Boom, the U.S. start-up working on ambitious plans to bring a supersonic airliner into commercial service by the end of this decade, says it will develop its own engine for the Overture program with a team of engine designers, an additive manufacturer, and a turbine engine maintenance specialist. On December 13, the company announced a trio of partners for the planned Symphony turbofan, including Florida Turbine Technologies, a unit of Kratos Defense & Security Solutions, which will design the engine; GE Additive providing additive technology design consulting; and StandardAero for engine maintenance.

The new engine will produce 35,000 pounds of takeoff thrust and features a twin-spool architecture with a single-stage fan and a passively cooled high-pressure turbine using traditional hot-section materials. The medium-bypass-ratio engine will not be equipped with an afterburner.
