Analysis of Supersonic Thermo-Flutter of the Wing with High Angle of Attack

The thermo-flutter of supersonic wing with high angle of attack under the condition of aerodynamic heating was analyzed in this paper.The flutter motion equation was founded by modal superposition method.The unsteady aerodynamic forces in the supersonic and subsonic field were calculated respectively by the methods of local flow piston theory and the linearization theory of small disturbance.And the motion response was solved by state space method and Runge-Kutta method.The computation results of the two examples showed that the accuracy of the method met the requirement in engineering.Meanwhile,the impact of aerodynamics heating on flutter was discussed.
