Abstract

PURPOSE:To improve the cooling effect by allowing the sectional area of a duct formed from a plurality of ribs formed on the inner wall surface of an outer shell and an insertion body to be different at the top edge part and rear edge part, in the constitution in which a hollow insertion body is inserted into the hollow blade-shaped outer shell. CONSTITUTION:The outer shell 1 having a hollow curved blade shape consists of a plurality of ribs 5 formed along the blade chord on the inner wall surface, and each rib 5 has a stage part 6 formed from the top edge to the intermediate part of the rear edge part. A necessary turbin blade 10 is formed by inserting a hollow insertion body 30 having the sectional shape similar to the outer shell 1 into the outer shell 1, and in this case, a duct 40 is formed by attaching the outer wall of the insertion body 30 onto the rib 5 of the outer shell 1. The groove width of a groove 7 formed by each rib 5 is increased gradually to form each rib 5, and the sectional area of the duct 40 is gradually increased towards the rear edge part against the top edge part.
