The invention at hand relates to a housing for a compressor of a gas turbine, in particular of an aircraft gas turbine, with an external housing (12) with at least one air supply opening (14) and an interior housing (18) formed by at least two housing segments (16), with the housing segments (16) having at least one injection nozzle (20) to inject air suctioned in via the air supply openings (14) into a flow channel (22) in the area of blade tips (26) of blades (24) of a rotor (28) of the compressor. In this case, the housing segment (16) has at least one air flow channel (30), with the air flow channel (30) being designed in such a way that a direct air supply to the at least one injection nozzle (20) occurs via at least one air supply element (32) arranged in the air supply opening (14) of the exterior housing (12). The invention relates moreover to a compressor of a gas turbine as well as to a method for the manufacture of a housing segment (16) of a compressor housing (10).
L'invention concerne un carter de compresseur de turbine à gaz, notamment de turbine d'avion, comportant un carter externe (12) pourvu d'au moins une ouverture d'entrée d'air (14) et un carter interne (18) formé d'au moins deux segments (16), ces segments de carter (16) comportant au moins une buse d'insufflation (20) destinée à insuffler l'air aspiré par les ouvertures d'entrée d'air (14) dans un canal d'écoulement (22) dans la zone des têtes (26) des aubes (24) d'un rotor (28) du compresseur. Le segment de carter (16) comporte au moins un canal de guidage d'air (30) conçu de manière que l'air soit guidé directement vers la ou les buses d'insufflation (20) par au moins un élément d'entrée d'air (32) disposé dans l'ouverture d'entrée d'air (14) du carter externe (12). L'invention porte également sur un compresseur de turbine à gaz et sur un procédé de fabrication d'un segment (16) de carter de compresseur (10).
