Summary:

This report develops the equations of motion for a differential roll projectile configuration with seven degrees of freedom. The dynamic equations are generated generically such that the forward and aft components are mass unbalanced. A hydrodynamic bearing exists between the forward and aft components, which couples the roll degree of freedom. A simulation investigation shows that bearing resistance and forward/aft body mass ratio are the dominant factors in determining the roll dynamics. For spin rates typical of fin-stabilized projectiles, the trajectory is essentially independent of both bearing resistance and mass ratio.
