Pratt & Whitney Next-Generation Geared Turbofan

Pratt & Whitney recently completed over 175 hours of ground testing of a next-generation Geared Turbofan (GTF) engine propulsor technology as part of the Federal Aviation Administration’s (FAA) Continuous Lower Energy, Emissions and Noise (CLEEN) programme, an FAA NextGen initiative to accelerate the development of environmentally-friendly aircraft technologies. This advancement builds on the completion of 275 hours of fan rig testing of the technology in 2014 and 2015. The demonstrator used an existing development engine from a certified Geared TurboFan product to validate the performance capability of a second-generation, ultra-high bypass fan design.
