Sylvain Faust, who follows the Bombardier CSeries more closely than anyone else we know except the program participants, last night posted a piece that says the Pratt & Whitney Geared Turbo Fan engine now in testing with the CSeries is up to 25,000 lbs of thrust–a 9.3% increase. The thrust bump is more geared toward take-off performance than economy, Faust reports. The CS100 is a short-field, hot-and-high airplane, among its other attributes.
Pratt & Whitney declined to comment directly on Faust’s report.
“Pratt & Whitney is on track to meet the PW1500G engine commitments made to customers on entry into service. Our focus remains on successfully supporting Bombardier in the completion of aircraft certification testing and meeting all of our performance commitments on schedule,” a spokeswoman said.
Meanwhile, Bombardier posted a short video update on the program.
