Through the use of the corner turning vanes and screens, the quality of the flow is controlled with high accuracy.
The noise of the wind tunnel is kept low and it does not affect the results in the acoustics measurements test sessions.
Less energy is required for a given test section size and velocity: this aspect is important when completing developmental experiments with high utilization.
There is a reduced environmental noise when operating.
