Noise protection enclosures for helicopter test stands

The noise enclosure is equipped with an extensive, horizontal intake silencer for cooling-air. The exhaust air silencer is mounted flat on the roof of the enclosure. The sides of the enclosure are constructed of detachable wall elements to facilitate the mounting of the engines being tested. The design and the drawing are made by LBF – of course, always incorporating the customer’s wishes, e.g. with regard to openings, lighting and observation windows.
