hy·per·son·ic

(hī'pĕr-son'ik),
Pertaining to or characterized by supersonic speeds of Mach 5 or greater. Although any speed above the speed of sound may be referred to as supersonic, speeds of Mach 5 or greater are specifically referred to as hypersonic.
[hyper- + L. sonus, sound]

The previous section has demonstrated the possibility of achieving particle grouping using acoustic method with the prerequisite that the speed of sound should be smaller than the amplitude of acoustic particle velocity.
Speed of Sound is committed to breaking the barbershop mold with cutting edge arrangements, produced by lead Ashley Wright's father, Larry Wright.
You may have heard of sonic booms - or shock waves, produced when an object crosses the speed of sound. Eustace did not feel it when he broke the sound barrier.
The changes of temperature cause a variation in the speed of sound. The speed of sound increases with temperature at the rate of 0.61 m/s/[degrees]C (Ewen, Schurter, & Gundersen, 2012).
The speed of sound is constant in the uniform material under the same circumstances such as temperature and stress state.
There are obvious advantages to ramping up to hypersonic flight, which is generally defined as anything that reaches at least Mach 5, or five times the speed of sound.
The Green Supersonic Machine jetliner pictured has an inverted-V tail design and a slender fuselage, allowing the plane to go faster than the speed of sound without causing a loud sonic boom.
Planes travelling at five times the speed of sound and passenger aircraft flying in formation could come to pass in the last part of this century, according to a report by the Institution of Mechanical Engineers (IME)
Aircraft flies at 20 times the speed of sound: Pentagon
The Pasdaran said the Khalij-e Fars missile could fly at three times the speed of sound. By comparison, the French Exocet anti-ship missile, the only missile to have struck an American warship in combat, flies at slightly less than the speed of sound.
For it to be possible to calculate the thickness, the speed of sound in the material must be known (see Equation 1).
As a part of research concerning the thermochemical studies on new working fluid pair, we present here some useful data on speed of sound and isentropic compressibility for the mixture of trimethylbenzene with tetrahydrofuran, tetrachloromethane and dimethyl sulfoxide.
