AXIAL FLOW TURBINE STRUCTURE

摘要

In the manufacturing of stator vanes for the first stage of a multi-stage axial flow gas turbine, casting difficulty and casting cost are reduced by making a separate casting for each vane instead of making segmental groups of vanes which are costly due to a high casting rejection rate. The vanes are supported by grooved holding blocks attached to the blade ring of the turbine, and they are readily assembled or removed. An improved cooling system is provided for the vanes which are of a hollow construction.
