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.
28.49kN variant used on the Dassault Falcon 7X Originally 6,100lb-thrust (27.1kN) growth version of the PW306, smaller than the PW308, featuring swept-blade fan, increased core airflow, low NOx emissions combustor, increased turbine capacity and a more efficient exhaust mixer; integrated propulsion system including Macchi/Hurel Dubois nacelle and thrust-reverser ; certification scheduled for the end of 2004.
