Abstract:

An experimental investigation was conducted to determine static- stability and Magnus characteristics of three spin-stabilized ballistic shell configurations with small anti-Magnus vanes on the boattail. The models slightly larger than full scale were tested at Mach numbers 0.7 through 2.5 over an angle-of-attack range from -2 to 8 deg. Results are presented showing the effects of spin, Mach number, angle of attack, and anti-Magnus vanes. These results show that the vanes were effective in reducing both Magnus force and moment for two of the basic configurations and that the canted 7.2-deg vanes were more effective than the straight vanes.
