摘要
针对末端近距防御的特殊需求,研究了低成本主动防护系统拦截导弹设计方法。分析了拦截导弹的总体设计方案,利用工程算法和CFD平台设计优化了拦截导弹的气动外形,研究了侧向喷流干扰并提出了抑制措施,提出了拦截导弹控制资源分配方案并设计了非线性控制策略。建立了六自由度拦截对抗模型,利用蒙特卡洛方法分析了设计方法的有效性和鲁棒性。研究结果表明,在简易制导条件下,采用轨控脉冲发动机非线性操纵方式可满足拦截导弹的总体需求。
To satisfy terminal short-distance defense requirement, design methods for low-cost intercept missile of active protection system were presented. The general scheme was analyzed, and project methods and CFD platform were used to design and optimize the airframe of missile. The disturbance of lateral jet was simulated and analyzed, and the restrained approach was derived. Then the control resources arrangement was presented,which was suited with nonlinear control measures. Six-DOF intercept model was established, and the validity and robustness of previous design method were tested by Monte-Carlo simulation. The result shows that under the conditions of simple guidance, utilizing divert pulse motor in a nonlinear way can satisfy the general requirements.
