NOISE PROTECTION EQUIPMENT SYSTEM FOR CENTRIFUGING HELICOPTER SPAR TUBES
The experimental results of noise and vibration in the section of the centrifugal treatment of the helicopter longeron tubes are given. Noise sources determining very high level increase over limitary spectra are identified. As the noise reduction up to the sanitary norms in the source itself is imp...
