Pressure Measurements on a Spinning Wind Tunnel Model by Means of Telemetry.

Abstract

The Magnus force is a side which exists on spin stabilized projectiles at angle of attack. Although its absolute magnitude is small, it has a destabilizing effect and as such is of interest to projectile designers. A large part of the Magnus force arises from an asymmetric pressure distribution caused by the distorted boundary layer. Experimentally, the Magnus effect has always been measured in terms of force by using strain gage balances. This paper discusses a possible technique for measuring the pressure distribution about a spinning body and obtaining the force by integration. It would also serve as a check for three dimensional boundary layer calculations presently available.
