hypersonic speed:

see aerodynamicsaerodynamics,
study of gases in motion. As the principal application of aerodynamics is the design of aircraft, air is the gas with which the science is most concerned. Although aerodynamics is primarily concerned with flight, its principles are also used in designing automobile

AFPN) -- For an aircraft to achieve hypersonic speeds, ranging from 6,000 to 15,000 mph (Mach 9 to Mach 22), and reach altitudes between 100,000 to 150,000 feet, it needs an airframe structure designed to survive intense heat and pressure.
They understand how this happens at slower speeds, but they still are grappling with which factors influence it at hypersonic speeds.
The mission marked the first time a scramjet engine had successfully powered a vehicle in flight at hypersonic speeds.
NASA is one step closer to developing an inflatable spacecraft heat shield that could survive the superheated hypersonic speeds of entry into a planetary atmosphere, following the successful July 23 launch of the Langley-led Inflatable Reentry Vehicle Experiment 3 (IRVE-3).
The X-51 removed any future doubt that a scramjet engine can power a vehicle at hypersonic speeds and accelerate it through the atmosphere," Lewis said.
NASA officials on Monday were putting together a board to investigate Saturday's rocket failure, which destroyed the pilotless, 12-foot-long X-43A that the agency hoped to fly at hypersonic speeds over the Pacific Ocean.
