Su-22 Fitter
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 time - ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Council Of Ministers Of The Soviet Union
The Council of Ministers of the Union of Soviet Socialist Republics ( rus, Совет министров СССР, r=Sovet Ministrov SSSR, p=sɐˈvʲet mʲɪˈnʲistrəf ɛsɛsɛˈsɛr; sometimes abbreviated to ''Sovmin'' or referred to as the ''Soviet of Ministers''), was the ''de jure'' government of the Union of Soviet Socialist Republics (USSR), comprising the main executive and administrative agency of the USSR from 1946 until 1991. During 1946 the Council of People's Commissars was reorganized as the Council of Ministers. Accordingly, the People's Commissariats were renamed as Ministries. The council issued declarations and instructions based on and in accordance with applicable laws, which had obligatory jurisdictional power in all republics of the Union. However, the most important decisions were made by joint declarations with the Central Committee of the Communist Party of Soviet Union (CPSU), which was ''de facto'' more powerful than the Council of Ministers.

Central Committee Of The Communist Party Of The Soviet Union
The Central Committee of the Communist Party of the Soviet Union, – TsK KPSS was the executive leadership of the Communist Party of the Soviet Union, acting between sessions of Congress. According to party statutes, the committee directed all party and governmental activities. Its members were elected by the Party Congress. During Vladimir Lenin's leadership of the Communist Party, the Central Committee functioned as the highest party authority between Congresses. However, in the following decades the ''de facto'' most powerful decision-making body would oscillate back and forth between the Central Committee and the Political Bureau or Politburo (and during Joseph Stalin, the Secretariat). Some committee delegates objected to the re-establishment of the Politburo in 1919, and in response, the Politburo became organizationally responsible to the Central Committee. Subsequently, the Central Committee members could participate in Politburo sessions with a consultative voic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stall (fluid Dynamics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller thr ...

Angle Of Attack
In fluid dynamics, angle of attack (AOA, α, or \alpha) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow. This article focuses on the most common application, the angle of attack of a wing or airfoil moving through air. In aerodynamics, angle of attack specifies the angle between the chord line of the wing of a fixed-wing aircraft and the vector representing the relative motion between the aircraft and the atmosphere. Since a wing can have twist, a chord line of the whole wing may not be definable, so an alternate reference line is simply defined. Often, the chord line of the root of the wing is chosen as the reference line. Another choice is to use a horizontal line on the fuselage as the reference line (and also as the longitudinal axis). Some aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeroelasticity
Aeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow. The study of aeroelasticity may be broadly classified into two fields: ''static aeroelasticity'' dealing with the static or steady state response of an elastic body to a fluid flow; and ''dynamic aeroelasticity'' dealing with the body's dynamic (typically vibrational) response. Aircraft are prone to aeroelastic effects because they need to be lightweight and withstand large aerodynamic loads. Aircraft are designed to avoid the following aeroelastic problems: # divergence where the aerodynamic forces increase the angle of attack of a wing which further increases the force; # control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases, reverses the control effectiveness; and # flutter which is the uncontained vibration that can lead ...

Domodedovo (town)
Domodedovo ( rus, Домодедово, p=dəmɐˈdʲedəvə) is a city in Moscow Oblast, Russia, located south of Moscow. Population: The increase of population is due to the merger of three neighboring inhabited localities into the town in 2004. Geography The town is located on the Moskva-Oka plain, in the center of the East European Plain, south-east of the capital, 37 km from the center of Moscow, on the Moscow – Kashira highway and the Paveletsky suburban railway line, near the federal highway, M-4 "Don". Most of the town is located to the west of the railway line. The town stretches from north to south along the railroad tracks on 26 kilometers. The climate is moderate continental, with cold, snowy winters, and warm, humid summers. The frequent passage of cyclones from the Atlantic and the Mediterranean sometimes causes an increase in cloud cover. Average mid-January temperature is about −10,5 °C, and mid-July is +17,5 °C. The average duration of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vladimir Ilyushin
Vladimir Sergeyevich Ilyushin (russian: Владимир Серге́евич Ильюшин; 31 March 1927 – 1 March 2010) was a Soviet general and test pilot, and the son of aerospace engineer Sergey Ilyushin. He spent most of his career as a test pilot for the Sukhoi OKB (a rival of Ilyushin OKB). Ilyushin was also a rugby union administrator who was inducted into the World Rugby Hall of Fame (then known as the IRB Hall of Fame) in 2013. In 1961, Ilyushin was the subject of a conspiracy theory that he, rather than Yuri Gagarin, was the first cosmonaut in space. There is no evidence and no support to the theory. Career as test pilot Ilyushin was a test pilot and lieutenant general in the Soviet Air Forces. He piloted the maiden flights of the Sukhoi's Su-11 (1958), Т-5 (1958), Su-15 (1962), Su-17 (1966), Su-24 (1967), Т-4 (1972), Su-25 (1975) and the Su-27 (1977). Ilyushin demonstrated his outstanding piloting skills as a test pilot of the Sukhoi Su-24. He flew a cours ... [...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 ...
