Klimov VK-3
The Klimov VK-3 was the first Soviet afterburning bypass turbojet engine. Designed by S V Lyunevich at Klimov, at OKB-117 in 1949, this engine first ran in 1952, and was qualified at thrust (dry) and thrust (with afterburner) in 1954. The VK-3 was developed for the Mikoyan-Gurevich I-3 (I-380) and I-3U/I-5 (I-410) fighters. First flown in the I-3U in July 1956, the engine's performances was good but its reliability was poor. Even after modifications in December 1956 when newly designed compressor blades were installed, developmental problems continued, the program was ultimately canceled in January 1958. The engine was superseded by the Lyulka AL-7F, a less modern but more efficient engine. Design The VK-3 is a single-shaft turbofan engine with a 10-stage axial compressor, an annular combustion chamber, a three-stage turbine, an afterburner and a variable supersonic nozzle. Bypass air is drawn from the second stage of the compressor to 12 external pipes and is directed into the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

Mikoyan-Gurevich I-3
The Mikoyan-Gurevich I-3 was the first of three interrelated fighter prototype programs developed by the Mikoyan-Gurevich design bureau in the Soviet Union in the mid/late 1950s – starting with the I-3, continuing with the I-7 and finally evolving into the I-75. On several occasions airframes were rebuilt and/or reused, both within a program or in a succeeding program. All the aircraft in the I-3 program were affected by delays in the development of the Klimov VK-3 afterburning bypass turbojet engine, and its cancellation and replacement by the Lyulka AL-7F turbojet engine. Design and development Both the I-3 and I-3P were ordered by the Council of Ministers on June 3, 1953 – the I-3 as a frontline fighter and the I-3P as an all-weather interceptor. They were developed in parallel with the I-1/2 program but had nothing in common with it except a similar wing. On the other hand, the I-3's visual appearance was so similar to the Sukhoi S-1 (the Su-7 prototype) that a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyulka AL-7
The Lyulka AL-7 was a turbojet designed by Arkhip Mikhailovich Lyulka and produced by his Lyulka design bureau. The engine was produced between 1954 and 1970.Gunston 1989, p.100. Design and development The AL-7 had supersonic airflow through the first stage of the compressor. TR-7 prototype, developing 6,500 kgf (14,330 lbf, 63.7 kN) of thrust, was tested in 1952, and the engine was initially intended for Ilyushin's Il-54 bomber. The afterburning AL-7F version was created in 1953. In April 1956, the Sukhoi S-1 prototype, equipped with the AL-7F, exceeded Mach 2 at 18,000 m (70,900 ft), which led to the production of the Su-7 'Fitter' and Su-9 'Fishpot', equipped with this engine.Green, William and Gordon Swanborough. ''The Great Book of Fighters.'' St. Paul, Minnesota: MBI Publishing, 2001. . Later, the engine was adopted for the Tu-128 'Fiddler' in 1960, and for the AS-3 'Kangaroo' cruise missile. The Beriev Be-10 jet flying boat used a non-afterburning AL-7PB with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pratt & Whitney TF30
The Pratt & Whitney TF30 (company designation JTF10A) is a military low-bypass turbofan engine originally designed by Pratt & Whitney for the subsonic F6D Missileer fleet defense fighter, but this project was cancelled. It was later adapted with an afterburner for supersonic designs, and in this form it was the world's first production afterburning turbofan, going on to power the F-111 and the F-14A Tomcat, as well as being used in early versions of the A-7 Corsair II without an afterburner. First flight of the TF30 was in 1964 and production continued until 1986. Design and development In 1958, the Douglas Aircraft Company proposed a short-range, four-engined jet airliner to fill the gap below its new DC-8 intercontinental, known internally as the Model 2067. Intended to be marketed as DC-9, it was not directly related to the later twin-engined Douglas DC-9.Connors 2010, p. 341 Pratt & Whitney (P&W) had offered its JT8A turbojet for the airliner, but Douglas preferred to go wi ...

