FIELD: non-displacement compressors and pumps.
SUBSTANCE: invention relates to gas turbines. Gas turbine housing (100) is made from an organic-matrix composite material comprising a reinforcement densified by an organic matrix and delimits an inner volume. Housing comprises, on inner surface (101) a structural element (120) having first surface (120a) facing the inner surface of the housing and second opposing surface (120b) defining flow channel portion (102). First surface of the structural element includes grooves that open directly or indirectly into the interior of the housing, said grooves extending at least in the axial direction of the housing.
EFFECT: technical result is providing, during a fire, the release of gas resulting from the decomposition of the resin of the housing into the flow channel.
