      After three years of construction, a new 2.0m acoustic wind tunnel (FL-52), which is located in Harbin, China, has been put into use in November, 2018.

FL-52 wind tunnel is an aeroacoustic circuit wind tunnel with a closed-wall test section and an open jet.

 

 

Main features:

l  Test section size: 2.0m×1.5m

l  Maximum velocity: 110m/s (closed-wall test section )

100m/s (open jet section)

l  Background noise of the open jet section at 80m/s: 80dBA

l  anechoic chamber size: 12.5m (length)×13m (width)×9.05m (height)

l  Free field cutoff frequency of anechoic chamber: 80Hz

FL-52 wind tunnel is used for noise investigation of fuselage and components of aircraft, as well as automotive and high-speed train. It can meet the requirements of aeroacoustic mechanism research, noise reduction method research and wind tunnel test verification. The first test campaign has been successfully completed in November.

Apart from acoustic wind tunnel, AVIC ARI has a professional aeroacoustic team which can solve aeroacoustic issues of airplane, helicopter and aeroengine by using innovative testing techniques, computational techniques, noise reduction design techniques and software tools.
