Three-Dimensional Boundary Layer Research as Applied to the Magnus Effect on Spinning Projectiles

Abstract

Due to Army interest in predicting Magnus effects on artillery projectiles, the Ballistic Research Laboratories are carrying out experimental and theoretical research studies of the boundary layer on yawed, spinning bodies of revolution in supersonic flow. In this paper, computed results are shown for circumferential velocity profiles and boundary layer displacement thickness for the laminar boundary layer on a yawed, spinning cone. A comparison between computed values and experimental strain gage balance measurements of Magnus force is shown to yield encouraging agreement. Surveys of the boundary layer on a yawed, spinning tangent-ogive-cylinder model have been made at azimuthal stations completely about the circumference of the model. Measurements have also been made of wall static pressure on a yawed body of revolution. Examples of these data are discussed.
