Experimental Magnus Characteristics of Ballistic Projectiles with and without Anti-Magnus Vanes at Mach Numbers 1.5 Through 2.5
Abstract
An experimental investigation was conducted to determine static- stability and Magnus characteristics of four spin-stabilized ballistic shell configurations with and without small anti-Magnus vanes on the boattail. The models (slightly larger than full scale) were tested at Mach numbers 1.5, 2.0, and 2.5 over an angle-of-attack range from -2 to 8 deg. The Reynolds number, based on a model diameter of 5.2 in., was 1,700,000, and the spin parameter ranged from zero to 0.25 radians. 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 generally more effective than the straight vanes.
