Kind Code:
A1
Abstract:
This cooling structure for a turbine blade (1) is provided with: a cooling passage (17) formed between a first blade wall (3) that is curved in a concave shape with respect to a high-temperature gas flow passage (GP) and a second blade wall (5) that is curved in a convex shape; and a lattice structure (23) formed by superposing, in a lattice shape, a plurality of main ribs (31A, 31B) provided on both wall surfaces facing the cooling passage, wherein the lattice structure (23) has sub ribs (37A, 37B) which are integrally formed on the main ribs (31A, 31B) so as to protrude into a lattice flow passage (35) formed between the main ribs adjacent to each other, and the sub rib (37A) disposed on the inner wall surface of the first blade wall and the sub rib (37B) disposed on the inner wall surface of the second blade wall are provided at positions which do not overlap each other.
