Abstract

Six scramjet inlet models were tested in a Mach 4 wind tunnel. Wall and pitot pressure were measured and schlieren photographs were taken. Parameters of these models are side-plate sweep angle, contraction ratio, and cowl geometry. The shock pattern inside one of the models, as shown by schlieren photographs, coincides with the calculations. Both mass-capture ratio and total pressure recovery are 50-70%. There seems to be a better sweep angle and a better cowl length for maximum total pressure recovery.
