The age of supersonic flights is inching closer to reality with advancements happening quite at the speed of the concept itself. In a boost to supersonic air travel, Boom Supersonic, the aerospace company building the world’s fastest airliner, unveiled its supersonic demonstrator, XB-1 on October 7, 2020. For Boom Supersonic, planning a commercial airliner that can fly supersonic, the first independently developed supersonic aircraft, XB-1 demonstrator prototype will begin flight testing in 2021. This first independently developed supersonic aircraft ushers in new era of supersonic flight and include developing one of the highest-efficiency civil supersonic engine intakes ever tested. With the delta wing that balances low-speed stability at takeoff and landing with high-speed efficiency, the jet is propelled by three J85-15 engines that are designed by General Electric, and provide XB-1 more than 12,000 pounds of thrust, allowing it to fly at breakthrough supersonic speeds.
