The invention discloses a long straight wing dynamics coupling wind tunnel test model with a resistance rudder, belongs to the technical field of tailless aircraft aeroelasticity wind tunnel models, and relates to a high aspect ratio wing dynamics coupling characteristic wind tunnel test model with a cracking type resistance rudder. The model comprises a basic model, a wing rigidity adjusting device, a control surface control rigidity adjusting device and a control surface deflection angle control device. Because the change of the rigidity distribution of the tailless aircraft wing can cause the change of the inherent frequency, the vibration characteristic of the tailless aircraft wing is influenced; change of control stiffness of the resistance rudder can be used for changing vibration characteristics of the control surface, and change of deflection angle of the control surface can be used for changing strength of attached vortexes. Therefore, the device provided by the invention canbe used for researching the dynamic coupling characteristic of the high aspect ratio wing with the cracking type resistance rudder.
