An unsteady aerostructure coupled adjoint method is presented for computing shape sensitivities of unsteady flows with fluid–structure interactions. The nominal flow solver is an unsteady Euler solver based on a stationary Cartesian grid using transpiration boundary conditions. With Hilbert transformation, a novel damping-related cost function is defined for which the shape sensitivity can be computed by the new unsteady aerostructure coupled adjoint method. The capability of the new method is demonstrated by a successful airfoil shape optimization for flutter suppression.
