Title (EN) TURBOMACHINE CENTRIFUGAL BREATHER COMPONENT AND METHOD FOR MANUFACTURING SAID COMPONENT
(FR) PIECE POUR DEGAZEUR CENTRIFUGE DE TURBOMACHINE ET PROCEDE DE FABRICATION DE LADITE PIECE
Abstract:
(EN) The invention relates to a component for a centrifugal breather for removing gas from a turbomachine air/oil mixture, which component is intended to rotate about an axis of symmetry (X), comprising a structural part (2, 3) configured to delimit a flow path (4) for the flow of said mixture comprising: a circumferential chamber (10) for the centrifugal separation of said mixture; an axial inlet (6) for said air/oil mixture into said chamber (10); radial oil outlets (9), an outlet (16) for oil-free air, further comprising at least one cellular structure (5) made for example from a material of the metallic foam type, configured to filter the oil while allowing the air to pass and occupying at least a space (17) in said flow path (4) which closes the communication between the axial inlet (6) and the internal radial outlet (12), characterized in that the structural part (2, 3) and the cellular structure (5) are formed as a single component. The invention also relates to a method for the additive manufacture of said component.
(FR) L'invention concerne une pièce pour un dégazeur centrifuge d'un mélange air/huile de turbomachine, destinée à tourner autour d'un axe de symétrie (X), comprenant une partie structurelle (2, 3) configurée pour délimiter une veine (4) pour le flux dudit mélange comportant: une enceinte (10) circonférentielle de séparation centrifuge dudit mélange; une entrée axiale (6) dudit mélange air/huile dans ladite enceinte (10); des sorties radiales (9) d'huile, une sortie d'air déshuilé (16), comprenant en outre au moins une structure alvéolaire (5), composée par exemple d'un matériau de type mousse métallique, configurée pour filtrer l'huile en laissant passer l'air et occupant au moins un espace (17) dans ladite veine (4) qui ferme la communication entre l'entrée axiale (6) et la sortie radiale interne (12), caractérisée en ce que la partie structurelle (2,3) et la structure alvéolaire (5) sont formées d'une seule pièce. L'invention concerne également un procédé de fabrication additive de ladite pièce.
