The PW 300 series has been developed in partnership with MTU who are responsible for the low pressure turbine. The first variant, the PW305A, has the following configuration and was designed with a core flexible enough for engines with take-off thrusts from 20 kN to 31 kN (4,500 to 7,000 lb): a single-stage fan driven by a three-stage low pressure turbine, supercharging a four-stage axial ...
Rolls-Royce Tay on a Fokker 100, with thrust reverser engaged. Originally designated 610-8, all but one training engine have now been converted to 611-8 standard. The newest variant is the 611-8C, which has cast HP1 turbine blades, larger fan from the 650-15, structural by-pass duct and FADEC .
The family of engines generates 15,000 to 34,000 lbf (67 to 151 kN) of thrust, it uses gearboxes rated between 16,000 hp (12,000 kW) and 32,000 hp (24,000 kW). [39] By putting a 3:1 gearbox between the fan and the low-pressure spool, each spins at its optimal speed: 4,000–5,000 RPM for the fan and 12,000–15,000 RPM for the spool, the high ...
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 37,000 to 43,000 lbf (160 to 190 kN). Built by Pratt & Whitney, they were designed for the Boeing 757.
Turbine: 3 stage: single stage high pressure, three stage intermediate pressure and two stage low pressure Performance Maximum thrust : 5,440 lbf (24.20 kN) take off, 1,055 lbf (4.69 kN) cruise
The engine was first run in August 1967 before being test flown on an Avro Canada CF-100 Canuck in an underslung external test pod. [3] In 1975 a unique over-wing installation in place of Pratt & Whitney Canada PT6 turboprops was fitted to a Beechcraft Super King Air and flown for 93 hours to investigate the use of turbofan engines on that ...
The ATF's increasing weight during development required more thrust to meet the performance requirements; as gross weight grew to 60,000 lb (27,200 kg), the required maximum thrust was increased by 20% to 35,000 lbf (156 kN) class. Pratt & Whitney's design changed to incorporate a 15% larger fan, increasing bypass ratio from 0.25 to 0.30.
[3] 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 ...
