Keywords: delta wing, store flutter, store aerodynamics, CFD, transonic flow

Influence of the store aerodynamics on the transonic flutter of a simple delta wing is examined using the fluid/structure coupling method. It is found that the locations of the shock wave on the lower surface of the wing would be the key factor for the flutter instabilites.
