Boom Supersonic has determine a new focal ratio disk for its XB-1 epitome aircraft while confirming the stability of its design at eminent speeds for subsonic flight . The successful test puts us one step nigher to catch the reappearance of commercial ultrasonic flight — 21 class after Concorde strike out .
On Nov. 5 , the XB-1 attain 629 mph ( 1,012 km / hr ) for the first time — tantamount to Mach 0.82 , where Mach 1.0 is thespeed of sound . Marking its seventh test flight , this 55 - minute missionary work also reached a new flight of stairs roof of 23,015 invertebrate foot ( 7,015 meters ) and confirm the prophylactic of its cockpit pressurization systems .
Eleven Clarence Shepard Day Jr. later , the XB-1 completed its 8th trial flight , a 54 - hour run in which it carried out nourish Mach 0.8 operation without the assistance of its constancy augmentation organization .
This automated system typically helps keep the XB-1 stable during flights , standardised to thefly - by - wireelectronic stabilisation system of rules used in New belligerent aircraft . Boom Supersonic wanted to demonstrate that the XB-1 is not entirely dependent on its stableness augmentation system to stay in the air and can be manually operated at high speed safely , the firm express .
The aircraft has been in development for eight years and completed its first mental testing trajectory in l March 2024 – which lasted just 12 minutes .
Other recent milestone include successful " flutter " tests at mellow speeding , which prove the structure of the aircraft is not susceptible to destructive vibrations get by airflow at high fastness , and thefirst successful in - flight of steps use of its landing gear .
Boom Supersonic aims to complete 10 subsonic flight of stairs before fight before with supersonic tests by the kickoff of 2025 .

" XB-1 continues to do at more and more faster speeds and high-pitched altitudes , blow up the flight of stairs envelope gradually to prepare the aircraft and team for breaking the healthy barrier at Mach 1 , " Boom Supersonic representatives said in astatement .
The XB-1 is a demonstrator craft , intended to make a fount for the company ’s technology to one day be used in commercial-grade military operation . These run flights are accent - testing Boom Supersonic ’s in - business firm carbon fiber composite blends for airframe , as well as its custom engine intakes , which facilitate traditional fanjet engines speed up to supersonic upper more expeditiously .
The XB-1 tests will give now into the cosmos of the Boom Overture , a proposedsupersonic passenger aircraftcapable of traveling as fast as Mach 1.7 — or 1,304 mph ( 2,099 km / h ) . This is nearlyas fast as the Concordeand would enable rider to travel from London to New York or Newark in approximately 3 60 minutes and 30 minutes .
