Su-22
The Sukhoi Su-17 (''izdeliye'' S-32; NATO reporting name: Fitter) is a variable-sweep wing fighter-bomber developed for the Soviet Union, 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 Russia, 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 dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syrian Air Force
The Syrian Air Force () is the air force branch of the Syrian Armed Forces. It was established in 1948, and first saw action in the 1948 Arab–Israeli War. Under Ba'athist Syria until December 8, 2024, it was known as the Syrian Arab Air Force. Land-based air defense systems were grouped under the Syrian Air Defence Force, which split from both the Air Force and the Army. As of March 2025, the air force status is unknown, with some of its equipment being lost following the Hay'at Tahrir al-Sham and other rebel groups offensive in November 2024 and subsequent Israeli Air Force's airstrikes in December 2024, following the collapse of the Assad regime. History 1940s The end of World War II led to the withdrawal of the United Kingdom and France from the Middle East, and this included a withdrawal from Syria. In 1948, the Syrian Air Force was officially established after the first class of pilots graduated from a French-run flight school at Estabel airfield in Lebanon, usi ...

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).

Kh-25
The Kh-25/Kh-25M (; NATO: AS-10 'Karen) is a family of Soviet lightweight air-to-ground missiles with a modular range of guidance systems and a range of 10 km. The anti-radiation variant (Kh-25MP) is known to NATO as the AS-12 ' Kegler and has a range up to 40 km. Designed by Zvezda-Strela, the Kh-25 is derived from the laser-guided version of the Kh-23 Grom (AS-7 'Kerry'). The Kh-25 remains in widespread use despite the apparent development of a successor, the Kh-38. Development Based on an air-to-air missile, the beam-riding Kh-66 had been the Soviet Union's first air-to-ground missile for tactical aircraft, entering service in 1968. However it proved difficult to use in practice as the launch aircraft had to dive towards the target. A version with radio-command guidance, the Kh-23, was first tested in 1968 but problems with the guidance system meant that it would not enter service for another five years. So in 1971 work began on a version with a semi-active lase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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. Theoretically a Collective leadership in the Soviet Union, c ... [...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 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] |
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.

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 ...
