| Abstract: | The.0.6m×0.6m supersonic wind tunnel is a direct current temporary rush wind tunnel,the wind tunnel running will produce 120dB noise.In order to reduce the rocket noise influence,the paper puts forward frondose noise reduction measures,bases on measure data and the theoretic analysis.The results will provide the reference for the design of the wind tunnel workshop’s build. |
