The invention relates to the technical field of steering engine testing, and discloses a device for testing the deflection angle of an aircraft steering engine, the device comprises a shell, a wing plate, a first rack and a second rack, one side of the shell is provided with an air outlet, the wing plate is vertically arranged in the air outlet, the other side of the shell is fixedly provided with a main air pipe, and the upper end of the shell is fixedly connected with a mounting frame; the mounting frame is connected with a measuring mechanism, the measuring mechanism is used for testing the change of the mechanical deflection angle of the steering engine when the wing plate is subjected to wind and can test the influence of a mechanical gap on the mechanical deflection angle of the steering engine under the windless condition, and a turbulent flow mechanism is arranged in the shell and is used for providing crosswind to act on the two sides of the wing plate during testing. The device for testing the deflection angle of the aircraft steering engine can simulate various working conditions in different wind directions, test the control capability of the steering engine on the mechanical deflection angle under the complex airflow condition, and in addition, can quickly test the influence quantity of a gap existing in a steering engine transmission mechanism on the mechanical deflection angle.
