Many projectiles used by the Army are slender bodies of revolution which are launched at high spin rates. Magnus forces and moments are generated by the distorted boundary layer which results from a spinning body at angle of yaw. The Ballistic Research Laboratory (BRL) is conducting and supporting theoretical and experimental Magnus research efforts. The theoretical efforts involves: 1) numerical calculation of the fully three-dimensional boundary layer with the added complication of interaction between surface spin and cross flow velocity; 2) three-dimensional inviscid flow calculations over a body plus boundary layer displacement surface with no plane of symmetry. Several types of experimental data, such as surface pressures, Magnus forces, boundary layer surveys, flow visualization, and skin friction, were obtained to evaluate and provide guidance to the theoretical effort. Comparison of the theory to expermental data shows the agreement to be very good. (Depo)
