TURBO-ENGINE COMPONENT

摘要

Disclosed is a turbo-engine component comprising a wall, the wall comprising a hot gas side surface and a coolant side surface. At least one coolant discharge duct is provided in said wall and opening out onto the hot gas side surface at a coolant discharge opening. A coolant flow direction is defined from the interior of the coolant discharge duct towards the discharge opening, the coolant discharge duct further being delimited by a delimiting surface thereof provided inside the wall. The coolant discharge duct has a first cross sectional direction and a second cross sectional direction. The coolant discharge duct is a blind cavity and is closed towards the coolant side surface, and further a dimension of the coolant discharge duct measured in the first cross sectional direction decreases in the coolant flow direction.
