Pratt & Whitney’s geared turbofan (GTF) demonstrator engine has been cleared for flight testing after successfully completing its phase II ground tests.
The GTF engine uses a gear system which allows the engine’s fan to operate at a different speed than the low-pressure compressor and turbine. This means that the engine offers greater fuel efficiency, reduced emissions and a slower fan speed, cutting engine noise.
Pratt & Whitney next generation product family VP Bob Saia says: “The ground test programme has been a complete success and the geared turbofan engine has met or exceeded all performance targets.

“This demonstrator engine has confirmed the laboratory results of our fan drive gear system demonstrating excellent efficiency and operational characteristics.”
The GTF has been selected to power for Japan’s Mitsubishi Regional Jet and Bombardier’s CSeries.
