Pratt & Whitney believes open rotors are not the solution to powering future single-aisle aircraft and will offer developed versions of its PW1000G series of geared turbofans for all new and derivative single-aisle aircraft.

“We believe we can get better fuel efficiency than open rotors with our engine by leveraging the technology we already have,” said Bob Saia, vice president, P&W next-generation product family. He added that in its most developed form the geared fan engine could bring 30- to 35-percent reduction in fuel burn over today’s engines. “That’s better than an open rotor and it has none of the noise and installation negatives.
