FIELD: power engineering.
SUBSTANCE: invention relates to turbounits of gas-transfer set and gas-turbine power stations. Proposed noise-absorbing shell of gas-turbine plant has load-bearing skeleton, outer housing and inner panels with noise absorbing material placed in between. Upper cover of housing is made detachable. For this purpose edges of cover form flange with holes on which longitudinal elements are installed at angle forming faces of truncated pyramid, and inner panel is secured on smaller base of pyramid. Guides with surfaces are made on mating part of skeleton equidistant to faces of truncated pyramid. Elastic gasket is arranged between flange and skeleton, and flange is fastened on skeleton, for instance, by means of screws.
EFFECT: improved operating characteristics of shell owing to possibility of taking out engine from top of shell.
