XB-1 achieved Mach 0.95 during its most-recent test flight on Jan. 10, according to Boom Supersonic. Boom founder and CEO Blake Scholl poses by a model of the XB-1 on July 23, 2024 in Farnborough ...
The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or impossible.
Manned by Boom Supersonic's chief test pilot Tristan "Geppetto" Brandenburg, the XB-1 launched in the early hours of Tuesday, reaching an altitude of 35,290 feet and accelerating to speed Mach 1. ...
Boom Supersonic’s XB-1 aircraft climbed over 35,000ft on Tuesday before accelerating to Mach 1.1 speed and then breaking the sound barrier in three high-speed runs spanning 35 minutes over the ...
The Prandtl–Glauert transformation assumes linearity (i.e. a small change will have a small effect that is proportional to its size). This assumption becomes inaccurate toward Mach 1 and is entirely invalid in places where the flow reaches supersonic speeds, since sonic shock waves are instantaneous (and thus manifestly non-linear) changes in the flow.

It was not until World War II, when aircraft started to reach the limits of the sound barrier — although without successfully breaking the barrier into supersonic speed — that the term came ...
A vapor cone (also known as a Mach diamond, [1] shock collar, or shock egg) is a visible cloud of condensed water that can sometimes form around an object moving at high speed through moist air, such as an aircraft flying at transonic speeds. When the localized air pressure around the object drops, so does the air temperature.
