Experimental Magnus Characteristics of Ballistic Projectiles with Anti-Magnus Vanes at Mach Numbers 0.7through 2.5.

摘要

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 0.7through 2.5over an angle-of-attack range from -2to 8deg. 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.
