摘要

摘要: 为提高动能拦截器变轨拦截能力,考虑目标与拦截器相对距离、相对速度等因素,构建了拦截器零控脱靶量、轨控发动机内弹道、发动机质量与尺寸等优化模型,将遗传算法和Powell算法相结合进行轨控发动机不确定性优化设计.应用算例表明,采用优化设计后的轨控发动机,拦截器可修正的最大零控脱靶量至少提高17.9%,不确定性因素的影响更加明确,为动能拦截器总体优化设计提供了参考.

Abstract: To improve the transport and intercepting capability of interceptor considering the relative distance and velocity between target and interceptor, etc, the zero-effort-miss model of interceptor, the internal ballistic model and the mass & size model of trajectory-control engine were established to optimize the trajectory-control engine. The genetic arithmetic combined with Powell method was also adopted in the optimization design of trajectory-control engine. The zero-effort-miss eliminated by trajectory-control engine could improve not less than 17.9% as proved by the optimization design case, and the influence caused by uncertain factors was more explicit, so the method might be applied to the optimization design of interceptor.
