The invention concerns a gas turbine engine axial stator compressor comprising a rigid outer annular frame (2), axially juxtaposed rings (4a, 4b, 4c), arranged inside the frame (2) and bearing fixed blade rims (5), said rings consisting of circular sectors (7) fixed to the frame (2) and whereof the inner wall externally delimits the compressed gas fluid aerodynamic duct. The invention is characterised in that the circular sectors (7) are brazed sectors consisting of a cellular structure (8) sandwiched between an inner plate (10) defining the aerodynamic conduit and an outer plate (9) and the link with the frame (2) is solely provided by the outer plate (9).
L'invention concerne un stator de compresseur axial de turbine à gaz
comportant une armature (2) annulaire externe rigide, des anneaux (4a, 4b, 4c)
axialement juxtaposés, disposés à l'intérieur de l'armature (2) et portant des
couronnes d'aubes fixes (5), ces anneaux étant constitués par des secteurs
circulaires (7) fixés à l'armature (2) et dont la paroi interne délimite
extérieurement le conduit aérodynamique du fluide gazeux comprimé, caractérisé
par le fait que les secteurs circulaires (7) sont des secteurs brasés
constitués d'un nid d'abeille (8) pris en sandwich entre une tôle intérieure
(10) délimitant le conduit aérodynamique et une tôle extérieure (9) et par le
fait que la liaison avec l'armature (2) est uniquement assurée par la tôle
extérieure (9).
