Non axial thrusts produced by solid rocket motors during three axis stabilized attitude control have been determined from ascent experience on twenty three Burner II, Burner IIA and Bock 5D-I upperstage vehicles. A data base representing four different rocket motor, designs three spherical and one extended spherical) totaling twenty five three-axis stabilized firings is generated. Solid rocket motor time varying resultant and lateral side force vector magnitudes, directions and total impulses, and roll torque couple magnitudes directions, and total impulses are tabluated in the appendix. Population means and three sigma deviations are plotted in the main body of the paper. Existing applicable ground test side force and roll torque magnitudes and total impulses are evaluated and compared to the above experience data base. Within the spherical motor population, the selected AEDC ground test data consistently under estimated experienced motor side forces, roll torques and total impulses. (Kursetz)
