Aerodynamic Model for Canard Control Actuation on a Subsonic, Gun-Launched Munition

Abstract

The US Army's modernization priority of long-range precision fires has identified a need for low-cost, high-g survivable, fast responding munition control actuation technologies. This report investigates subsonic aerodynamics of canards mounted to a complex munition configuration. The results capture regions of attached, partially separated, and fully separated flow. A static aerodynamic model of the normal force and pitching moment was developed with a dependency on the canard deflection angle. Interactions of vortices shed off the canards onto the fins were offered to explain this behavior.
