摘　　要：详细介绍了跳跃式导弹的概念及其特点,并针对某二级导弹(一级为固体火箭发动机,二级为间隔可调双脉冲固体火箭发动机),根据跳跃式导弹的飞行特点,提出了一种飞行程序角的设计方法,给出了飞行程序角的表达式,并建立了跳跃式弹道优化模型。在跳跃式导弹概念设计阶段,在总体参数给定的情况下,弹道的设计与优化能最大限度地提高导弹的性能,利用混合遗传算法对跳跃式导弹弹道进行了较详细全面的设计与优化,并作了比较。结果表明,该方法适用于跳跃式导弹方案论证和初步设计。The concept and characteristics of skip ballistic missile were introduced in detail. Based on flight characteristics of a two-stage missile whose first propulsion was solid rocked motor and second propulsion was double pulse solid rocket motor, design method of a kind of flight program angle was put forward, and its exprssion was presented, then optimization model of skip ballistic missile was derived. With the given system parameters, ballistic design and optimization can perfectly improve properties of missile at the concept design stage of skip missile. The skip ballistic missile was designed and optimized comprehensively by using hybrid genetic algorithm, and design results of different projects were compared. The results show that the method is applicable to feasibility research and preliminary design for skip ballistic missile.
