Rolls Royce Exits Boom's Supersonic Airliner Project

Rolls-Royce has ended its involvement in a project by Boom Supersonic to develop a faster-than-sound passenger airliner, leaving unclear the powerplant options available to Boom. FlightGlobal reports: "We are appreciative of Rolls-Royce's work over the last few years, but it became clear that Rolls' proposed engine design and legacy business model is not the best option for Overture's future airline operators or passengers," Boom said on 7 September. "Later this year, we will announce our selected engine partner and our transformational approach for reliable, cost-effective and sustainable supersonic flight." Earlier in the day, news broke that R-R had backed out of the Boom project. "We've completed our contract with Boom and delivered various engineering studies for their Overture supersonic program," the UK engine manufacturer says. "After careful consideration, Rolls-Royce has determined that the commercial aviation supersonic market is not currently a priority for us and, therefore, will not pursue further work on the program at this time. It has been a pleasure to work with the Boom team and we wish them every success in the future." Boom, with offices in Denver, has been developing a supersonic aircraft called Overture that it says will carry up to 80 passengers and cruise at Mach 1.7. It initially intended for Overture to have two engines, but recently changed to a four-engined design. The company has been targeting first flight of Overture in 2026 and first delivery in 2029. "Overture remains on track to carry passengers in 2029, and we are looking forward to making our engine announcement later this year," Boom says.
