采用基于目标函数的非结构网格离散伴随方法进行机翼多约束单点和多点组合无粘减阻优化设计。通过基于目标函数的离散伴随模型计算目标函数梯度,考虑多种典型几何和气动约束,采用拉格朗日方法求解多约束优化问题,利用径向基函数进行几何模型参数化。对M6机翼单点和多点组合优化展示了本文优化设计系统的有效性,能够较好地满足工程实际需求。
The objective function-based unstructured grid discrete adjoint method is used to optimize the design of multiple drag-free and drag-free combinations of the wings. The objective function gradient is calculated by using discrete adjoint model based on objective function. Many typical geometric and aerodynamic constraints are considered. The Lagrange method is used to solve the multi-constrained optimization problem and the radial basis function is used to parameterize the geometric model. The optimization of single-point and multi-point combination of M6 wings shows the effectiveness of this optimization design system and can meet the actual engineering requirements.
