PW500

MTU has been cooperating with Pratt & Whitney Canada since 1993 on the PW500 engine family for medium-size business jets. MTU has a stake of 25 percent in this program.

Engines of the PW500 family are two-shaft turbofans. MTU’s contribution includes the development and manufacture of the complete low-pressure turbine including the exit casing and the mixer for the PW530 and PW545 models.
