| Abstract: | Based on aeroacoustic characteristics of propellers which can be tested in NF-3 wind tunnel and requirements of an acoustical testing, this paper provids a construction scheme to make NF-3 wind tunnel to be an acoustical one. The results prove that the scheme is successful and NF-3 wind tunnel has the experimental ability for propeller acoustical testing. |
