|
Pratt & Whitney's PW2000 series engines is a high-bypass turbofan aero engine with a thrust range from 37,000 to 43,000 lbf (165 to 190 kN) built by Pratt & Whitney . It is designed for the Boeing 757. As a 757 powerplant, the engine competes with the Rolls-Royce RB211-535. An improved version launched in 1994, offers better reliability, durability and reduced total maintenance cost, along with excellent environmental performance.
The current build standard is the PW2043, providing 43,000 lbf (190 kN) thrust. The PW2043 provides good fuel efficiency and additional thrust capability at high altitudes and/or elevated temperatures. Current engines can be converted to a PW2043 through minor modification.
Besides the 757, the PW2000 series engines also power the Ilyushin Il-96M and the C-17 Globemaster III military transport, where in its military guise, designated as the F117-PW-100.
