The nonlinear coning motion equations in body coordinates on the force moment coefficients of low speed spinning rocket were obtained based on the dynamics equations.
根据滚转火箭弹的动力学方程，给出了在弹体坐标系下无控低速滚转火箭弹在被动飞行段的锥形运动方程组。

It is demonstrated that there exists a part of high pressure on the body surface of the rocket near the fore-located nozzles, thus forming a overturning moment.
