This paper presents a framework of rigid&elastic coupling stability analysis of the hypersonic vehicles with complex configurations. Local piston theory based on CFD methods is introduced into the flight dynamic analysis process to take 3D effect into consideration. The flight dynamic equations considering elasticity are established in the coordinates of mean axes. Through the eigenvalue analysis of the state space equations, the longitudinal stability is discussed. And the influence of structural stiffness is discussed as well.
