针对弯头双锥机动弹头 ,采用内伏流牛顿方法和Euler方程数值方法计算气动力 ,并与六自由度弹道方程组耦合计算 ,分析了再入过程中的螺旋弹道特性以及滚转角速度和弹头几何参数等对螺旋弹道的影响 ,最后分析了利用控制质心横向运动来控制弹头滚转的方法。 Aiming at the elbow biconical mobile warhead, aerodynamic force is calculated by the Newton method of in-fluvial flow and the numerical method of the Euler equation. Coupled with the six-degree-of-freedom ballistic equations, the characteristics of the spiral trajectory, the angular velocity of the roll and the warhead geometry Parameters and other effects on the spiral trajectory, the final analysis of the use of control center of mass lateral movement to control the method of warhead roll.
