摘　　要：在分析螺旋桨噪声特性和声学实验对风洞的要求的基础上,结合NF-3风洞的特点和声学工程设计经验,对该风洞螺旋桨实验段进行了声学改造。检测结果表明,改造的效果令人满意,NF-3风洞已初步具备声学实验能力。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.
