In November 2024, Boom Supersonic announced that the XB-1 had completed the eighth out of ten planned subsonic flights. [15] The XB-1 is considered a precursor to Boom's first supersonic commercial airliner. [5] The 64-80 seat aircraft, Overture, will be the first supersonic passenger jet since the British-French Concorde which was retired in 2003.
The Lockheed Martin X-59 Quesst ("Quiet SuperSonic Technology"), sometimes styled QueSST, is an American experimental supersonic aircraft under development by Skunk Works for NASA's Low-Boom Flight Demonstrator project. [2] Preliminary design started in February 2016, with the X-59 planned to begin flight testing in 2021.
The XB-1 "Baby Boom" is 68 feet (21 m) long with a 17 ft (5.2 m) wingspan and a 13,500-pound (6,100 kg) maximum take-off weight. Powered by three General Electric J85 engines with variable geometry inlets and exhaust, the prototype should be able to sustain Mach 2.2 with more than 1,000 nmi (1,900 km; 1,200 mi) of range. [ 6 ]
The Boom Overture is a supersonic airliner under development by Boom Technology, designed to cruise at Mach 1.7 or 975 knots (1,806 km/h; 1,122 mph). It will accommodate 64 to 80 passengers, depending on the configuration, and have a range of 4,250 nautical miles (7,870 km; 4,890 mi). Boom Technology aims to introduce the Overture in 2029. [2]
The Boom XB-1 Baby Boom third-scale testbed, first test flown on on March 22, 2024, the aircraft is powered by three General Electric J-85-15 turbojets. [57] On January 28, 2025, the aircraft reached speeds of Mach 1.122, making it the first human-piloted civil supersonic flight in an aircraft using an air-breathing engine since Concorde’s ...
The Boom Symphony is a medium-bypass turbofan engine under development by Boom Technology for use on its Overture supersonic airliner. The engine is designed to produce 35,000 pounds (160 kN) of thrust at takeoff, sustain Overture supercruise at Mach 1.7, and burn sustainable aviation fuel exclusively.
STAC stated that an SST would have economic performance similar to existing subsonic types. [8] Lift is not generated the same way at supersonic and subsonic speeds, with the lift-to-drag ratio for supersonic designs being about half that of subsonic designs. [16] The aircraft would need more thrust than a subsonic design of the same size.
Aerial view of Oklahoma City (1974 photograph) A Convair B-58 Hustler, one of the airplane models used in the Oklahoma City sonic boom tests The Oklahoma City sonic boom tests, also known as Operation Bongo II, refer to a controversial experiment, organized by the Federal Aviation Administration (FAA), in which 1,253 sonic booms were generated over Oklahoma City, Oklahoma, over a period of six ...
