The report reviews both theoretical and experimental investigations of the Magnus effect on arbitrary bodies of revolution. The main emphasis is on spinning projectiles at angle of attack, both with and without fins. Flow visualization measurements are used to assess the accuracy of the existing theories. Laminar, turbulent, and mixed boundary layers are considered. (Author).
An experimental investigation of the effects of spin induced distortion of the boundary-layer on a spinning cone and tangent-ogive-cylinder model for small angle of attack at Mach 2, 3 and 4 is reported. The profile of the location of boundary-layer transition has been determined completely about the surface of the models from spark shadowgraphs. These spark shadowgraphs were taken with the model mounted on an offset strut which was rolled incrementally in azimuth to reveal the entire surface of the model. Strain gage balance measurements of Magnus and normal force were made for three significantly different boundary-layer configurations--predominately laminar, predominately turbulent, tripped to turbulent--and confirm the pronounced sensitivity of Magnus to boundary-layer configuration.
