Boom Supersonic has announced the appearance of the new Symphony engine for its Overture supersonic aircraft. About informs company press office.
The first supersonic airliner appeared in the second half of the 20th century, but without success. They were distinguished by excessive noise, high fuel consumption and complexity of design, which increased the cost. In recent years, evidence has emerged that it is possible to get rid of all three of these problems.
The new Symphony engine should solve all three problems in many ways. It does not need an afterburner to get the required thrust, consumes less fuel than Concorde engines, and its design has been optimized and simplified. For this reason, the developers estimate that the average time spent in flight [а не в ремонте] It will increase by 25% and the maintenance cost will decrease by 10%. The creation was carried out in partnership with Florida Turbine Technologies, where many former engine developers for the F-22 and F-35 fighters worked.

The Symphony will be a mid-bypass turbofan engine. In terms of basic architecture, it is similar to other typical airliner engines. The differences relate to operation in supersonic mode, so the design includes an axisymmetric supersonic air intake developed by Boom and a low-noise variable geometry nozzle, as well as a passively cooled high-pressure turbine. At takeoff, each engine will produce 35,000 pound-force (15,800 kilogram-force) of thrust.
The overture will be certified in 2029. Production will begin in 2024 and the first flight tests will take place in 2027. Preliminary agreements for the supply of these aircraft have already been signed with United Airlines.
