Epstein Talks (Geared Turbofan) Technology with Airplane Geeks

Alan Epstein, vice president, Technology & Environment, Pratt & Whitney, is featured on episode No. 182 of the Airplane Geeks podcast. In a 32-minute interview with Max Flight and friends, Epstein fields questions about the history and evolution of the geared turbofan technology, the benefits of the Pratt & Whitney PurePower engine, and the engine's impact on the marketplace.

" ... The history for the last 20, 30 years has been the airframers have said we're going to build this airplane, give us a proposal for an engine. The GTF is unique. ... There was this demo engine that flew in 2007, and the communications people painted a slogan on the nacelle that said 'This Changes Everything.' And I thought that was advertising enthusiasm, but to my surprise, it has. The fact that the GTF is there made the Bombardier and MRJ airplanes so attractive, forced Airbus and Boeing to do something - they could've come up with new airplanes or re-engine. They chose to re-engine. So this is getting back to the good old days from an engine point of view, where you build a great engine and people start designing airplanes around it. ..."
