Boundary Layer and Side Force Characteristics of Non-Spinning and Spinning Axisymmetric Bodies.

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)
