The Pratt & Whitney PW2000, also known by the military designation F117, is a series of high-bypass turbofan aero engines with a thrust range from 37,000 to 43,000Â lbf (165 to 190Â kN). Built by Pratt & Whitney, they were designed for the Boeing 757. As a 757 powerplant, these engines compete with the Rolls-Royce RB211.
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 and grew into the PW2000.
The PW2000 is a dual-spool, axial air flow, annular combustion, high by-pass 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 developed the low-pressure turbine and turbine exit casing as well as producing critical parts of the low-pressure turbine, the turbine exhaust casing, high-pressure compressor and high-pressure turbine components.
