摘要

摘要: 为解决后掠翼设计中减重与副翼效率降低的矛盾，进行了后掠翼复材蒙皮的气弹剪裁设计。针对复材蒙皮的铺层比例和厚度等设计参数，进行了变参分析，获得了设计参数对舵效的影响规律。根据所得参数影响规律，提出了在保持舵效不降低基础上进行蒙皮减重的工程优化设计策略。在此策略指导下，以复材蒙皮的铺层比例和厚度作为设计变量，同时考虑严重载荷工况下的静强度约束以及典型飞行状态下的舵效约束，以蒙皮重量最轻为目标函数，采用MSC.Nastran SOL 200模块成功进行了后掠翼复材蒙皮气弹剪裁设计。

Abstract: The aim of the present study is to solve the control effectiveness problem in aft swept wing design by aeroelastic tailoring of the composite skin. Parametric analysis was carried out for the ply stacking ratio and thickness of the composite skin to study the influence on the static strength and control effectiveness. Based on the parametric trends obtained, a novel engineering strategy was proposed to reduce the weight of composite skin while keeping the control effectiveness. With such strategy, ply stacking ratio and the composite skin thickness were selected as design variables, and the objective function was the lowest skin weight considering the static strength constraint under critical load case and the control effectiveness constraint under typical flight condition. The optimization problem was solved successfully by MSC.Nastran SOL 200 solver for aeroelastic tailoring of an aft swept wing with composite skin.
