- •
The design criteria and layout of an aeroacoustic wind tunnel is described in this paper.
- •
Some critical design treatments are used to improve both aerodynamic and acoustic performance. The background noise is comparable with other acoustic facilities and the turbulence intensity in the core of test section is less than 0.08%.
- •
Noise radiated from test model is adequately higher than the background noise for a wide range of frequency.
