【摘要】 为了进一步提升多目标拦截器（MOKV）固体姿轨控系统的能量管理的效能，获得其质量最小的总体方案，提出一种基于制导策略的MOKV动力系统设计方法。首先，提出一套基于线性协方差分析的多脉冲制导策略评估方法，可快速解析地确定每次机动所需的最大速度增量；然后，确定了对称双燃烧室三脉冲固体姿轨控动力系统的布局方案，具有结构简单、易于控制的特点；随后，给出了动力系统的性能参数模型和质量模型，建立了基于制导策略的动力系统优化设计流程。经过相图法迭代优化，可得到满足尺寸约束条件下的质量最优解，并进一步给出了子拦截器的设计指标。最后，针对典型应用场景开展案例设计并通过蒙特卡洛随机测试评估脱靶量。结果表明，案例MOKV可携带12枚子拦截器，总质量为49.43 kg，轴向尺寸为540.7 mm，径向尺寸为231.9 mm。三次脉冲点火后，MOKV最大脱靶量从千米级缩小至百米级直至十米级，可实现子拦截器精准拦截目标。所提出的理论与方法可为MOKV的高效能量管理和轻质化设计提供有力支撑。更多还原

【Abstract】 To further improve the energy management efficiency of the solid divert and attitude control system of the multi-objective kill vehicle(MOKV),and obtain the minimum overall mass scheme,a propulsion system design method for MOKV based on the guidance strategy was proposed. Firstly,a rapid evaluation method for the multi-pulse guidance strategy based on linear covariance analysis was proposed to determine the maximum velocity increment required for each maneuver. Then, the layout scheme of the three-pulse solid divert and attitude control propulsion system with a symmetrical dualcombustion chamber was determined, which featured a simple structure and high controllability.Subsequently,performance parameter and mass models for the propulsion system were established,and an optimal design process of the propulsion system based on the guidance strategy was developed. Through iterative optimization using phase diagram analysis,the mass-optimized solution satisfying size constraints can be obtained, and the design criteria for the sub-interceptors were further provided. Finally, a case design was carried out for typical application scenarios, and the miss distance was evaluated through Monte Carlo random test. The case results showed that the MOKV can carry 12 sub-interceptors,with a total mass of 49.43 kg,an axial dimension of 540.7 mm,and a radial dimension of 231.9 mm. After three pulse ignitions,the maximum miss distance of the MOKV was reduced from the kilometer level to the hundred-meter level and even the ten-meter level,which can achieve precise interception of the target by the sub-interceptors. The theory and method proposed can provide a strong support for the high-efficiency energy management and lightweight design of MOKV.更多还原
