The wind tunnel laboratory ( construction area of 4665m² ) has a boundary layer wind tunnel with down-blowing double-spectrum, which is the largest in construction scale in China. The total length of the wind tunnel is 96.5 meters. Its high speed spectrum is 4m×3m×22m( width×height×length ) with the highest wind speed of 30m/s, and its low speed spectrum is 6m×3.5m×21m with the highest wind speed of 18m/s. With such advanced testing equipments as synchronous electronic scanning valve, multiple laser vibration meter and high-frequency scale, the laboratory can carry out research and consultation work on anti-wind and wind environment experiment, CFD numerical simulation, and wind vibration analysis.
