摘　　要：对比分析了国外已研制成功的直接力与气动力复合控制拦截弹;定性分析了直接侧向过载控制和力矩直接力控制的优缺点;探讨了复合控制拦截弹在末制导阶段是否需要滚转及转速对制导精度的影响;确定了复合控制的切换时间;推导出拦截弹所需要的脉冲发动机数量的公式,并对其详细讨论。Several successfully developed and abroad blended-control interceptors caused by lateral/aerodynamic forces were contrasted and analyzed.Both the advantages and disadvantages of immediacy-lateral-acceleration-control and moment-lateral-acceleration-control were analyzed qualitatively.Necessity of roll control for the blended-control interceptors during the terminal guidance phase and its effects on guidance accuracy were discussed.The blended control switch-time and the formula for deciding the pulse motor number were given and discussed in detail.
