| 摘 要： | 基于一种伸缩弹翼改变巡航导弹外形的概念,提出超声速巡航与亚声速盘旋相结合的飞行任务,使用Missile Datcom作为气动计算的工具,分别对固定翼、两级伸缩翼和三级伸缩翼的外形参数进行了优化,使三种不同弹翼导弹完成相同飞行任务的燃料消耗分别最小,优化方法选取遗传算法与模式搜索法相结合的混合优化策略.优化结果显示,两级、三级伸缩翼巡航导弹相对固定翼巡航导弹燃料消耗量分别减少7.8%和12%,表明伸缩弹翼有效提高了巡航导弹在整个飞行任务中的气动性能.

| Abstract: | Based on the morphing concept of telescopic wings,this paper chose a flight mission which is comprised of supersonic cruise and subsonic loiter.With aerodynamic coefficients calculated by Missile Datcom,the shapes of the fixed wing and telescopic wings were optimized through the hybrid optimization strategy coupling genetic algorithm with a pattern search method.For the designed mission used in these studies,two stages and three stages telescopic wings cruise missiles were found that could complete the miss... |
