The engine has two contra-rotating rotors (fans) on the outside of the engine nacelle, either at the front of the assembly ("tractor") or at the rear ("pusher"). Both pusher and tractor open rotor designs form part of Rolls-Royce's long-term "15-50" vision, which is examining various architectures to tackle the 150 seat-aircraft market.
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 Honeywell HTF7000 is a turbofan engine produced by Honeywell Aerospace.Rated in the 6,540–7,624 lbf (29.09–33.91 kN) range, the HTF7000 is used on the Bombardier Challenger 300/350, Gulfstream G280, Embraer Legacy 500/450 and the Cessna Citation Longitude.
The GE Passport is a high bypass ratio turbofan. The engine is a twin-spool, axial-flow turbofan with a high bypass ratio of 5.6:1 and an overall pressure ratio of 45:1. The front fan is attached to the three-stage low-pressure compressor; the 23:1 pressure ratio 10-stage high-pressure compressor includes five blisk stages for weight reduction.
After the Advanced Technology Fan Integrator demonstrator first ran on March 17, 2001, which became the PW1000G, Pratt & Whitney Canada was searching for a launch customer for the initially geared PW800, in the 10,000–19,000 lbf (44–85 kN) thrust range, bridging the gap between P&WC's PW300 and P&W's PW6000, intended for the regional- and ...
The FJ44-1A has a single stage blisk fan plus a single intermediate pressure (IP) booster stage, both driven by a 2 stage low pressure (LP) turbine, and supercharging a single stage centrifugal high pressure (HP) compressor, driven by a single stage uncooled high pressure (HP) turbine. The combustor is an impingement cooled annular design.
The AE 3007 is a direct drive turbofan engine with a single stage fan, a 14-stage axial compressor with 6 stages of variable vanes including inlet guide vanes, an annular combustor, a two-stage high pressure turbine and a 3-stage low pressure turbine.
It is built around an 0.72 scale of the GE90-110B/115B core [1] and contains a Pratt & Whitney fan and low-pressure system design. The competing Rolls-Royce Trent 900 was named as the lead engine for the then-named A3XX in 1996 and was initially selected by almost all A380 customers. However, the GE/PW engine increased its share of the A380 ...
