The Supersonic Prototype XB-1 Completes Its Fourth Flight and Exceeds Mach 0.6
Boom Supersonic has announced the continued progress of its supersonic aircraft prototype XB-1, which is getting closer to reaching Mach 1. Since its historic first flight on March 22, 2024, the aircraft has been conducting a series of flight tests to evaluate its performance and maneuverability, with approximately 10 subsonic flights planned before transitioning to supersonic speeds.
The XB-1 serves as the foundation for the development of Overture, Boom's supersonic airliner. This prototype incorporates advanced technologies, including aerodynamics optimized through numerical modeling, carbon fiber materials, advanced air intakes for supersonic engines, and an augmented reality vision system to enhance visibility during takeoff and landing phases.
During its latest flight, the XB-1 reached an altitude of 16,150 feet and a speed of Mach 0.617 (313 KIAS), with a flight duration of approximately 48 minutes. This test also validated several key points, including in-flight use of the Flight Excitation System (FES), handling checks between 225 and 300 knots, application of high g-forces (up to 2.78 g) in preparation for supersonic flight, and landing gear maneuvers at 225 knots.
Boom Supersonic has already recorded 130 orders and pre-orders for its Overture project, including from American Airlines, United Airlines, and Japan Airlines. Overture is designed to carry 64 to 80 passengers at twice the speed of current subsonic aircraft while being optimized for safety, sustainability, and capable of operating on sustainable aviation fuel (SAF).
Production of Overture is expected to begin by the end of 2024 at the super-factory in Greensboro, North Carolina.
