The interaction of acoustic and entropy waves with an oblique shock occurring upstream of a cone is investigated. The three-dimensional supersonic Ma = 5.9 flow over a 30° half angle cone at prescribed acoustic and entropy waves is computed and the wall pressure fluctuations are sampled to quantify the receptivity with respect to the incident waves. Two cone configurations with different tip radii are considered to determine the influence of the tip radius on the wall pressure fluctuations. It is shown that the receptivity to both types of waves shows a weak dependence on the cone tip radius that decays in the downstream direction.
