The engine has an overall pressure ratio of 35:1, which is extremely high for an engine with a centrifugal compressor. Other cycle parameters are a bypass ratio of 5.3 and airflow of 240 lb/s (108.9 kg/s).
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 Garrett TFE731 (now Honeywell TFE731) is a family of geared turbofan engines commonly used on business jet aircraft. Garrett AiResearch originally designed and built the engine, which due to mergers was later produced by AlliedSignal and now Honeywell Aerospace.
The development of the PW800 stretches back to demonstration projects in 1999, soon after the development of the PW600 very light engine and the PW300 business jet engine. [1] 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 ...
The engine's design is unusual; the core flow path is reversed twice. Aft of the fan, the axial compressor has five stages, after which the gas path progresses to the aft end of the engine. There, it is reversed to flow through a centrifugal compressor stage, the combustors and then the turbine stages.
The Williams F107 (company designation WR19) is a small turbofan engine made by Williams International.The F107 was designed to propel cruise missiles.It has been used as the powerplant for the AGM-86 ALCM, and BGM-109 Tomahawk, as well as the experimental Kaman KSA-100 SAVER and Williams X-Jet flying platform.
The engine has a wide-chord swept fan, two-stage low-pressure compressor and counter rotating high-pressure compressor based on a titanium impeller, for a 2,050 lbf (9.1 kN) takeoff thrust. [5] The HF120 engine's components interact with greater efficiency by incorporating 3D aerodynamic design, and its effusion-cooled combustor design emits ...
The engine was given a United States military aircraft engine designation of YF102-LD-100. [1]: 190 Six YF102 engines were built for the YA-9. The 7,500 lbf (33 kN) thrust engines powered the A-9A prototypes for seven months of flight tests in 1972, recording 238 flights and 652 flight hours. [3]
