Dynamic balance in spinning solid rocket motor

对动平衡条件、动不平衡角计算公式及两串联物体动平衡合成进行了详细的理论推导。将上述结果应用于EPKM (LM -EPerigeeKickMotor) ,得出了一些有益结论 。

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