Three Dimensional Boundary Layer Studies as Applied to the Magnus Effect on Spinning Projectiles,
Abstract
A combined theoretical-experimental study of the Magnus effect on yawed, spinning projectiles was discussed. The overall objective of this effort is to develop a method for computing Magnus effects that could be used in the design of artillery projectiles. Numerical techniques have been developed for computing: (1) the three dimensional turbulent boundary layer development over a yawed, spinning body of revolution; (2) the three dimensional boundary-layer displacement surface for an arbitrary body of revolution; and (3) the three dimensional inviscid flow field over a yawed, pointed body of completely general configuration with no plane of symmetry. The computations have been compared to experimental measurements of Magnus force and turbulent boundary layer profile characteristics. It is further emphasized that effects due to nose bluntness and protuberances such as rotating bands must be examined before the computation capability can be considered to have the full capability desired to artillery projectile design studies.
