Abstract
THE supercritical stability margin of inward-turning scoop inlets applicable to dual-mode ramjet engines has been greatly enhanced by the incorporation of a series of cowl vent slots just downstream of the inlet throat. Data has been obtained over a range of Mach number, angle of attack, and roll angle, using two single-module inlet models. A data base has been established to characterize the effect of varying available slot spill area on the stable operating range of the inlet and on the maximum inlet air capture and pressure recovery.
