Su-20
The Sukhoi Su-17 (''izdeliye'' S-32; NATO reporting name: Fitter) is a variable-sweep wing fighter-bomber developed for the Soviet military. Developed from the Sukhoi Su-7, the Su-17 was the first variable-sweep wing aircraft to enter Soviet service and featured updated avionics. The aircraft also has variants which were designed to be exported to non-Soviet states such as the Sukhoi Su-22 and the less popular Su-20. It was produced from 1967 to 1990. The Su-17/20/22 series had a long career and has been operated by many air forces, including those of the Russian Federation, former Soviet republics, former Warsaw Pact, countries in the Arab world, Angola, and Peru. The Russian Federation retired its fleet in 1998. Although the Su-17 was capable of carrying nuclear weapons, it was used in roles ranging from close-air support to ground attack. Development Shortly after the Su-7 fighter-bomber was put into service, the Sukhoi Design Bureau was ordered to develop a modernization ...

Polish Air Force
The Polish Air Force () is the aerial warfare Military branch, branch of the Polish Armed Forces. Until July 2004 it was officially known as ''Wojska Lotnicze i Obrony Powietrznej'' (). In 2014 it consisted of roughly 26,000 military personnel and about 475 aircraft, distributed among ten bases throughout Poland. The Polish Air Force can trace its origins to the second half of 1917 and was officially established in the months following the end of World War I in 1918. During the invasion of Poland by Nazi Germany in 1939, 70% of its aircraft were destroyed. Most pilots, after the Soviet invasion of Poland on 17 September, escaped via Romania and Hungary to continue fighting throughout World War II in allied air forces, first in France, then in Britain, and later also the Soviet Union. History Polish Air Force backline Origins Military aviation in Poland started even before the officially recognised date of regaining independence (11 November 1918). The first independent units of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sukhoi Su-7
The Sukhoi Su-7 ( NATO designation name: Fitter-A) is a swept wing, supersonic fighter aircraft developed by the Soviet Union in 1955. Originally, it was designed as a tactical, low-level dogfighter, but was not successful in this role. On the other hand, the soon-introduced Su-7B series became the main Soviet fighter-bomber and ground-attack aircraft of the 1960s. The Su-7 was rugged in its simplicity, but its Lyulka AL-7 engine had such high fuel consumption that it seriously limited the aircraft's payload, as even short-range missions required that at least two hardpoints be used to carry drop tanks rather than ordnance. Design and development After Joseph Stalin's death, the Sukhoi OKB was reopened"Sukhoi Su-7." ''Sukhoi Company Museum.'' Retrieved: 28 January 2011 and by the summer, it began work on a swept-wing front-li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

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 ˌɛsˌɛsˌɛsˈɛr), sometimes abbreviated as 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 was the Central committee, highest organ of the Communist Party of the Soviet Union (CPSU) between Congress of the Communist Party of the Soviet Union, Congresses. Elected by the Congress, the Central Committee emerged as the core nexus of executive and administrative authority in the party, with de facto supremacy over the government of Russian Soviet Federative Socialist Republic, Soviet Russia and the Soviet Union. It was composed of full members and candidate (non-voting) members. Real authority was often concentrated in smaller, more agile organs elected by the Committee, namely the Politburo of the Communist Party of the Soviet Union, Politburo, Secretariat of the Communist Party of the Soviet Union, Secretariat, and Orgburo (dissolved in 1952), as well as in the post of General Secretary of the Communist Party of the Soviet Union, General Secretary.

Stall (fluid Dynamics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil – including its shape, size, and finish – and Reynolds number. Stalls in fixed-wing aircraft are often experienced as a sudden reduction in lift. It may be caused either by the pilot increasing the wing's angle of attack or by a decrease in the critical angle of attack. The former may be due to slowing down (below stall speed), the latter by accretion of ice on the wings (especially if the ice is rough). 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 al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Angle Of Attack
In fluid dynamics, angle of attack (AOA, α, or \alpha) is the angle between a Airfoil#Airfoil terminology, reference line on a body (often the chord (aircraft), chord line of an airfoil) and the vector (geometry), 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 Wing root, root of the wing is chosen as the reference line. Another choice is to use a horizontal line on the fuse ...

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 while enduring large aerodynamic loads. Aircraft are designed to avoid the following aeroelastic problems: # divergence where the aerodynamic forces increase the twist of a wing which further increases forces; # control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases reverses, the control effectiveness; and # flutter which is uncontained vibration that can lead to the destr ...

Domodedovo (town)
Domodedovo (, ) is a city in Moscow Oblast, Russia, located south of the capital Moscow. The population estimated in different years are . 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Vladimir Ilyushin
Vladimir Sergeyevich Ilyushin (; 31 March 1927 – 1 March 2010) was a Russian military officer and a test pilot in the former Soviet space program. Ilyushin was a son of the famous aviation designer Sergey Ilyushin, and whose career was mostly as a test pilot for the Sukhoi OKB (a rival of Ilyushin OKB). After retiring from the space program, Ilyushin became a sports administrator and 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 for 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).
