【摘要】 为研究双脉冲发动机参数对小型空地导弹外弹道性能的影响，通过建立导弹六自由度变质量模型和单助推、双脉冲发动机推力模型，开展小型空地导弹外弹道仿真研究。弹道计算结果表明对于近程低空空地导弹，双脉冲发动机脉冲间隔时间、发动机装药比对弹道射程的影响强于发动机推力比。基于粒子群优化算法对双脉冲发动机参数与控制参数开展联合优化，结果显示采用联合优化方案对小型空地导弹的射程提升了27.16%,对不同距离目标的攻击弹道末速提升了13.97%到26.11%。更多还原

【Abstract】 To study the influence of dual-pulse engine parameters on the external ballistic performance of smallair-to-ground missiles, the external ballistic simulation of small air-to-ground missiles was carried out by establishing a six-degree-of-freedom variable mass model and a single-booster and double-pulse motor model.The results indicate that for short-range low-altitude air-to-ground missiles, the pulse interval and propellant ratio of the dual-pulse motor have moreevident effect on the range and the engine thrust ratio has less.Based on the particle swarm optimization algorithm, the motor parameters and control parametersare jointly optimized, and the results show that the joint optimization scheme increases the range of small air-to-ground missiles by 27.16%, and the terminal velocity of attack trajectory against targets at different distances increases by 13.97% to 26.11%.更多还原
