| 摘 要： | 本文提供了一个具有复合材料蒙皮、金属骨架的中等展弦比、中等后掠角机翼的气动弹性剪裁计算结果。采用各向异性平面应力复合材料元素,使用Tsai-Hill准则,进行满应力设计,在此基础上,用直观准则（导数均匀准则）法进行了颤振速度和副翼效率优化设计。

| Abstract: | Some results of aeroelastic tailoring of a sweptback wing with medium aspect ratio and composite skin and metal frame are presented. By use of Tsai-Hill criterion the strength critical elements were resized. Then the flutter or aileron effectiveness critical elements were redesingned by use of the uniform-flutter velocity or uniform-aileron effectiveness derivative criteria. By a few steps of resizing, satisfactory results are obtained. |

| Keywords: | aeroelastic tailoring composite structure flutter divergence |
