Abstract

TITRE : Carter pour turbomachine et turbomachine équipée d’un tel carter Un aspect de l’invention concerne un carter (100) pour une turbine de turbomachine, le carter s’étendant autour d’un axe et comprenant une paroi annulaire (101) ainsi qu’au moins un élément d’accroche (110) qui s’étend en saillie à partir d’une surface radialement interne (102) de la paroi annulaire du carter et qui est formé, au moins en partie, d’un premier matériau. Ledit élément d’accroche est pourvu d’au moins un insert (120) qui s’étend de l’élément de l’élément d’accroche jusqu’à une surface radialement externe (103) de ladite paroi annulaire pour déboucher du côté externe du carter, l’insert étant formé dans un deuxième matériau ayant une diffusivité thermique supérieure à la diffusivité thermique du premier matériau. L’invention concerne également un ensemble pour turbine et une turbomachine comprenant un tel carter. Figure à publier avec l’abrégé : Figure 3TITLE: Housing for a turbomachine and turbomachine equipped with such a housing One aspect of the invention relates to a housing (100) for a turbomachine turbine, the housing extending around an axis and comprising an annular wall (101) thus that at least one gripping element (110) which projects from a radially internal surface (102) of the annular wall of the housing and which is formed, at least in part, of a first material . Said hooking element is provided with at least one insert (120) which extends from the element of the hooking element to a radially outer surface (103) of said annular wall to open out on the outer side of the housing, the insert being formed from a second material having a thermal diffusivity greater than the thermal diffusivity of the first material. The invention also relates to an assembly for a turbine and a turbomachine comprising such a casing. Figure to be published with the abstract: Figure 3
