Boom about to go supersonic
The commercial supersonic airplane company Boom is on the verge of flying its XB-1 test vehicle faster than the speed of sound.
The company has been doing a regular test flight program, each time increasing the plane’s speed.
During the latest 44-minute flight at an altitude of 29,481 ft (8,986 m) with Chief Test Pilot Tristan “Geppetto” Brandenburg at the controls, the prototype aircraft reached transonic speed. That is, flight so close to Mach 1 that some areas of airflow over the airframe exceed the speed of sound.
It’s also the point where the XB-1 was subjected to a maximum dynamic pressure of 383 Knots Equivalent Air Speed (KEAS), which is a pressure on the fuselage and wings greater than what it would experience when flying supersonic at Mach 1.1.
In short, XB-1 pushed what was once called the Sound Barrier.
Next step: break the sound barrier.
At the completion of this testing the company will then begin manufacture of its full scale supersonic passenger plane, dubbed Overture, that will carry up to 80 passengers and will sell to airlines. It already has contracts and financial support from a number of major airlines, including United and Japan Airlines.
