Abstract
The characteristics of a supersonic bump-type inlet with a bleeding system were numerically studied to examine the influence of boundary-layer bleeding in controlling shock wave/boundary layer interactions. The bump-type inlet, which is based on a conventional ramp-type inlet, was designed for two oblique shock waves and a terminal normal shock wave followed by a subsonic diffuser. A bleed slot connected to a plenum chamber was installed under the root of the normal shock wave. As a consequence, the bleeding mass flow extracted from the main inlet stream to the plenum chamber was controlled. The numerical simulations conducted in this study showed that the bleed slot could enhance the performance of the bump-type inlet.
