  • Bizjet engine battles - Pratt Canada scores another one
    Posted by Graham Warwick 5:13 PM on May 12, 2008

    Bombardier has chosen Pratt & Whitney Canada's PW307B turbofan to power its new all-composite Learjet 85. This is a derivative of the PW307A powering Dassault Falcon 7X and a cousin to the PW305A that powers the Learjet 60.

    That makes it P&WC 2, Honeywell 2 and Rolls-Royce 2 in the competition to power the spate of newly launched business jets, with more announcements still to come. Honeywell will power Embraer's MLJ and MSJ with the HTF7000E; R-R the Dassault Future Falcon (with the RB282) and Gulfstream G650 (with the BR715); and now Pratt Canada has added the Learjet 85 to the recent selection of its all-new PW810 to power Cessna's Citation Columbus. Still to score are GE with the CF34 and Snecma with its all-new Silvercrest.

    Producing 6,400lb takeoff thrust on the trijet Falcon 7X, the PW307 will be rated at 6,100lb in the twin-turbofan Learjet 85. But thrust is not the discriminator - in a sure sign of things to come, P&WC says the engine "offers the least environmental impact of any engine in its class," including the ability to land at green-minded Zurich airport without incurring emissions surcharges.
