supersonic inlets
An inlet for a supersonic aircraft, on the other hand, has a relatively sharp lip. The inlet lip is sharpened to minimize the performance losses from shock waves that occur during supersonic flight.
Supersonic
Speeds above the speed of sound.
The first aircraft in the world to break the sound barrier was the Bell X1. On the 14 October 1947 it reached 670mph at 42000feet (Mach 1.015).
SUPERSONIC - Speed of flight at or greater than Mach 1.0; literally, faster than the speed of sound.
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.
Supersonic Flight
Flight at speeds greater than the speed of sound, which varies according to altitude but which is more than 700 miles per hour at sea level.
[edit] Supersonic
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.
Supersonic: Mach 1.2 - Mach 5
Hypersonic: Greater then Mach 5
Most airliners currently travel around anywhere from Mach 0.6 - Mach 0.9. Military jets of course can travel in some cases at hypersonic speeds.
SUPERSONIC - Speed in excess of that of sound.
SV-VS - Soviet Military Aviation Forces (Sovietskiye Voenno-Vozdushnye Sily).

The supersonic, variable-wing B-1 bomber is able to carry more armament (up to 52,160 kg/115,000 lb) than any other combat aircraft. It was designed to replace the B-52 as the primary nuclear bomber of the United States.
Supersonic:760-3500 MPH. Hypersonic: 3500-7000 MPH Roll To roll the plane to the right or left, the ailerons are raised on one wing and lowered on the other. The wing with the lowered aileron rises while the wing with the raised aileron drops.
Supersonic conditions occur for Mach numbers greater than one, 1 . Compressibility effects are important for supersonic aircraft, and shock waves are generated by the surface of the object.

(a) subsonic airfoil (b) supersonic airfoil
The most forward point of the airfoil is defined as the leading edge and the most rearward point is defined as the trailing edge.
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.
For a very different reason: to slow the airflow so that the compressor can operate subsonically even when the aircraft is close to sonic speeds-or even supersonic! ...
Too much instability is also an undesirable characteristic, except where an
extremely manoeuvrable aircraft is needed and the instability can be continually
corrected by on-board 'fly-by-wire' computers rather than the pilot, such as a
supersonic air ...
For subsonic airplanes, dynamic effects may generally be handled by correcting these static characteristics suitably. However, it should be noted that airplanes with supersonic capabilities require more careful consideration of the dynamic effects ...
It has chapters like Development of Aerodynamic Pitching Moments, Planform Effects and Airplane Drag, Turbojet Operating Characteristics, High Speed Aerodynamics - Concepts and Supersonic Flow Patterns, Stability and Control.
