Hypersonic — In aerodynamics, hypersonic speeds are speeds that are highly supersonic. Since the 1970s, the term has generally been assumed to refer to speeds of Mach 5 (5 times the speed of sound) and above. The hypersonic regime is a subset of the… … Wikipedia

Mach number — (mathrm{Ma} or M) (generally pronEng|ˈmɑːk, sometimes IPA|/ˈmɑːx/ or IPA|/ˈmæk/) is the speed of an object moving through air, or any fluid substance, divided by the speed of sound as it is in that substance. It is commonly used to represent an… … Wikipedia
High-hypersonic speed regime — Re Entry Speed Regime = Generally, NASA defines high hypersonic as any mach number from 10 to 25 and Re entry speeds as anything greater. Aicraft operating in this regime are the Space Shuttle and various space planes in future development.… … Wikipedia

Aerodynamics — is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is closely related to fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is… … Wikipedia
Non-rocket spacelaunch — Non rocket space launch (NRS) is a launch into space where some or all needed speed and altitude is provided by non rocket means, rather than simply using conventional chemical rockets from the ground. A number of alternatives to rockets have… … Wikipedia
