| Abstract: | In this paper,the multidisciplinary aerodynamic-structure optimization design method of elastic wing based on response surface methodology is performed.M6 wing is chosen as the base wing.The design results show that the lift-to-drag ratio has increased by 9.25% and the structural weight has reduced by 4.84%,the response surface methodology is accurate enough to satisfy the engineering requirement.It can be concluded that the present method is effective and feasible,and is applicable for engineering practice due to its high design capability. |
