An actively cooled component (24) having a plurality of film cooling discharge apertures (50) passing through a heat transfer pedestal (55). In one embodiment the pedestal (55) is elongated so as to provide good covered turning for the cooling media exiting the cooled component. In one embodiment the discharge aperture has an L/D ratio in the range of about two to three.
La présente invention concerne un composant à refroidissement actif (24) pourvu d'une pluralité d'orifices de décharge de refroidissement lamellaire (50) au travers d'un bâti-support à transfert thermique (55). Selon une réalisation, le bâti-support (55) est de forme allongée de façon à assurer un bon retour guidé du fluide de refroidissement sortant du composant refroidi. Pour l'un des modes de réalisation, le coefficient de finesse de l'orifice de décharge est de l'ordre de deux à trois environ.
