Document Type and Number:
WIPO Patent Application WO/2017/056997
Kind Code:
A1
Abstract:
This moving blade is provided with a blade body (2) in which a cooling flow passage (10) through which a cooling medium flows is formed. The blade body (2) includes: a top plate (4) forming an apex portion; and a thinning (6) which projects from the top plate (4), on the dorsal side of a camber line (C) of a top surface (41) which faces toward the other side in the height direction Z of the blade, the thinning (6) extending along the camber line (C). A top plate flow passage (5) through which the cooling medium flows is formed inside the top plate (4). The top plate flow passage (5) includes: an inlet flow passage (51) which is formed on the dorsal side of the camber line (C) and into which the cooling medium flows; a main flow passage (52) which extends along the top plate (41) in a direction intersecting the camber line (C); and an outlet flow passage (53) which discharges the cooling medium to the outside of the blade body (2) on the ventral side of the camber line (C).
