Title (EN) SUPPLY SYSTEM OF GAS TURBINE COMPONENT COOLING
(FR) SYSTÈME D'ALIMENTATION EN REFROIDISSEMENT DE COMPOSANT DE TURBINE À GAZ
Abstract:
(EN) The present invention provides a supply system (7) for gas turbine component cooling, wherein the gas turbine component is a hollow component (1) that is required to be cooled, for example a gas turbine blade, a gas turbine vane, a gas turbine strut, etc. The supply system (7) comprises at least one orifice (5) for supplying cooling agent into the gas turbine component and arranged at an end wall (2) of the gas turbine component. In addition to that the supply system (7) comprises at least one bimetallic component (8) arranged in the area of the at least one orifice (5). Furthermore the at least one bimetallic component (8) is adapted to open and close the at least one ' orifice depending on the temperature of the gas turbine component (1).
(FR) La présente invention concerne un système d'alimentation (7) pour refroidissement de composant de turbine à gaz, le composant de turbine à gaz étant un composant creux (1) qui doit être refroidi, par exemple une pale de turbine à gaz, une aube de turbine à gaz, une entretoise de turbine à gaz, etc. Le système d'alimentation (7) comprend au moins un orifice (5) pour apporter un agent de refroidissement dans le composant de turbine à gaz et agencé au niveau d'une paroi d'extrémité (2) du composant de turbine à gaz. En plus de cela, le système d'alimentation (7) comprend au moins un composant bimétallique (8) disposé dans la zone du ou des orifices (5). En outre, le ou les composants bimétalliques (8) sont conçus pour ouvrir et fermer le ou les orifices en fonction de la température du composant de turbine à gaz (1).
