Definitions

  • a reduction in the flow rate of the cooling fluid can be achieved due to the widening deceleration area, so that the cooling fluid can contact the outer wall immediately downstream of the outlet.
  • the wall structure can also have an inner wall facing the interior, a cooling region being provided between the inner wall and the outer wall for the flow of cooling fluid.
  • Each cooling area has an inlet for cooling fluid assigned to the inner wall. This ensures that cooling fluid guided in the interior flows into the cooling area. Cooling fluid passes from the cooling area through the outlet to the outer surface of the outer wall.
  • the cooling area is preferably designed as a cooling chamber which is enclosed by the outer wall and the inner wall. This increases the flexibility in the manufacture of the inlet and outlet and also makes it possible to change the inlet and outlet of cooling fluid retrospectively in accordance with the requirements for the turbine blade.

Abstract

L'invention concerne une aube de turbine (1) comprenant une zone d'attaque (8) et une zone de fuite (9) séparées par un côté pression (10) et un côté aspiration (11) opposés. L'aube comprend également une structure à parois (2) sur laquelle s'écoule un fluide. La structure à parois (2) comporte une paroi externe (3) qui entoure un espace interne (21) destiné à guider un fluide de refroidissement (6), et une sortie (16) destinée au fluide de refroidissement (6). Une surélévation (14), située au niveau de la sortie (16), est orientée vers l'intérieur (21). L'invention concerne également l'utilisation d'une aube de turbine (1) dans une turbine à gaz.
