| Abstract: | 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. |
