J-11D
The Shenyang J-11 (Chinese: 歼-11; NATO reporting name Flanker-B, -L) is a twin-engine jet fighter of the People's Republic of China whose airframe is derived from the Soviet-designed Sukhoi Su-27. It is manufactured by the Shenyang Aircraft Corporation (SAC). The aircraft is operated by the People's Liberation Army Air Force (PLAAF) and the People's Liberation Army Naval Air Force (PLANAF). Development Proposed J-11 In the 1970s, the PLAAF initiated a project to develop a replacement for its MiG-19s. The Shenyang Aircraft Factory proposal, designated J-11, was a new light fighter powered by the British Rolls-Royce Spey 512 engine, with better maneuverability than the MiG-19 and better climb rate than the MiG-21. The project was abandoned due to difficulties in obtaining the engines. Background: purchase of the Su-27 China is the first foreign operator of the Su-27 and the only country to acquire the fighter before the Fall of the Soviet Union. The deal, known as the '906 Pr ...

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 ...

MiG-19
The Mikoyan-Gurevich MiG-19 (russian: Микоян и Гуревич МиГ-19; NATO reporting name: Farmer) is a Soviet second generation, single-seat, twinjet fighter aircraft, the world's first mass-produced supersonic aircraft. It was the first Soviet production aircraft capable of supersonic speeds in level flight. A comparable U.S. "Century Series" fighter was the North American F-100 Super Sabre, although the MiG-19 primarily fought against the more modern McDonnell Douglas F-4 Phantom II and Republic F-105 Thunderchief over North Vietnam. This aircraft was originally used by the Soviet Union but it was later used by the People's Liberation Army Air Force. Design and development In 1950 the Mikoyan-Gurevich (MiG) design bureau (also known as OKB-155) began work on a new fighter aircraft, intended to have a greater range than the existing MiG-15 and MiG-17 aircraft, and capable of reaching supersonic speeds in level flight. MiG chose to use two of the new Mikulin AM-5 axi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flight Envelope
In aerodynamics, the flight envelope, service envelope, or performance envelope of an aircraft or spacecraft refers to the capabilities of a design in terms of airspeed and load factor or atmospheric density, often simplified to altitude. The term is somewhat loosely applied, and can also refer to other measurements such as maneuverability. When a plane is pushed, for instance by diving it at high speeds, it is said to be flown "outside the envelope", something considered rather dangerous. Flight envelope is one of a number of related terms that are all used in a similar fashion. It is perhaps the most common term because it is the oldest, first being used in the early days of test flying. It is closely related to more modern terms known as extra power and a doghouse plot which are different ways of describing a flight envelope. In addition, the term has been widened in scope outside the field of engineering, to refer to the strict limits in which an event will take place or mor ...

MiG-29
The Mikoyan MiG-29 (russian: Микоян МиГ-29; NATO reporting name: Fulcrum) is a twin-engine fighter aircraft designed in the Soviet Union. Developed by the Mikoyan design bureau as an air superiority fighter during the 1970s, the MiG-29, along with the larger Sukhoi Su-27, was developed to counter new U.S. fighters such as the McDonnell Douglas F-15 Eagle and the General Dynamics F-16 Fighting Falcon.Gordon and Davison 2005, p. 9. The MiG-29 entered service with the Soviet Air Forces in 1983. While originally oriented towards combat against any enemy aircraft, many MiG-29s have been furnished as multirole fighters capable of performing a number of different operations, and are commonly outfitted to use a range of air-to-surface armaments and precision munitions. The MiG-29 has been manufactured in several major variants, including the multirole Mikoyan MiG-29M and the navalised Mikoyan MiG-29K; the most advanced member of the family to date is the Mikoyan MiG-35.

Fall Of The Soviet Union
The dissolution of the Soviet Union, also negatively connoted as rus, Разва́л Сове́тского Сою́за, r=Razvál Sovétskogo Soyúza, ''Ruining of the Soviet Union''. was the process of internal disintegration within the Soviet Union (USSR) which resulted in the end of the country's and its federal government's existence as a sovereign state, thereby resulting in its constituent republics gaining full sovereignty on 26 December 1991. It brought an end to General Secretary Mikhail Gorbachev's (later also President) effort to reform the Soviet political and economic system in an attempt to stop a period of political stalemate and economic backslide. The Soviet Union had experienced internal stagnation and ethnic separatism. Although highly centralized until its final years, the country was made up of fifteen top-level republics that served as homelands for different ethnicities. By late 1991, amid a catastrophic political crisis, with several republics alread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
