变后掠翼制导炸弹滑翔弹道优化设计

The Optimization Design of Glide Trajectory for Guide Bomb with Morphing Swept Wings

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 improve the gliding ability of the guide bomb with morphing swept wings,an improved particle swarm optimization （PSO） method is adopted to achieve the optimization trajectory under the different initial conditions of subsonic,transonic and supersonic.The optimization results between fixed shape and variable shape show that the morphing swept wings has significant extended-range effect under the initial conditions of supersonic,but they hardly extend range under the initial conditions of subsonic.The results can serve as a reference to the overall design of guide bomb with morphing swept wings.
