TURBINE BLADE

摘要

A turbine blade includes a first cooling air duct and a second cooling air duct which is separated from the first cooling air duct by a wall and which has a main direction, wherein the first and the second cooling-air duct are connected to one another by a first opening in the wall, wherein the wall has a second opening, to permit an improved cooling air action and thus higher operating temperatures and higher efficiency of the turbine. The second opening is adjoined by a diverting duct, the main direction of which, in the region in which the diverting duct issues into the second cooling air duct, is oriented substantially parallel to the main direction of the second cooling air duct.

1. A turbine blade comprising:
a first cooling air duct and a second cooling air duct, which is separated from the first cooling air duct by a wall, is neighboring the first cooling air duct and has a main direction, wherein the first and second cooling air ducts are connected to one another at their respective end by a first opening in the wall, wherein the wall has a second opening, which separates the wall in a middle region into a first part and a second part, wherein the second opening is adjoined by a diverting duct, the main direction of which in the region in which it enters the second cooling air duct is aligned substantially parallel to the main direction of the second cooling air duct.
