Abstract

L'invention concerne un dispositif réfrigérant pour aubes de guidage de moteur à turbine à gaz prévoyant une réfrigération séparée pour certaines parties des aubes travaillant sous haute température, telles que la zone de fuite des plateaux de la couronne d'aubes. Le dispositif comprend une plaque 22 fixée à la bride de montage 20 du plateau 19 et s'étendant parallèlement et à distance de la face non touchée par les gaz de la zone de fuite de ce plateau de façon à creer un espace 25 occupé par des colonnettes de liaison 23, génératrices de turbulence et conductrices de chaleur, et alimenté, par des ouvertures 26 traversant la bride 20, en air réfrigérant s'échappant par le bord de fuite du dispositif selon un angle voisin du sens d'écoulement du courant gazeux principal.The invention relates to a refrigeration device for guide vanes of a gas turbine engine providing separate refrigeration for certain parts of the vanes operating at high temperature, such as the leakage zone of the vane crown plates. The device comprises a plate 22 fixed to the mounting flange 20 of the plate 19 and extending parallel to and away from the non-gas-touched face of the leakage zone of this plate so as to create a space 25 occupied by connecting columns 23, generating turbulence and conducting heat, and supplied, by openings 26 passing through the flange 20, with refrigerant air escaping through the trailing edge of the device at an angle close to the direction of flow of the gas current main.
