A mathematical model of unguided-rockets’ motion in the air taking into account the deflection of the thrust and the position deviation of the center of gravity has been established. The mathematical model has been solved for a specific unguided-rocket slow spin to predict its standard trajectory and deviation trajectories; calculated results agree well with the corresponding data in the firing table. The effect of the disturbance factors on the motion stability is shown through the deviation of the graph of the angle of attack; sideslip angle and the trajectory falling points compared to the corresponding values of the standard trajectory, which does not contain deviations.
