为了探究影响变后掠翼制导炸弹滑翔增程能力的主要因素,采用粒子群优化算法分别对亚、跨、超三种投放条件下的滑翔弹道进行优化设计。固定外形与变后掠外形的优化对比结果表明:在超音速投放条件下采用变后掠翼外形具有明显增程效果,在亚音速投放条件下采用变后掠翼外形增程效果不明显。研究结果可为变后掠翼制导炸弹的总体设计提供参考。
In order to explore the main factors that affect the gliding capability of variable-pitch swept-wing guided bombs, the particle swarm optimization algorithm is used to optimize the gliding trajectory under three different deployment conditions. The comparison between the fixed shape and the variable swept profile shows that the swept-wing profile with obvious swept-over profile has the obvious extended-range effect under the supersonic deployment condition, and the effect of using the swept-back profile with extended swept profile is not obvious under the subsonic deployment condition. The results can provide reference for the overall design of variable-pitch swept-wing guided bombs.
