Rolls-Royce has decided to withdraw from the current competition to power Boeing’s proposed middle of the market – or New Midsize Airplane (NMA) – platform. The company says they believe the platform complements Boeing’s existing product range, but they are unable to commit to the proposed timetable.
“This is the right decision for Rolls-Royce and the best approach for Boeing,” Chris Cholerton, Rolls-Royce, president – Civil Aerospace, says. “Delivering on our promises to customers is vital to us and we do not want to promise to support Boeing’s new platform if we do not have every confidence that we can deliver to their schedule.”
The company says it is focused on their commitment to customers to deliver on current engine programs, but say they remain committed to the development of new technologies. A company release said they will continue to mature and de-risk their next generation UltraFan engine architecture in preparation for future applications.
Chris Cholerton added: “UltraFan is the foundation of our future large civil aero engine programs and we must ensure that it has as smooth an entry into service as possible. We had begun its development before the Boeing opportunity emerged and it must undergo a rigorous testing regime before we offer it to customers, which we do not believe can be achieved within the NMA timeframe. Withdrawing at this stage will enable Boeing to structure the final part of the competition in a way that best suits them and we hope and expect to work with Boeing on other new opportunities in the future.”
Rolls-Royce says their UltraFan, shown here, is a scalable jet engine design suitable for widebody or narrowbody aircraft and will offer a 25 percent fuel efficiency improvement over the first-generation of Rolls-Royce Trent engines. They have successfully run tests of the new architecture that sits within the core of the engine through the Advance3 demonstrator, as well as the power gearbox and composite fan blade system. The announcement added that meeting Boeing’s timetable “would have required accelerating our demonstrator program and withdrawing from the process will enable us to have a high confidence in engine maturity towards the end of the next decade.”
