Control Surface Design Analysis for Munitions

Abstract

Enhancing munition maneuverability is a key enabling technology for both range extension and terminal maneuvers of long-range precision munitions. One approach to munition maneuverability is to deflect control surfaces to achieve body attack angles that generate lift from the body and other aerodynamic surfaces. This report presents a methodology to analyze aerodynamic control surfaces to determine effectiveness at generating a pitching or yawing moment on a projectile to attain an angle of attack that produces significant lateral accelerations in flight. The methodology demonstrated in this report is for a gun-launched, aerodynamically stabilized, fin-controlled projectile, but is applicable to other control surface design problems.
