The Pratt & Whitney Canada PW300 series is a family of turbofan engines developed by Pratt & Whitney Canada specifically for business jet applications.
The basic configuration of the PW300 is as follows: single stage fan, driven by a three-stage low pressure turbine, supercharging a four-stage axial/single stage centrifugal high pressure compressor, driven by a two stage high pressure turbine. An annular combustor is featured. Some versions have an unmixed exhaust, but the PW306 and PW308 include a forced mixer. A Full Authority Digital Engine Control (FADEC) system is incorporated.
The PW307A is a new centre-line engine developed specifically for a tri-jet application on the Dassault Falcon 7X. The PW307 was certified by Transport Canada in March 2005.
The PW308A has been chosen to power the Scaled Composites White Knight Two, the launch aircraft for Virgin Galactic's SpaceShipTwo.
