A supersonic inlet employs relaxed isentropic compression to improve net propulsive force by shaping the compression surface of the inlet. Relaxed isentropic compression shaping of the inlet compression surface functions to reduce cowl lip surface angles, thereby improving inlet drag characteristics and interference drag characteristics. Supersonic inlets in accordance with the invention also demonstrate reductions in peak sonic boom overpressure while maintaining performance.
1. A supersonic inlet designed for flight at a specific and pre-determined Mach number, the supersonic inlet comprising: a compression ramp and cowl;said cowl having an upstream lip;said compression ramp having an upstream straight compression ramp having a leading edge or an apex, connected downstream with a concave surface relative to the flow, said concave surface connected downstream with a straight surface;said leading edge or apex having an angle, and said cowl lip is positioned such that an inclined shock wave generated at said leading edge or ape...
