Air-breathing hypersonic systems are particularly sensitive to the inflow state of air and the shock structure generated from the inlet surface. Researchers at Purdue University have developed OIWPS, a stream-tracing method for designing inlet geometries to address these problems. OIWPS uses the desired post-shock and free stream Mach numbers to optimize the upper forebody and lower cowl of the inlet. The resulting inlets are shape-transitioned, inward-turning, mixed contraction, and self-startable. This technology's primary application is in the development of the next generation of hypersonic vehicles for civilian and military use.
