Cooled Working Blade of a Gas Turbine.

摘要

A cooled working blade of a gas turbine with a root, for example of the fir-tree type, in which an aperture is made for supply of cooling air, is distinguished by the fact that for the purpose of decreasing the leakage of cooling air, continuous projections are made with transverse slots on the edges of the root end for a footing which fixes the blade in an axial direction.
