Pratt & Whitney Canada is striving to keep fuel burn on target for its PW307A engine, which will power the Dassault Falcon 7X. Based on results from the first series of engine flight tests, the Longueuil, Quebec-based manufacturer is confident it will avoid the fuel-consumption problem it had on the PW308C for the Falcon 2000EX. P&WC anticipates Transport Canada will certify the PW307A, which has a takeoff thrust of 6,100 pounds (uninstalled, ISA+18.4), late this year.
Compared with the PW308C, which yielded disappointing specific fuel consumption, the development of the PW307A has been “much more rigorous,” Mike Perodeau, P&WC’s vice president for corporate aviation, and Catrina MacKenzie, vice president for the PW307 program, told AIN. The engineers endeavored to get data from every component of the engine, as they wanted to have a clear understanding in modeling performance. “We have done a lot of performance validation through computational fluid dynamics and rig and component testing,” MacKenzie said.
