Abstract:

The results of an experimental investigation of the influence of spin and nose bluntness on the boundary layer characteristics and side force of a secant ogive nose axisymmetric body are presented. Smoke visualization data for the sharp and 10, 20 and 30 spherically blunted noses were correlated with side forces measured at Reynolds numbers of 315,000 and 1,030,000, and spin rates up to 6000 rpm for angles of attack from 0 deg to 10 deg. Boundary layer flow asymmetries were correlated with the side forces measured to provide some insight into the origin of the side forces. Author
