NASA's Sustainable Flight Demonstrator (SFD) project recently concluded wind tunnel tests of its X-66 semi-span model in ...

The countdown has begun for the XB-1’s “historic” first supersonic test flight that should break the sound barrier, according ...

Boom Supersonic's XB-1 demonstrator craft could become the first commercial jet to break the sound barrier since Concorde after acing its 11th test and reaching 0.95 Mach at low altitudes.

Read about the latest tests conducted with the X-66 aircraft, NASA’s experimental airliner being developed with Boeing.

An aircraft flies transonic when it reaches the range of speeds just below supersonic, which is Mach 1. Flight 11’s primary objective was to expand dynamic pressure to 383 KEAS (knots equivalent ...

Following stage separation, the first stage will land on the Just Read the Instructions drone ship, which will be stationed in the Atlantic Ocean off the coast of the Bahamas.

Prior to the supersonic flight, the XB-1 performed 11 test flights to expand the flight envelope and evaluate systems and aerodynamics through subsonic, transonic, and supersonic speeds.

Over the course of the flight test campaign, the XB-1 team systematically expanded the flight envelope through subsonic, transonic ... kinetic energy into pressure energy, allowing conventional ...
