Supersonic Speed: A speed greater than the speed of sound through the medium concerned. The speed of sound in air is about 770 m.p.h. at sea level, falling to about 660 m.p.h. at 36,000ft.
At supersonic speeds an oblique shock exists in front of the leading edge of the wing. The velocity component perpendicular to the shock is different upstream and downstream of the shock.
An ongoing dispute with India prevented Concorde from reaching supersonic speeds in Indian airspace, so the route was eventually declared not viable and discontinued in 1981.
For high supersonic speeds, 3 , aerodynamic heating also becomes very important for aircraft design.
For speeds greater than five times the speed of sound, M 5, the flow is said to be hypersonic.
This 45 feet long, liquid-fuelled rocket carried a one ton warhead, and was capable of supersonic speed and could fly at an altitude of over 50 miles. As a result it could not be effectively stopped once launched.
at subsonic speed, the magnitude of the aerodynamic moment remains nearly
constant even when the angle of attack changes.
This location is called the wing's Aerodynamic Centre AC.
(At supersonic speed, ...
Even though the fighter plane can fly much faster than the speed of sound, the air going into the engine must travel less than the speed of sound for high efficiency. Therefore, the airplane inlet slows the air down from supersonic speeds.
Supersonic Planes which travel faster than Mach 1 (or the speed of sound) are traveling at supersonic speeds. An example of this speed regime is the Concorde. The speed range is 760 - 3500 MPH or Mach 1 - Mach 5.
