Integrated Aerodynamic/Structural Design Optimization for Wing of Trunkliner
【摘要】 为了妥善处理机翼设计中气动和结构之间的矛盾 ,提高飞机的整体性能 ,对干线客机机翼气动 结构综合设计方法进行了研究 .将非等熵全位势方程CFD方法与基于工程梁理论的机翼结构设计方法相结合进行分析计算 ,用序列二次规划法对全局敏度方程所构造近似系统进行优化 ,通过对一系列近似系统的优化 ,逼近综合设计的最优解 .最后以一种干线飞机的机翼气动 结构综合设计为算例验证了这一设计方法的可行性
【Abstract】 An integrated aerodynamic/structural design method for a wing of trunkliner is studied to obtain a tool for tradeoff between the contradictory demands of aerodynamic and structural design. Non-isentropic potential equation CFD method and beam theory model are introduced into the analysis of the design. A sequence of approximations constructed using GSE are optimized by SQP method to approach the optimum solution. The wing of a trunkliner is optimized as an example to demonstrate the feasibility of the method.
