Title

GAS TURBINE ENGINE COMPONENT WITH IMPINGEMENT AND DIFFUSIVE COOLING
(FR)
COMPOSANT DE MOTEUR À TURBINE À GAZ COMPORTANT UN REFROIDISSEMENT PAR CONTACT ET DIFFUSION
Abstract:
(EN)
A gas turbine engine component includes a gas path wall having a first surface and second surface and an impingement baffle having impingement holes for directing cooling fluid onto the first surface of the gas path wall. A cooling hole extends through the gas path wall. The cooling hole continuously diverges from an inlet in the first surface to an outlet in the second surface such that cross-sectional area of the cooling hole increases continuously from the inlet to the outlet. A longitudinal ridge divides the cooling hole into lobes.
(FR)
L'invention porte sur un composant de moteur à turbine à gaz comprenant une paroi de trajet de gaz, ayant une première surface et une seconde surface, et un déflecteur de contact ayant des trous de contact pour diriger un fluide de refroidissement sur la première surface de la paroi de trajet de gaz. Un trou de refroidissement s'étend à travers la paroi de trajet de gaz. Le trou de refroidissement diverge de façon continue d'une entrée dans la première surface à une sortie dans la seconde surface de telle sorte que l'aire de section transversale du trou de refroidissement croît de façon continue de l'entrée à la sortie. Une crête longitudinale divise le trou de refroidissement en lobes.
