Pratt & Whitney PW2000

The aircraft engines of the Pratt & Whitney PW2000 series are turbofan engines with a high bypass ratio of the medium thrust class from Pratt & Whitney . The engine was designed for the Boeing 757 , in which it competed with the Rolls-Royce RB211-535 until this aircraft series was discontinued .

In 1994 an improved version with higher reliability, lower maintenance costs and better environmental friendliness was presented.

The current version is the PW2043 with 191 kN (43,000 lbf ) takeoff thrust and higher thrust at high altitudes or at high temperatures. Older engines can be upgraded to the PW2043 in accordance with various service bulletins.

In addition to the 757, the PW2000 can be found in the Ilyushin Il-96M under the type designation PW2337 and under the military designation F117-PW-100 in the military transporter Boeing C-17 Globemaster III.
