"The team at Boom understands what we need to create a compelling experience for our passengers, and we are looking forward to a United supersonic fleet powered by Symphony."īoom has selected Florida Turbine Technologies, a business unit of Kratos Defense & Security Solutions, Inc., as its engine design team. "United and Boom share a passion for making the world dramatically more accessible through sustainable supersonic travel," said Mike Leskinen, President, United Airlines Ventures. When compared to derivative approaches, Symphony is expected to deliver a 25% increase in time on wing and significantly lower engine maintenance costs, reducing overall airplane operating costs for airline customers by 10%. Overture's new propulsion system will operate at net zero carbon and meet Chapter 14 noise levels. Symphony will be a bespoke design leveraging proven technologies and materials to achieve optimal supersonic performance and efficiency. "Through the Symphony program, we can provide our customers with an economically and environmentally sustainable supersonic airplane-a combination unattainable with the current constraints of derivative engines and industry norms." "Developing a supersonic engine specifically for Overture offers by far the best value proposition for our customers," said Blake Scholl, Founder and CEO of Boom Supersonic. Boom also announced that it will be teaming with three industry leaders to develop Symphony including Florida Turbine Technologies (FTT) for engine design, GE Additive for additive technology design consulting, and StandardAero for maintenance. 14, 2022 /PRNewswire/ - Boom Supersonic, the company building the world's fastest airliner, today announced Symphony, a new propulsion system designed and optimized for its Overture supersonic airliner. It also noted that "the high cruise altitude of supersonics increases the residence time of emissions significantly.Boom-led collaboration brings together world-class companies across design, manufacturing, and maintenance including FTT, GE Additive, and StandardAero However, the ICAO report said that would be a poor use of scarce SAF fuels, given the high fuel burn compared to a regular jet. In addition, the International Civil Aviation Organization (ICAO) recently bashed supersonic travel, noting in a report that it would use 7-9 times more fuel per passenger, per kilometer, than subsonic jets.īoom has said that it would offset its carbon output through the use of sustainable aviation fuel (SAF). That's the primary direction for the industry right now, given criticism of air travel's contribution to global warming. Pratt & Whitney cited efficiency as an issue for supersonic jets, and other manufacturers said they're focused on reducing fuel-burn. ![]() Honeywell, Safron and GE shut down the idea, while Pratt & Whitney stated that supersonic travel is "tangential" to its business. There are a limited number of other manufacturers capable of developing a supersonic jet engine, and all of the biggest ones said that it's not in their plans. It plans to build build a factory in California and start flying passengers by 2029.Īfter 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. The company has 20 airplanes on order from American Airlines and 15 from United. ![]() "We can reconfirm our intention to announce Boom's selected engine partner and transformational approach for reliable, cost-effective, and sustainable supersonic flight, later this year." Boom told Insider. Now, other major jet engine manufacturers including Pratt & Whitney, GE Aviation, Honeywell and Safran Aircraft Engines have told FlightGlobal they're not currently interested in supersonic aircraft.īoom said that the project is still on track, though, and that it will soon announce an engine partner. After Boom signed an "engagement agreement" with Rolls-Royce for supersonic jet engines back in 2020, the latter announced last week that it had left the project. Boom recently lost its jet engine partner for the Overture supersonic jet, and other major engine manufacturers aren't interested in the project either, Insider has reported.
