ABSTRACT	ream velocity region near the critical Reynolds number and continued in the supereritical Reynolds number region.During the high spin mode,the circumferential velocity of cylindrical models reached the magnitude of the freestream velocity.In the case of the bicone-cylinder,the spin rate was shown to be erratic,appearing sensitive to small irregularities in the nose shape.Slim triangular prisms on these cylinder surfaces,aligned with the body axis,are effective to reduce the steady state spin rate.
