Due to the influence of the elastic deformation of flexible structures, the efficiency drops constantly with the increase of the dynamic pressure, which even causes aileron reversal. 受到结构弹性变形的影响,随着飞行动压的增加,舵面的操纵效率不断下降,副翼甚至会出现操纵反效现象;
To solve the aileron reversal problem in aircraft design, an aero-elastic tailoring optimization model of composite wing for engineering requirement was established and the Pareto genetic algorithm ( PGA) based on Pareto optimal set was developed. 针对某型飞机设计过程中遇到的副翼反效问题,提出了复合材料机翼满足气动弹性要求的优化方法,构造了一种基于Pareto最优解定义的多目标遗传算法&Pareto遗传算法。
