<P>PROBLEM TO BE SOLVED: To provide a cooling structure of a high temperature member which improves efficiency of cooling the entire high temperature member. <P>SOLUTION: The cooling structure of a platform 12 of a rotor vane 1 cools the platform 12 by flowing cooling air W inside the platform 12. The cooling structure includes a main cooling hole 32 of which one end part 23 is opened to an outer surface of the platform 12 and the other end part 24 is communicated with a supply source of the cooling air W, a blocking member 35 blocking the opening of the main cooling hole 32 at the outer surface of the platform 12, branched cooling holes 33 formed of smaller diameters than the main cooling hole 32 and branched from the main cooling hole 32, and an end part stagnation preventing hole 34 communicated with the end part 23 of the main cooling hole 32 and for introducing the cooling air W to the outside of the platform 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
