Abstract�� A fluid-structure interaction (FSI) method for the simulation of the motion of elastic structure under the unsteady aerodynamic load induced by its motion was developed. For a given motion of the structure, the unsteady aerodynamic load of incompressible fluid was solved by immersed boundary (IB) method without the influence of elastic deformation for fluid being considered. The transient dynamic simulation of the thin-walled elastic structure was done. For a fairing separation in the ground test state, by comparing the deformation of fairing in different cases: rigid, flexible structure with or without surface loading, the feasibility of the FSI method is verified.
