Title (EN) GAS TURBINE ENGINE SHAPED FILM COOLING HOLE
(FR) TROU DE REFROIDISSEMENT DE FILM FORMÉ DE TURBINE À GAZ
Abstract:
(EN) A component for a gas turbine engine includes a wall that adjoins an interior cooling passage and provides an exterior surface. A film cooling hole fluidly connects the interior cooling passage and the exterior surface. The film cooling passage includes inlet and outlet passages that fluidly interconnect and adjoin one another in a misaligned non-line of sight relationship.
(FR) La présente invention se rapporte à un composant d'une turbine à gaz, ledit composant comprenant une paroi qui est contiguë à un passage de refroidissement intérieur et comporte une surface extérieure. Un trou de refroidissement de film relie fluidiquement le passage de refroidissement intérieur et la surface extérieure. Le passage de refroidissement de film comprend des passages d'entrée et de sortie qui communiquent de façon fluidique les uns avec les autres, et sont contigus les uns aux autres, selon une relation de visibilité non directe mal alignée.
