The invention provides a rigid-elastic coupling flutter wind tunnel test device. The rigid-elastic coupling flutter wind tunnel test device comprises a support member installed on a wind tunnel floor; comprising elastic wings and a wing surface connecting piece, the elastic wings are distributed on the two sides of the wing surface connecting piece, and the wing frame is supported through a supporting piece; the support is installed on the wing frame, an electric steering engine is installed on the support, a rigid winglet is installed on the support, the output end of the electric steering engine is connected with the rigid winglet, the rigid winglet is controlled to rotate through the electric steering engine, and the influence of a stability augmentation control law on rigid-elastic coupling is verified by increasing the stability augmentation control law. The test device provided by the invention can change the elastic frequency of the wing, can change the pitching inertia so as to change the rigid frequency, can also change the aerodynamic focus of the whole model, and finally verifies the influence of the control law on rigid-elastic coupling by adding the stability augmentation control law.
