Pratt & Whitney Canada is showcasing its latest green engine technologies at Paris centered on the 10,000-pound-thrust-class PW-10X engine it is developing for business jets and regional airliners.

The company said the engine will “raise the bar on performance, economics and environmental responsiveness,” beating current ICAO emissions standards by more than 35 percent for carbon monoxide and more than 50 percent for nitrous oxide, unburned hydrocarbons and smoke emissions. A “step change” in fuel burn is also promised, while noise will be reduced to “well below Stage 4 standards.”

P&WC is investing $1.5 billion Canadian over the next five years to build on its green engine expertise. “We have a rigorous plan in place to achieve this,” said executive vice president John Sabbas.

P&WC is one of five engine manufacturers developing “super-green” engines in the 10,000-pound-thrust class, although at Paris few details of their respective offerings were being revealed. Rolls-Royce, winner of the competition to power the Dassault super-midsize business jet, remained tight-lipped about the RB282-31, while GE barely admits it is even considering an all-new follow-on to its highly successful CF-34 range. Snecma’s Silvercrest is already announced but has yet to find a customer, and Honeywell is pushing ahead with development of its HTF10000, which builds on the 7,000-pound-thrust HTF7000.
