converted to the new urban-type set ...
