Abstract: The condition of dynamic balance, the formula of dynamic non balance angle and the synthesis of dynamic balance peculiarity of two series bodies were presented. These results were applied in LM E Perigee Kick Motor (EPKM), and some useful conclusions, which can be regarded as reference to the spinning solid rocket motor design, were induced.
