Generally, NASA defines high hypersonic as any Mach number from 10 to 25, and re-entry speeds as anything greater than Mach 25. Aircraft operating in this regime include the Space Shuttle and various space planes in development. 【参考译文】一般来说,NASA将高高超音速定义为从10到25的任何马赫数...

The main idea is to exploit the indirect measurement of the aerodynamic forces applying on a control surface which are clearly related to the aircraft airspeed. Focusing on those aircraft equipped with a Fly By Wire system, at least one actuator is installed on each of the control surfaces; ...
to travel around the aircraft structure. At the Critical Mach number, local airflow in some areas near the airframe reaches the speed of sound, even though the aircraft itself has an airspeed lower than Mach 1.0. This creates a weakshock wave. At speeds faster than the Critical Mach number...
The meaning of MACH NUMBER is a number representing the ratio of the speed of a body (such as an aircraft) to the speed of sound in a surrounding medium (such as air). How to use Mach number in a sentence.
Mach number is useful because the fluid behaves in a similar way at the same Mach number. So, an aircraft traveling at Mach 1 (340.3 m/s, 761.2 mph, 1,225 km/h) will experience shock waves in much the same manner as when it is traveling at Mach 1 at 11,000 m (36,000 ft), ...

Hypersonic:When the speed of an object is much higher than the speed of sound the flow is called hypersonic. The range of Mach number is five to ten in this case. The design of aircraft is done according to the Mach number to get the best result. Also, we know that sound moves in ...
