PROBLEM TO BE SOLVED: To solve the problem of requiring an improved system for cooling a turbine moving blade tip shroud so that a metal temperature caused by a high temperature turbine environment drops. SOLUTION: A turbine moving blade 10 includes a tip shroud 20, one or more of cooling cavities 130 formed in the tip shroud 20, and at least one rib 142 and 144 formed in at least one cooling cavity 130. The ribs 142 and 144 are dimensionally determined and oriented so as to extend a part of a distance of crossing the cooling cavity 130. The ribs 142 and 144 may be dimensionally determined and oriented so as to extend to at least a great part of the distance of crossing the cooling cavity 130. The great part of the distance of crossing the cooling cavity 130, is at least 75% of the distance of crossing the cooling cavity 130. COPYRIGHT: (C)2009,JPO&INPIT |
