Tumansky R-21
The Tumansky R-21 was a Soviet turbojet engine of the 1960s. Used for development only, the project was canceled. Design and development The Tumansky R-21 was developed at Tushino motor plant (part of OKB-300), headed by Nikolai Georgievich Metskhvarishvili, as a twin-spool axial-flow afterburning turbojet. It was based on the Tumansky R-11 with the goal of increasing thrust and airflow, using a new six-stage compressor with a larger diameter and different rotor blades than its predecessor as well as a new afterburner chamber and variable exhaust nozzle. The increased pressure ratio and turbine inlet temperature required components to be fabricated from advanced alloys. Several contemporary Soviet aircraft were planned to use the R-21, including the Sukhoi T-58, Sukhoi T-6 and the Mikoyan-Gurevich Ye-8. On September 11, 1962 an R-21, fitted to a Ye-8, exploded in mid-air after compressor failure; test pilot Georgy Mosolov survived the ejection at Mach 1.78, but he never ful ...

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".

Sukhoi T-58
The Sukhoi Su-15 (NATO reporting name: Flagon) is a twinjet supersonic interceptor aircraft developed by the Soviet Union. It entered service in 1965 and remained one of the front-line designs into the 1990s. The Su-15 was designed to replace the Sukhoi Su-11 and Sukhoi Su-9, which were becoming obsolete as NATO introduced newer and more capable strategic bombers. Development Recognizing the limitations of the earlier Su-9 and Su-11 in intercepting the new Boeing B-52 Stratofortress, particularly in terms of radar and aircraft performance, the Sukhoi OKB quickly began the development of a heavily revised and more capable aircraft. A variety of development aircraft evolved, including the Sukhoi T-49, which shared the fuselage of the Su-9 (including its single engine), but used cheek-mounted intakes to leave the nose clear for a large radome for the RP-22 Oryol-D ("Eagle") radar (NATO "Skip Spin"), and the T-5, essentially a heavily modified Su-11 with a widened rear fuselage cont ...

Axial Compressor
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow compressors where the fluid flow will include a "radial component" through the compressor. The energy level of the fluid increases as it flows through the compressor due to the action of the rotor blades which exert a torque on the fluid. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. Compressors are typically driven by an electric motor or a steam or a gas turbine. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mikoyan-Gurevich MiG-23
The Mikoyan-Gurevich MiG-23 (russian: Микоян и Гуревич МиГ-23; NATO reporting name: Flogger) is a variable-geometry fighter aircraft, designed by the Mikoyan-Gurevich design bureau in the Soviet Union. It is a third-generation jet fighter, alongside similar Soviet aircraft such as the Su-17 "Fitter". It was the first Soviet fighter to field a look-down/shoot-down radar, the RP-23 Sapfir, and one of the first to be armed with beyond-visual-range missiles. Production started in 1969 and reached large numbers with over 5,000 aircraft built, making it the most produced variable-sweep wing aircraft in history. Today the MiG-23 remains in limited service with some export customers. The basic design was also used as the basis for the Mikoyan MiG-27, a dedicated ground-attack variant. Among many minor changes, the MiG-27 replaced the MiG-23's nose-mounted radar system with an optical panel holding a laser designator and a TV camera. Development The MiG-23's predec ...

Georgy Mosolov
Georgy Konstantinovich Mosolov (russian: Георгий Константинович Мосолов; 3 May 1926, in Ufa, Bashkortostan, Soviet Union – 18 March 2018) was a Soviet Russian test pilot. He attained the rank of ''Polkovnik'' (Colonel). He attained two world air speed records, in either the Mikoyan MiG-21 or the prototype Mikoyan Ye-66, as well as one altitude record. Colonel Mosolov was awarded the Hero of the Soviet Union The title Hero of the Soviet Union (russian: Герой Советского Союза, translit=Geroy Sovietskogo Soyuza) was the highest distinction in the Soviet Union, awarded together with the Order of Lenin personally or collectively for ... and the Lenin Prize. Mosolov set air speed records of on 31 October 1959 and and an altitude record of in a Ye-166 has in 1962.

Sukhoi T-6
The Sukhoi Su-24 (NATO reporting name: Fencer) is a supersonic, all-weather attack aircraft developed in the Soviet Union. The aircraft has a variable-sweep wing, twin-engines and a side-by-side seating arrangement for its crew of two. It was the first of the USSR's aircraft to carry an integrated digital navigation/attack system. It remains in service with the Russian Air Force, Syrian Air Force, Ukrainian Air Force, Algerian Air Force and various other air forces to which it was exported. Development Background One of the conditions for accepting the Sukhoi Su-7B into service in 1961 was the requirement for Sukhoi to develop an all-weather variant capable of precision air strikes. Preliminary investigations with ''S-28'' and ''S-32'' aircraft revealed that the basic Su-7 design was too small to contain all the avionics required for the mission. OKB-794 (later known as Leninets) was tasked with developing an advanced nav/attack system, codenamed ''Puma'', which would be at t ...

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 ...
