Abstract (en)
The stator has a metallic sealing ring support (11) connecting a sealing ring (13) to a high pressure turbine casing (9). The support has a thermal screen element that is arranged at side of a high pressure turbine. The support is fixed to the casing by a radial transversal clamping plate (11c). The element has metallic sheets (21, 22) that arrange space (21a) with surface of the support, where the space i.e. dead cavity, is made of thermally insulating material, and the support is in form of tapered metallic warp e.g. annular ferrule.
Abstract (fr)
La présente invention porte sur un stator de turbine de moteur à turbine à gaz comprenant un carter (9) de turbine, un anneau (13) d'étanchéité de turbine et un support d'anneau d'étanchéité (11) reliant l'anneau (13) d'étanchéité au carter (9). Le stator est caractérisé par le fait que le support (11) est pourvu d'un élément formant écran thermique disposé du côté de la turbine. Cette solution permet de réduire les consommations de jeu pendant les phases de fonctionnement transitoires.
