Pratt & Whitney Canada PW500
From Wikipedia, the free encyclopedia
The Pratt & Whitney Canada PW500 is a series of medium thrust turbofan engines designed specifically for business jet applications.
The PW530 family 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 family 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.
[edit] Applications
The PW530 powers the Cessna Citation Bravo business jet. Two PW535's propel the Cessna Citation Ultra Encore, whereas twin PW545's power the Cessna Citation Excel bizjet.
