Dassault Falcon 7X
Fairchild Dornier 328JET
Design and developmentEdit
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.
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.
