摘要

本文介绍了在两种跨音速巡航流动条件下对通用公务喷气机机翼进行的单学科和多学科形状优化。所进行的研究基于两个基于梯度的高保真优化工具,并采用了辅助方法(同时采用离散和连续方法)。通过这两种工具计算出的单学科和多学科耦合灵敏度导数与有限差分进行了比较和验证。证明了在基于邻接法的优化中不做冻结湍流假设的重要性。然后,介绍并讨论了一系列优化运行,从具有刚性结构的纯空气动力学运行到探索相关学科之间权衡的空气结构运行。此外,还研究了以空气动力学标准优化机翼,然后进行气动结构修剪的中间方案。

Discrete and Continuous Adjoint-Based Aerostructural Wing Shape Optimization of a Business Jet
This article presents single- and multi-disciplinary shape optimizations of a generic business jet wing at two transonic cruise flow conditions. The studies performed are based on two high-fidelity gradient-based optimization tools, assisted by the adjoint method (following both discrete and continuous approaches). Single discipline and coupled multi-disciplinary sensitivity derivatives computed from the two tools are compared and verified against finite differences. The importance of not making the frozen turbulence assumption in adjoint-based optimization is demonstrated. Then, a number of optimization runs, ranging from a pure aerodynamic with a rigid structure to an aerostructural one exploring the trade-offs between the involved disciplines, are presented and discussed. The middle-ground scenario of optimizing the wing with aerodynamic criteria and, then, performing an aerostructural trimming is also investigated.
