Hypersonic is, obviously, supersonic on steroids. But while "supersonic" has the clear cut definition of being faster than the speed of sound (Mach 1), hypersonic is a little fuzzier. Generally, hypersonic speeds are the point at which the molecules of air that surround the aircraft start ...

(Read 8627 times) Finally got my Mori SL1 retrofit up and running, but when I ran my first program Mach 4 isn't waiting for the spindle to come up to speed even though I have that option check marked in the spindle settings. Any suggestions?
Hypersonic speed is five times the speed of sound. Scientists measure speeds this fast with a Mach number, named for Austrian physicist Ernst Mach. Sound has a speed of Mach 1 and anything Mach 5 or above is considered hypersonic. While the speed of sound changes depending on temperature and...

An air-augmented rocket is like a normal rocket engine, except that when it gets a high enough speed, maybe at Mach two or three, it will augment the oxididation of the fuel with air in the atmosphere, and maybe go up to Mach 10 and then change back to normal rocket function. ...
How fast should the bat fly, vb, to hear a beat frequency of 225 Hz? Take the speed of sound to be 344 m/s. Speed: Speed is the ratio of distance covered by the object to time. That is, it is the rate of change of position of an ...
