The Pratt & Whitney Canada PW500 is a series of medium thrust turbofan engines designed specifically for business jet applications.

Design and development[edit]

The PW530 has a single stage fan, driven by a 2 stage LP turbine, supercharging a 2A/1CF axial-centrifugal HP compressor, driven by a single stage HP turbine.

Although similar in configuration, the PW535 has a T-stage, mounted on the LP shaft behind the fan, to increase overall pressure ratio and core flow.

Similar to the PW535, the PW545 has an additional LP turbine stage to drive a larger diameter fan.
