| Abstract: | This paper focuses on multi-point constrained aerodynamic inverse design of wing based on adjoint method using Reynolds-Averaged N-S equation.By an effective combination of viscous flow numerical simulation,adjoint equation and gradient accurate solution,efficient grid generation and gradient optimum algorithm etc,a multi-point constrained aerodynamic inverse design method of wing is studied.The multi-point gradient is calculated by weighted average from different design points,and the design process is accelerated by means of an approximate parallel calculation model.Finally,the typical inverse design examples of wing are presented.The results demonstrate the multi-point aerodynamic inverse design method of wing has good robustness and optimization efficiency. |
