This report explores the possibility of actively controlling a projectile with four canard lifting surfaces, equally spaced radially, with the end goals of extending range, improving terminal accuracy, and shaping the trajectory of a projectile. A description of a general mathematical model used to predict the dynamic behavior of a canard-controlled projectile in atmospheric flight is given. The model is exercised in prediction of the response of an advanced projectile currently under development. For the projectile used in this study, it is shown that the maximum range can be extended by 148 using controlled canards. It is also shown that projectile trajectories can be shaped to follow a predetermined and significantly different path than the nominal trajectory.
