This paper describes a computational study to understand the roll behavior of a canard-controlled projectile. Numerical simulations were performed for this projectile with roll control maneuvers using advanced computational fluid dynamics and coupled aerodynamics/rigid-body dynamics techniques. Roll control algorithms were formulated based on aerodynamic model assessment and parameter estimation. Coupled techniques were validated against wind tunnel experiments for roll control maneuvers. Overall, computed roll control results matched well with the wind tunnel data, indicating that the coupled calculations capture the relevant physics observed in the experiment. This study demonstrates that relatively simple aerodynamic models can be used to represent complex aerodynamic phenomena for these configurations at Mach 0.49. Additionally, roll controllers with favorable performance over a wide range of conditions can be designed based on these models of the aeromechanics.
