Title
(EN) TURBINE BLADE WITH A COUPLED SERPENTINE CHANNEL
(FR) AUBE DE TURBINE À CANAL EN SERPENTIN COUPLÉ
Abstract
(EN)
A turbine blade (440) having a base and an airfoil (441), the base including a root end (444). The airfoil including a skin (460) extending from the base and defining a first edge (446, 447), a second edge (446, 447), having a tip end (445) opposite from the root end. The turbine blade further including a base rib (490a, 490b) extending from the base and into the airfoil, a center divider (492a, 492b) extending from adjacent the first edge towards the second edge, a center rib (493a, 493b) disposed between the center divider and the second edge, extending from adjacent the center divider towards the tip end and extending from adjacent the center divider towards the root end, a tip center rib (498a, 498b) extending from adjacent the second edge towards the first edge, a tip rib (496a, 496b) extending from adjacent the tip center rib towards the base, a dividing rib (480a, 480b) and a first channel (474a, 474b).
(FR)
Aube (440) de turbine présentant une base et un profil aérodynamique (441), la base comprenant un pied (444). Le profil aérodynamique comprend une peau (460) s'étendant à partir de la base et définissant un premier bord (446 447), un second bord (446 447), présentant une extrémité (445) opposée au pied. L'aube de turbine comprend également une nervure de base (490a,490b) s'étendant à partir de la base et jusque dans le profil aérodynamique, un diviseur central (492a, 492b) s'étendant depuis la zone adjacente au premier bord vers le second bord, une nervure centrale (493a, 493b) disposée entre le diviseur central et le second bord, s'étendant à partir de la zone adjacente au diviseur central vers l'extrémité et s'étendant depuis la zone adjacente au diviseur central vers le pied, une nervure centrale de d'extrémité (498a, 498b) s'étendant depuis la zone adjacente au second bord vers le premier bord, une nervure d'extrémité (496a, 496b) s'étendant à partir de la zone adjacente à la nervure centrale d'extrémité vers la base, une nervure de division (480a,480b) et un premier canal (474a, 474b).
