  • According to the acoustic experimental conducted in the 0. 6m continuous transonic wind tunnel of CARDC(China Aerodynamics Research and DevelopmentCenter), the noise generation process in test section and the propagation process in tunnel circuit were researched. Acoustic treatments were performed on both the compressor rear cone and the fourth corner to prevent the emitted noise from propagating forward. Meanwhile the wind tunnel was running with second throat throttling to suppress the downstream noise. With those effective means to reduce the circuit noise, the optimization design of active noise reduction schemes with different ventilation wall types and different design parameters was carried out, then an excellent design for the test section wall was achieved. The wind tunnel pressure fluctuation coefficient reached the target of less than 0. 8%,the advanced international level.
