Pratt & Whitney PW2000
The Pratt & Whitney PW2000, also known by the military designation F117 and initially referred to as the JT10D, is a series of high-bypass turbofan aircraft engines with a thrust range from . Built by Pratt & Whitney, they were designed for the Boeing 757. As a 757 powerplant, these engines compete with the Rolls-Royce RB211. Design and development Pratt & Whitney began working on the JT10D in October 1971 intended for the McDonnell Douglas YC-15 into the Advanced Medium STOL Transport project and the Boeing 767, then code named 7X7, which first ran in August 1974. In December 1980, Pratt & Whitney changed to a new naming system for its engines and the JT10D became the PW2037. The PW2000 is a dual-spool, axial air flow, annular combustion, high bypass turbofan with a dual-channel Full authority digital engine control (FADEC) system. It was certified in 1984 as the first civilian FADEC-controlled aviation engine. MTU Aero Engines holds a 21.2% stake in the engine, having d ...

Pratt & Whitney PW1000G
The Pratt & Whitney PW1000G, also called the Geared Turbofan (GTF), is a high-bypass geared turbofan engine family produced by Pratt & Whitney. After many demonstrators, the program was launched with the Mitsubishi MRJ's PW1200G in March 2008, and it was first flight tested in July 2008. The first variant to be certified was the PW1500G for the Airbus A220 in February 2013. The program cost is estimated at $10 billion. The gearbox between the fan and the low-pressure spool allows each to spin at its optimal speed, allowing a higher bypass ratio for a better propulsive efficiency. Pratt & Whitney claims the engine is 16% more fuel efficient than the previous generation, and up to 75% quieter. The first variant to enter service was the PW1100G for the A320neo in January 2016. The engine had teething problems after its introduction, extending to grounded aircraft and inflight failures, solved afterwards. The variants can generate 15,000 to 33,000 lbf (67 to 147 kN) of thrust. Be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CFM International CFM56
The CFM International CFM56 (U.S. military designation F108) series is a Franco-American family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of . CFMI is a 50–50 joint-owned company of Safran Aircraft Engines (formerly known as Snecma) of France, and GE Aviation (GE) of the United States. Both companies are responsible for producing components and each has its own final assembly line. GE produces the high-pressure compressor, combustor, and high-pressure turbine, Safran manufactures the fan, gearbox, exhaust and the low-pressure turbine, and some components are made by Avio of Italy and Honeywell from the US. The engines are assembled by GE in Evendale, Ohio, and by Safran in Villaroche, France. The completed engines are marketed by CFMI. Despite initial export restrictions, it is the most used turbofan aircraft engine in the world, in four major variants. The CFM56 first ran in 1974.Bilien, J. and Matta, R. (1989). ''T ...

General Electric CF6
The General Electric CF6, US military designations F103 and F138, is a family of high-bypass turbofan engines produced by GE Aviation. Based on the TF39, the first high-power high-bypass jet engine, the CF6 powers a wide variety of civilian airliners. The basic engine core also powers the LM2500 and LM6000 marine and power generation turboshafts. It is gradually being replaced by the newer GEnx family. Development After developing the TF39 for the C-5 Galaxy in the late 1960s, GE offered a more powerful variant for civilian use, the CF6, and quickly found interest in two designs being offered for a recent Eastern Airlines contract, the Lockheed L-1011 and the McDonnell Douglas DC-10. Lockheed eventually selected the Rolls-Royce RB211, but the latter stuck with the CF6 and entered service in 1971. It was also selected for versions of the Boeing 747. Since then, the CF6 has powered versions of the Airbus A300, A310 and A330, Boeing 767, and McDonnell Douglas M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric CF34
The General Electric CF34 is a civilian high-bypass turbofan developed by GE Aircraft Engines from its TF34 military engine. The CF34 is used on a number of business and regional jets, including the Bombardier CRJ series, the Embraer E-Jets, and Comac ARJ21. In 2012, there were 5,600 engines in service. Design and development The original engine contained a single stage fan driven by a 4-stage low pressure (LP) turbine, supercharging a 14-stage HP compressor driven by a 2-stage high pressure (HP) turbine, with an annular combustor. Later higher thrust versions of the CF34 feature an advanced technology core, with only 10 HP compressor stages. Latest variants, the and , were derived from the CFM56 engine family, and have a radically different HP spool, containing a 9-stage compressor driven by a single stage turbine. The LP spool has 3 core booster stages behind the fan. Static thrust is for the variant. On wing times can reach 14,000 hours, an overhaul costs over ...

Design and development BR710 The BR710 is a twin shaft turbofan, and entered service on the Gulfstream V in 1997 and the Bombardier Global Express in 1998. This version has also been selected to power the Gulfstream G550. The BR710 comprises a diameter single-stage fan, driven by a two-stage LP turbine, supercharging a ten-stage HP compressor (scaled from the V2500 unit) and driven by a two-stage, air-cooled, HP turbine. This engine has a thrust-specific fuel consumption (TSFC) of at static sea level takeoff and at a cruise speed of Mach 0.8 ...
