Boom Supersonic Mach 2.2 airliner combines Honeywell avionics, GE engines, carbon fiber, 3D-printed components

PARIS AIR SHOW. ​Boom Supersonic in Centennial, Colorado, is introducing what promises to be the fastest civil air transport vehicle, capable of reaching 1,451 miles per hour (mph) – just shy of Mach 2.2 but still faster than the Concorde at 1,354 mph. Company officials unveiled the completed design of the XB-1 Supersonic Demonstrator, a subscale prototype of the Boom supersonic passenger airliner, slated to fly next year, when it is expected to solidify its place in the history books as the world’s fastest civil aircraft.

PARIS AIR SHOW. ​Boom Supersonic in Centennial, Colorado, is introducing what promises to be the fastest civil air transport vehicle, capable of reaching 1,451 miles per hour (mph) – just shy of Mach 2.2 but still faster than the Concorde at 1,354 mph. Company officials unveiled the completed design of the XB-1 Supersonic Demonstrator, a subscale prototype of the Boom supersonic passenger airliner, slated to fly next year, when it is expected to solidify its place in the history books as the world’s fastest civil aircraft.

The XB-1 Demonstrator will fly with General Electric engines, Honeywell avionics, Tencate carbon-fiber prepreg, and 3D-printed components from Stratasys. Final assembly and vehicle integration are taking place in Boom’s facility at Centennial Airport, near Denver, Colorado.

“We now have everything required to build history’s first independently developed supersonic aircraft — the funding, technical design, and manufacturing partners,” Boom Supersonic Founder and CEO Blake Scholl explains.

The XB-1 design has been refined and optimized since it was unveiled last fall. The completed design has passed a major external design review, verifying that it meets performance and safety standards ahead of component manufacturing and assembly. Among the major changes, the XB-1 now has a third inlet located in the tail to provide greater propulsion system stability, and to improve aircraft performance and safety. In addition, the XB-1 wing design has evolved with the vertical tail modified to improve performance in crosswind conditions.

Boom’s current order book for the supersonic airliner now totals 76 aircraft across five world airlines. The new aircraft reservations are backed by tens of millions in non-refundable payments.

“Airlines are excited for something new and different to offer their passengers — and we’re thrilled that major world airlines share our vision for a future of faster, more accessible supersonic travel. We look forward to sharing more about these partnerships in the future,” Scholl adds.

The XB-1 Demonstrator will take its maiden flight in 2018. Subsonic flight testing will be conducted near Denver; supersonic test flights will take place near Edwards Air Force Base in Southern California.
