A supersonic inlet includes a relaxed isentropic compression surface to improve net propulsive force by shaping the compression surface of the inlet to defocus the resulting shocklets away from the cowl lip. Relaxed isentropic compression shaping of the inlet compression surface functions to reduce the cowl lip surface angle, 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 overall engine perf...
1. An external compression inlet for use in a jet engine of the type including a compression surface having a foremost point and a cowl lip characterized by a cowl lip angle, the inlet comprising, in cross section: an initial segment disposed at a leading edge of said compression surface and inclined at a constant, initial turn angle α with respect to a free stream, said initial segment being configured to produce, at a predetermined design cruising speed, a bow shock which intersects an intersection point proximate said cowl lip; anda continuously curve...
