The Boom Overture is a proposed Mach 1.7, 65–88 passenger supersonic airliner with 4,250 nmi of range, which is planned to be introduced in 2029 by Boom Technology.The aircraft is planned to have a delta wing configuration (similar to the Concorde), but will be built with composite materials.
A 25% improvement in time on wing, reducing total airline operating costs by 10% when compared to derivative engine approaches.Overture’s wing configuration is a conventional compound delta for low supersonic drag, designed to be like a 75% scale model of Concorde.
It features no low sonic boom unlike the SAI Quiet Supersonic Transport (QSST), or laminar supersonic flow technology from the Aerion AS2.Due to the low 1.5 wing aspect ratio, low-speed drag is high, and the aircraft requires high thrust at take-off.
Boom also needs to address the nose-up attitude on landing.Airframe maintenance costs are expected to be similar to those of other carbon fiber airliners.
Design changes announced in July 2022 included an increase in the number of engines to four to allow for smaller less technically challenging engines and to allow takeoff at derated levels to lower noise, and redesigned gull form wing and fuselage to reduce drag.
The Boom Symphony is a two-spool medium-bypass turbofan engine under development for use on Overture. The Symphony engine design, which is already underway, is to be compliant with FAA and EASA Part 33 requirements, according to the manufacturer.
The engine is designed to produce 35,000 pounds (160 kN) of thrust at takeoff and sustain Overture supercruise at Mach 1.7, and burn sustainable aviation fuel exclusively.
With a range of 4,250 nautical miles. Optimized for speed, safety and sustainability, Overture is also being designed to fly more than 600 routes around the world in as little as half the time. Flying from Miami to London in just under five hours./wikipedia