Pratt & Whitney F100
The Pratt & Whitney F100 (company designation JTF22) is an afterburning turbofan engine manufactured by Pratt & Whitney that powers the F-15 Eagle and F-16 Fighting Falcon. Development In 1967, the United States Navy and United States Air Force issued a joint engine Request for Proposals (RFP) for the F-14 Tomcat and the FX, which became the parallel fighter design competition that led to the F-15 Eagle in 1970. This engine program was called the IEDP (Initial Engine Development Program) and was funded and managed out of the Aeronautical Systems Division (ASD) at Wright-Patterson AFB. Under ASD, a Systems Project Office Cadre was assigned to manage both the FX Aircraft and Engine definition phase. The Turbine Engine Division of the Air Force Propulsion Laboratory was employed in a support role to assist ASD Systems Engineering in evaluations of technical risks. Later upon selection of the F-15 the ASD engineering cadre became the F-15 Systems Project Office. The IEDP was creat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney PW1120
The Pratt & Whitney PW1120 turbofan is a derivative of the F100 turbofan. It was installed as a modification to a single F-4E fighter jet, and powered the canceled IAI Lavi. Development The development of the PW1120, according to Israeli Air Force (IDF/AF) specifications, started in June 1980. It retained the F100 core module, gearbox, fuel pump, forward ducts, as well as the F100 digital electronic control, with only minor modifications. Unique PW1120 components included a wide chord low pressure (LP) compressor, single-stage uncooled low pressure (LP) turbine, simplified single stream augmentor, and a lightweight convergent/divergent nozzle. Full scale testing was initiated in June 1982, and flight clearance of the PW1120 was tested in August 1984. The PW1120 had 70 percent similarity with the F100, so the IDF/AF would not need a special facility for spare parts. It would be built under licence by Bet-Shemesh Engines Limited in Israel. IAI installed one PW1120 in the starboa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric F110
The General Electric F110 is an afterburning turbofan jet engine produced by GE Aviation. The engine is derived from the General Electric F101 and shares its core design, and primarily powers tactical fighter aircraft. The F118 is a non-afterburning variant of the F110. The engine is also license-built in Eskisehir, Turkey by TUSAŞ Engine Industries (TEI). Design and development The F110 emerged from an intersection of efforts in the 1970s by General Electric to reenter the U.S. fighter engine market and the U.S. Air Force's desire to address the reliability, longevity, and maintenance issues with the Pratt & Whitney F100 engines that powered its F-15s and F-16s. In 1975, General Electric used its own funds to begin developing the F101X, a derivative of its F101 engine for the B-1 bomber; the F101X would inherit much of the core design while having a smaller fan so that its thermodynamic cycle and thrust was better suited for a fighter engine. The cancellation of the B-1A by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saturn AL-31
The Saturn AL-31 is a family of axial flow turbofan engines, developed by the Lyulka design bureau in the Soviet Union, now NPO Saturn in Russia, originally as a 12.5-tonne (122.6 kN, 27,560 lbf) powerplant for the Sukhoi Su-27 long range air superiority fighter. The AL-31 currently powers the Su-27 family of combat aircraft and some variants of the Chengdu J-10 multirole jet fighter. Assembly of the engine is also performed under license in India. Highly improved variants power the fifth-generation Sukhoi Su-57 and Chengdu J-20. Development and design The design of the AL-31 turbofan began in the 1970s under the designation ''izdeliye'' 99The Russian term , translit. ''izdeliye'' literally means "manufactured article" or "product". by the Lyulka design bureau, also known as Lyulka-Saturn. With an emphasis on greater fuel efficiency over turbojets for longer range, the class turbofan engine was intended to power the heavy PFI (russian: link=no, ПФИ, russian: link=no ...

Shenyang WS-10
The Shenyang WS-10 (), codename Taihang, is a turbofan engine designed and built by the People's Republic of China. Chinese media reported 266 engines were manufactured from 2010 to 2012 for the J-11 program. Unofficial estimates placed production at more than 300 units by May 2015. Description The WS-10A is advertised as an engine with thrust. It has full authority digital engine control (FADEC). Development The WS-10 is derived from the CFM56 with the experience gained from the Woshan WS-6 turbofan project, which was abandoned at the start of the 1980s. The WS-10 project was reportedly started by Deng Xiaoping in 1986 to produce an engine comparable to the Saturn AL-31. The work was given to the Shenyang Aeroengine Research Institute (606 Institute) of the Aviation Industry Corporation of China (AVIC). Initial production models suffered quality issues from the early direct use of AL-31 control systems. Furthermore, Salyut refused to sell source code of the full authorit ...
