2.0m×1.5m Aeronautic Acoustics Wind Tunnel (FL-52)

FL-52 is constructed according to the standard of acoustics wind tunnel targeting to research test coving aerodynamic noise mechanism of aircraft, innovative noise suppression method, noise computing technology validation etc.

Main Performance:

Test section size：2.0 m×1.5m, interchangeable open/closed test sections

Max velocity：110m/s (closed), 100m/s (open)

Background noise in the test section: 80dBA (80m/s-open)

Net space of anechoic chamber: 12.5m (length)×13m (width)×9.05m (height)

Free field low frequency of anechoic chamber: 80Hz

Capability:

Aerodynamic noise research test abilities for real or scaled models of components like airfoil, landing gear, high lift device, atmospheric sensor and so on.
