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. |
