Multi-Service Advanced Capability Hypersonic Testbed (MACH-TB) program. This initiative aims to speed up hypersoni ...

The A-HyM Hypersonic Air Master is a 170-passenger airliner concept designed to fly at over 5,600 mph and could cut the ...

Private companies like Stratolaunch are developing tech to regain the edge in the hypersonic arms race with innovations like ...

The testing capabilities of the tunnel could help researchers figure out how to fly faster and for longer durations of time, if only they can solve the problems faced when traveling five or more times ...

Hello, BBC. We're now returning and we're going to do a speed run up to the very edge of the barrier of the speed of sound and now at the moment she's reading 450 miles an hour, and we're going ...

The change in the speed of sound with temperature (about 0.5 m/s for every degree Celsius) is also similar to that on Earth. Unlike on Earth, though, sound speed and attenuation depend greatly on ...

A person fires a starting pistol. A distant observer stood 200 metres away (measured using a 20 m tape measure or trundle wheel) records the time between seeing the flash of light from the ...

But some computer models indicated that yes, they could—provided that they started out moving at faster-than-sound speed. Getting them instantaneously up to this speed would require a tremendous ...
