1. 3-0 Method of Characteristics (MOCHA):
2. Th NASA developed 3-0 MOCHA program of Vadyak et ali will- be used to compute the inviscid core flow of the inlet. The program features discrete fitting of the external and the internal shock wave system. Far cases in which the internal shock system is "weak," f;hese shocks can be captured which tends to smear" the property discontinuities at shocks. I t is assumed that both the centerbody and cowl contours are "smooth" and have continuous first partial derivatives.
