Sukhoi Su-17 (1949)
The Sukhoi Su-17 (Aircraft R) was a prototype Soviet fighter. The name was later reused for an entirely different fighter-bomber, see Sukhoi Su-17. Development The Su-17 was designed to closely match the theoretical TsAGI calculations for supersonic performance. The aircraft had a 50° swept wing A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigate ... fitted with air brakes and boosted controls. A unique feature was that in addition to an ejection seat, the entire nose section of the aircraft could separate from the rest of the airframe. The project was canceled with no flights due to problems with wing structure, ongoing difficulties with the development of the TR-3 engine, and the closure of the Sukhoi OKB. The only example was eventually used as a gunfire target. Specifications (S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Sukhoi Su-17
The Sukhoi Su-17 (''izdeliye'' S-32) is a variable-sweep wing fighter-bomber developed for the Soviet military. Its NATO reporting name is "Fitter". Developed from the Sukhoi Su-7, the Su-17 was the first variable-sweep wing aircraft to enter Soviet service. Two subsequent Sukhoi aircraft, the Su-20 and Su-22, have usually been regarded as variants of the Su-17. The Su-17/20/22 series has had a long career and has been operated by many other air forces of including the Russian Federation, other former Soviet republics, the former Warsaw Pact, countries in the Arab world, Angola and Peru. Development Shortly after the Su-7 fighter-bomber was put into service, the Sukhoi Design Bureau was ordered to develop a deep modernization program for the aircraft in the early 1960s. The program would be aimed primarily at updating on-board avionics and the takeoff/landing performance characteristics. The concept of variable-geometry wings - something gaining wider attention at that tim ... [...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 ...

Supersonic
Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swept Wing
A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of gravity ...

Air Brake (aircraft)
In aeronautics, air brakes or speed brakes are a type of flight control surface used on an aircraft to increase the drag on the aircraft. Air brakes differ from spoilers in that air brakes are designed to increase drag while making little change to lift, whereas spoilers reduce the lift-to-drag ratio and require a higher angle of attack to maintain lift, resulting in a higher stall speed. Introduction An air brake is a part of an aircraft. When extended into the airstream, it causes an increase in the drag on the aircraft. When not in use, it conforms to the local streamlined profile of the aircraft in order to help minimise the drag. History In the early decades of powered flight, air brakes were flaps mounted on the wings. They were manually controlled by a lever in the cockpit, and mechanical linkages to the air brake. An early type of air brake, developed in 1931, was fitted to the aircraft wing support struts. In 1936, Hans Jacobs, who headed Nazi Germany's '' ...

Lyulka TR-3
The Lyulka TR-3 was a Soviet axial turbojet designed after World War II by Arkhip Mikhailovich Lyulka. Development The Lyulka TR-3 was a single-shaft turbojet with a seven-stage axial compressor. It had an annular combustion chamber with 24 nozzles and a single-stage turbine. It had a fixed exhaust nozzle and had a pneumatic SV-3 starting unit, although this was later replaced by a turbine unit. It had a thrust of . It was used in the Ilyushin Il-30 during 1949, but was superseded by later versions. The improved TR-3A version was redesignated as the AL-5 to honor Lyulka in 1950.Kay, pp. 27–28 Applications * Ilyushin Il-30 * Sukhoi Su-17 (1949) The Sukhoi Su-17 (Aircraft R) was a prototype Soviet fighter.

Nudelman N-37 Cannon
The Nudelman N-37 was a 37 mm (1.46 in) aircraft autocannon used by the Soviet Union. It was designed during World War II by V. Ya. Nemenov of A.E. Nudelman's OKB-16 to replace the earlier Nudelman-Suranov NS-37 and entered service in 1946. It was 30% lighter than its predecessor at the cost of a 23% lower muzzle velocity. The N-37 was a sizable weapon firing a massive (735 g/26 oz HEI-T, 760 g/27 oz AP-T) shell. Its muzzle velocity was still considerable, but its rate of fire was only 400 rounds per minute. The weapon's considerable recoil and waste gases were problematic for turbojet fighter aircraft, as was finding space for the gun and a useful amount of ammunition, but a single shell was often sufficient to destroy a bomber. The N-37 was used in the MiG-9, MiG-15, MiG-17, and early MiG-19 fighters, the Yakovlev Yak-25, and others. Production lasted through the late 1950s, although it remained in service for many years afterwards. Variants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
