Īt the June 2019 Paris Air Show, Blake Scholl announced the date for first flight was pushed out to 2020, six months later than previously planned after including a stability augmentation system for better safety at high speed and at take-off and landing. With total investment rising to $200 million, Boom was funded for XB-1 flight-testing to the end of 2020. The carbon-fiber layup of the fuselage halves was to begin in early 2019 for final assembly of the forward fuselage at the beginning of Spring.
These tests had taken a decade on Concorde. Tunnel testing finished in November 2018, including takeoff and landing with gear doors' impact on stability as well as supersonic inlet testing. The second set of tests confirmed accurate calibration, and a third set of tests confirmed design safety. The first indicated that predicted calibration was off by 30%.
The XB-1 design went through three sets of wind-tunnel tests. Flight tests were delayed again for 2019 due to challenging aerodynamics and further engine change from the 3,500 pounds-force (16,000 N) J85-21 to the 4,300 lbf (19 kN) J85-15. The Spaceship Co., manufacturer of Virgin Galactic’s vehicles, was announced as a partner for flight tests in Mojave, California. īy July 2018, the aerodynamic design was completed, the horizontal tail assembled, and the engines received. First expected supersonic flight slipped to 2019. In 2017, the composite wing spar was load tested while being heated in a hydraulic testbed at 300 ☏ (149 ☌), above the heat soak operational temperature. It was then anticipated that flight tests would start late 2018. Its preliminary design review was completed by June 2017, with a switch of engine to the military version of the J85 to take advantage of its extra thrust. īy April 2017, enough financing was secured to build and fly it. The design was unveiled in Denver on November 15, 2016, and it was initially intended to make its first subsonic flight in late 2017, powered by three General Electric CJ610 turbojets (a civilian J85), with subsequent supersonic flight testing at Edwards Air Force Base. Powered by three General Electric J85s, it is planned to maintain Mach 2.2, with over 1,000 nautical miles (1,900 km 1,200 mi) of range. The Boom XB-1 "Baby Boom" is a one-third-scale trijet supersonic demonstrator designed by Boom Technology ( dba "Boom Supersonic" ) as part of development of the Boom Overture supersonic transport airliner.
