MONTREAL—Transport Canada has certified Pratt & Whitney’s geared turbofan engine that will power Bombardier’s new CSeries aircraft.
The US-based engine manufacturer has conducted more than 4,000 hours of testing since September 2010, including 340 hours of flight testing on a Boeing 747 flight test airplane.
The PW1500G engines type certified through Transport Canada were assembled at Pratt & Whitney Canada’s Mirabel Aerospace Centre, north of Montreal.
Each aircraft will be powered by two engines, which use an advanced gear system to allow its fans to operate at a different speed than the low-pressure compressor and turbine.
The 110- to 149-seat CSeries is partially made from advanced composite materials that promise to deliver a 15% reduction in cash operating costs and a 20% fuel burn reduction.
