The Pratt & Whitney PW1000G family, also marketed as the Pratt & Whitney GTF (geared turbofan), is a family of high-bypass geared turbofan engines produced by Pratt & Whitney. Following years of development and testing on various demonstrators, the program officially launched in 2008 with the PW1200G destined for the Mitsubishi SpaceJet (a ...
The -5 model was certified in 1982, and a decade later, an engine utilizing the TFE731-5 power section and a TFE731-3 fan was built and designated the TFE731-4, intended to power the Cessna Citation VII aircraft. [4] The most recent version is the TFE731-50, based on the -60 used on the Falcon 900DX, which underwent its flight test program in ...
The geared turbofan is a type of turbofan aircraft engine with a planetary gearbox between the low pressure compressor / turbine and the fan, enabling each to spin at its optimum speed. The benefit of the design is lower fuel consumption and much quieter operation.
A 1976 study included an evaluation of the armor required to contain the energy from 1 blade, 2 blade, and 4 blade fragments of the compressor and turbine stages of General Electric CF6 and Pratt & Whitney JT9D engines; although the 4 blade fragment was unlikely to occur, containing it would have required a steel plate 1.212 inches (30.8 mm ...
In total, 28 test engines will be used by CFM to achieve engine certification, and 32 others will be used by Airbus, Boeing and COMAC for aircraft certification and test programs. [1] [17] The first engine entering the test program reached and sustained 33,000 lbf (150 kN) of thrust, required to satisfy the highest rating for the Airbus A321neo ...
The U.S. government's auto safety regulator has ended a 2 1/2-year investigation into Ford engine failures after the company replaced engines or extended the warranty on some vehicles.
The recall includes all codes between 2305140 to 2405170 for the cakes, 3174 to 4047 for the cones and 2307187 to2406163 for the sandwiches with plant code 24-65, 24-0065, 2465, 240065.
The Honeywell FX5 was a 6,000lb-thrust (27kN) geared turbofan based on a technology demonstrator core. Aiming for a 20%-plus reduction in the cost of ownership from the TFE731-60 and to span a 3,000–8,000 lbf (13–36 kN) family, it could have been certificated within 36 months. [1]
