摘　　要：在C-H网格的基础上,采用Jam eson的中心差分有限体积法求解Eu ler/N-S方程,采用结构影响系数法计算结构的弹性变形,用三角元面积加权法和常体积转换法(CVT)实现流固耦合。The characteristics of static aeroelasticity for elastic wings are calculated by using H-C type grid. It is solved based on Euler/N-S equations with cell-centered finite -volume algorithm. The structure deformation is calculated by a structure influence coefficient method. We use a triangle area weight method and a constant volume transformation （CVT） method to solve the fluid-structure interaction problem. We take a swept -back wing as a numerical example to simulate the transonic aeroelastic problem.
