The PW 300 series has been developed in partnership with MTU who are responsible for the low pressure turbine.
The first variant, the PW305A, has the following configuration and was designed with a core flexible enough for engines with take-off thrusts from 20 kN to 31 kN (4,500 to 7,000 lb): a 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 used. There is no forced mixing before the bypass and core streams leave the engine through a common nozzle. The engine is controlled with a dual channel Full Authority Digital Engine Control (FADEC) system.[2]
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.[3]
Unscheduled interventions went from 85% in 2015 to 20% in 2017, driving up the PW307 availability thanks to Pratt's digital platform, and engine dispatch reliability is at 99.4% for the Falcon 7X/8X powered by the PW307.[4]
