Magnus Forces on Spinning Supersonic Cones -Part I: The Boundary Layer

This is the authors' abstract. We don't add key points for this paper.

A detailed investigation of the laminar boundary layer flow over a spinning right circular cone at small angle of attack has shown that there are at least four significant forces contributing to the Magnus force on the cone. In order to calculate these forces a novel numerical method has been developed which can calculate these small forces over a wide range of flow parameters. The flow conditions have a large influence on the relative magnitude of the Magnus force components and there can be significant cancelling of the various components. An investigation has also been carried out to show that boundary layer calculations are valid at small angles of attack and that 'boundary region' techniques are not needed until moderate angle of attack.
