The open rotor has high propulsion efficiency and is an important development direction in the aero engine field. However， the aerodynamic interference of open rotor is complicated and the radiated aerodynamic noise is strong， making aerodynamic noise become a key problem in the development of open rotor engines. To evaluate the aerodynamic noise characteristics of the open rotor， verify the aerodynamic noise prediction method of the open rotor， and analyze the aerodynamic noise mechanism of the open rotor， the aerodynamic noise test of typical open rotor was carried out in the 5.5 m x 4 m acoustic wind tunnel by using a newly developed high-power open rotor dynamic simulation test device. The processing method of the wind tunnel test data of open rotor aerodynamic noise is established， the order decomposition method of open rotor aerodynamic noise is developed， and the characteristics and mechanism of open rotor aerodynamic noise are systematically studied. The results show that the separation error of different orders of tone for open rotor is less than 0.26 dB. The aerodynamic noise of open rotor is rich and obvious and covers a wide frequency range， with single frequency noise being the main noise source of open rotor. The total noise and single-frequency noise of the open rotor mainly propagate towards the radiation angle of 90o， the wide frequency noise mainly propagates towards the rear of the propeller plane， and the single tone of front propeller and rear propeller mainly propagate towards the radiation angle of 70°–110°.
