Abstract : Using momentum integrals, an expression for the boundary layer displacement thickness is obtained from the unsteady equations of motion on a sharp, right, circular cone oscillating about a small mean angle of attack in hypersonic flow. The effects of the boundary layer displacement on the stability derivatives for small pitching oscillations were considered for an insulated cone with a Prandtl number of 1. Numerical results for a 10 degrees half-angle cone indicate that the viseous contributions to the stability derivatives may be considerable for low Reynolds numbers at high Mach numbers. (Author)
