Boom Supersonic, the company building the world’s fastest airliner, has unveiled Symphony, a new propulsion system designed and optimised for its Overture supersonic airliner. Boom also has 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.
“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. “Through the Symphony programme, 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.”
Symphony will be a bespoke design leveraging proven technologies and materials to achieve optimal supersonic performance and efficiency. Overture’s new propulsion system will operate at net-zero carbon and meet Chapter 14 noise levels. 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%.
With Symphony design already underway, Overture is on track to achieve type certification in 2029. Production is set to commence in 2024 at Overture’s Superfactory in Greensboro, NC, with rollout in 2026 and first flight in 2027.
