摘要
为寻找到可变后掠翼飞机的最佳变后掠规律,利用CATIA生成不同后掠角模型,使用Fluent模拟不同高度的环境并利用遗传算法得出最佳的变后掠规律,最后将计算数据进行拟合分析。研究结果表明,在不同高度下,最佳变后掠规律大体趋势相似,但5 000 m时优势略明显。这个结论为今后可变机翼无人机的设计提供了一定的依据。
To look for optimal variable sweep rules of variable sweep aircraft,models with different swept angle was built with CATIA,environment of different altitudes was simulated with Fluent,the optimal variable sweep rules was obtained by using the environment application genetic algorithm,and the computed data was fitted. Analysis results show that the tendency of optimal variable sweep rules are similar atdifferent altitudes,and the one at 5 000 meters is better. This result provides basis for the design of variable sweep wing UAV in the future.
