TURBINE BLADE, IN PARTICULAR FOR A GAS TURBINE ENGINE

원문 (중국어)

A turbine blade, having an airfoil and, in an installed state, extending radially with an axial inclination from a leading edge to a trailing edge, and in which a cooling channel is formed. The cooling channel has a leading channel portion, which extends at least predominantly radially, close to the leading edge, a trailing channel portion, which extends at least predominantly radially, close to the trailing edge, and an inner channel portion, situated between these and oriented at least predominantly radially, as well as a first and second deflecting portion, which connect these channel portions. In relation to a cooling fluid passed through the cooling channel arrangement during cooling operation, the leading channel portion or the trailing channel portion forms the inlet-side channel portion. Efficient cooling is brought about by the inner channel portion being arranged downstream of the leading channel portion and of the trailing channel portion.
