Abstract
Carter de turbine de moteur à réaction avec un anneau en matériau poreux abradable. Dispositif support et de montage constituant une structure cylindro-conique monobloc comportant une chemise intérieure conique permettant le refroidissement par convection de la surface extérieure et une chemise cylindrique distribuant l'air de refroidissement à l'anneau abradable par l'intermédiaire d'une virole perforée solidaire du reste du dispositif. L'anneau abradable porte des cloisons transversales pour éviter les fuites axiales. Application aux carters de turbine avec anneau en matériau fritte poreux.
