Abstract
Official abstract text for this publication.
In a structure for internally cooling a turbine blade, a cooling medium passage is provided in the turbine blade. The cooling medium passage has a shape in which a plurality of cylindrical spaces, each having substantially cylindrical shape, extending in parallel with each other partially overlap each other. A cooling medium supply passage that supplies a cooling medium to the cooling medium passage is connected to a portion of the cooling medium passage that includes a peripheral wall, in a direction that forms an acute angle with respect to a longitudinal direction of the cooling medium passage.
First claim
Opening claim text (preview).
What is claimed is: 1. A turbine blade cooling structure for internally cooling a turbine blade, comprising: a cooling medium passage provided in the turbine blade and having a shape in which a plurality of cylindrical spaces, each having a substantially cylindrical shape, extending in parallel with each other partially overlap each other; and a cooling medium supply passage to supply a cooling medium to the cooling medium passage connected to a portion of the cooling medium passage that includes a peripheral wall, said cooling medium passage forms an acute angle with respect to a longitudinal direction of the cooling medium passage. 2. The turbine blade cooling structure as claimed in claim 1 , wherein the two cylindrical spaces adjacent to each other overlap each other such that an overlap length W along a straight line connecting centers of cross-sectional circles of the adjacent two cylindrical spaces satisfies a relationship of 0.05≤W/((D 1 +D 2 )/2)≤0.35 with respect to a cross-sectional diameter D 1 of one of the cylindrical spaces and a cross-sectional diameter D 2 of the other cylindrical space. 3. The turbine blade cooling structure as claimed in claim 1 , wherein the cooling medium supply passage is connected to an overlapped region of the adjacent two cylindrical spaces of the cooling medium passage. 4. The turbine blade cooling structure as claimed in claim 3 , wherein the cooling medium supply passage is connected to the overlapped region such that the cooling medium supplied from the cooling medium supply passage collides against a partition edge formed between the adjacent two cylindrical spaces. 5. The turbine blade cooling structure as claimed in claim 1 , wherein the cooling medium supply passage is connected to a side portion of the cooling medium passage, the side portion being located at a side opposite to the overlapped region of the cylindrical spaces, on a straight line connecting centers of cross-sectional circles of the adjacent two cylindrical spaces of the cooling medium passage.
