This paper presents the development of an efficient implicit upwind multi-domain block-structured solver for aeroelastic computations of unsteady turbulent transonic flows around airfoils in arbitrary motion. The resolution of the structural system resolution is performed with an unconditionnally stable algorithm. Computations of two test cases with forced oscillation and one with flutter are analyzed.
