Title
(EN) COMPARTMENTALIZATION OF COOLING FLOW IN A STRUCTURE COMPRISING A CMC COMPONENT
(FR) COMPARTIMENTATION D'UN FLUX DE REFROIDISSEMENT DANS UNE STRUCTURE COMPRENANT UN COMPOSANT CMC
Abstract
(EN)
A structure in a gas turbine engine comprises a spar and a CMC component adjoining the spar and separated from the spar by a cavity supplied by cooling air. At least one rope seal is installed in the cavity within a groove made in the spar to thus compartmentalize the cavity and control the flow of cooling air.
(FR)
La présente invention concerne une structure de moteur de turbine à gaz comprenant un longeron et un composant CMC contigu au longeron et séparé de ce dernier par une cavité alimentée en air de refroidissement. Au moins un cordon d'étanchéité est installé dans la cavité à l'intérieur d'une rainure réalisée dans le longeron pour ainsi compartimenter la cavité et commander le flux d'air de refroidissement.
