This paper studies the leading-edge receptivity of 3-D hypersonic boundary layers to freestream acoustic disturbances for Mach 15 mean flows over a blunt 2:1 elliptical cone. The wave modes induced in the boundary layer by the freestream disturbances are studied based on a numerical simulation of the Navier-Stokes equations and a locally parallel linear stability analysis.
