Performance of two axisymmetric air intakes are compared at conditions suitable for Mach number range from 2 to 8.First is the Busemann intake and second is the reversed isentropic nozzle. The isentropic nozzle is built by the method ofcharacteristics. The contour of this nozzle is taken as a compression surface for the incoming flow. Performances of these twointakes are compared by comparison of both viscous and inviscid CFD calculations at Mach 6. Viscous flow calculations showthat the total pressure recovery in compression section is 0.8316 in the Busemann intake and 0.869 in the reversed isentropicnozzle intake.
