Abstract

The dynamic stability of blunt cones at angles of attack and high supersonic Mach numbers has been investigated along lines similar to the pointed cone solution derived by the present author. The steady pressure distribution on a blunt cone is complemented with a first and second order azimuth contribution resulting from an angle of. attack displacement. The unsteady perturbation is then superimposed on the steady solution by accounting for the streamline deflection in an oscillating flow. The closed form expressions obtained for the dynamic stability of blunt cones reduce to their pointed cone counterparts once the bluntness parameter is equated to zero. The comparison between the theoretical and measured results is quite encouraging.
