Control Actuation Requirements Development for Munitions

Abstract

Enhancing munition maneuverability is a key enabling technology for long-range precision munitions that supports both range extension and terminal maneuvers. 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 work presents a methodology to analyze aerodynamic control surfaces to develop actuator requirements to ensure the control actuation system has sufficient torque to overcome aerodynamic loading and sufficient bandwidth to stabilize the projectile dynamics. These methodologies are demonstrated in this report on a gun-launched, aerodynamically stabilized, fin-controlled projectile, but are applicable to other control-surface design problems.
