The invention discloses a steady state and dynamic component ratio-adjustable total pressure distortion generating device and method. The device comprises a steady-state total pressure distortion generator and a dynamic sate total pressure distortion generator which are sequentially installed in the inlet pipeline of an aerodynamic stability experiment along the flowing direction of airflow; the steady state total pressure distortion generator comprises a first bracket and a wire mesh, wherein the wire mesh is detachably mounted on the bracket; and the dynamic sate total pressure distortion generator comprises a second bracket, loudspeakers, and a junction box; a plurality of loudspeakers are adopted and are fixed on the second bracket; and the wires of the loudspeakers are led out to thejunction box. The steady state and dynamic component ratio-adjustable total pressure distortion generating device and method of the present invention are capable of generating single steady state or dynamic state total pressure distortion, and are also capable of generating steady state and dynamic state combined total pressure distortion; and the ratio of steady state components to dynamic statecomponents is adjustable.
