Pratt & Whitney Canada PW500

The Pratt & Whitney Canada PW500 is a series of medium-thrust turbofan engines designed specifically for business jets. The PW530 has a single-stage fan driven by a two-stage low-pressure turbine feeding an axial-centrifugal high-pressure compressor driven by a single-stage turbine; the PW535 adds a booster stage and the PW545 adds a further low-pressure turbine stage and a larger fan. The PW530A, rated at 2,887 pounds-force, entered service on the Cessna Citation II Bravo in February 1997, and the PW545 followed on the Citation Excel in July 1998. The PW535 later powered the Citation V Encore and the Embraer Phenom 300. By 2023 about 4,600 PW500 engines had been built and had flown 22 million hours.
