Abstract

Hot-wire meassurements are made in the laminar boundary layer of a flat plate and a cone at Mach 5. These measurements do not show the expected dominance of high-frequency second-mode instabilities, predicted by linear stability theory and found in other experiments. The growth of natural disturbances within a broad frequency band up to 50 kHz on the flat plate and up to 200 kHz on the cone can be observed.
