The invention belongs to the technical field of rotary flutter related test research of turboprop aircrafts, and particularly relates to a rotary flutter simulation device of a turboprop aircraft, which can simulate the rotation and gyroscopic effect of a propeller, and can research the change of yaw and pitching stiffness of an engine system, the change of a pivot point and the influence of a forward ratio on rotary flutter. The variable parameter research of the rotating speed of the fixed propeller can be realized, the variable parameter research of the state of the unpowered windmill of the propeller is considered, multiple key variable parameter researches can be realized, and the model processing and test cost can be greatly saved.
