Update, April 10: Aircraft Technology’s April issue is now published with a feature on Boeing’s prospective new airplane. There is a sidebar transcript with Boeing’s Mike Bair, who talks about the GTF and the competing engines. The report is here; the story begins on PDF page 58.
Scott Hamilton’s second part of his discussion with Pratt & Whitney’s Bob Saia. They discuss the new engines coming out as well as new airplane programs. We have an interesting view of open rotors – an open rotor needs more than double the diameter of a regular fan engine.
Interestingly, Airbus will be getting a more advanced version of the GTF to enable the increased thrust required. But they will maintain fuel efficiency at the same levels though. Looking ahead, a new Boeing in circa 2020 could see new blades, and other aerodynamics and lighter materials as an engine option.
