    摘要: It provides a method for managing the remaining life of a high temperature component used in a gas turbine that enables a state of fatigue of a high temperature component to be evaluated and controlled with a high level of accuracy, and a program medium for performing the method for managing the remaining life of a high temperature gas turbine component on a computer. In the method for managing the lifespan of a high temperature component used in a gas turbine, the lifespan of a high temperature component being evaluated is set within an operating area bounded by a component life limit line that is determined on the basis of field data giving the correlation between the operating time and operating cycles for the state of fatigue from past high temperature components. As the program medium, a medium is employed that is provided with a program in which this method is used for managing a lifespan of a high temperature component used in a gas turbine.

    摘要: A collision plate having plural small holes is provided at an interval from a bottom surface of an inner shroud to form a chamber and guides cooling air from the small holes into the chamber. A leading edge flow path is provided at a leading edge side along a width direction and introduces the cooling air. A side flow path is provided along both sides of the inner shroud and guides the cooling air to a trailing edge side. A header is formed along the width direction near the trailing edge and guides the cooling air from the side flow path. Plural trailing edge flow paths are formed at the trailing edge side at intervals along a width direction, in which one end of each flow path is connected to the header and the other end is open at the trailing edge, and the cooling air in the header is ejected from the trailing edge.

    摘要: A turbine blade applicable to a gas turbine has a turbine blade body having film cooling holes, the interior space of which is partitioned into two cavities by a rib. Hollow inserts each having impingement holes are respectively arranged in the cavities to form cooling spaces therebetween. Communication is ensured between the cavities by a communication means, so that the impingement cooling is interrupted with respect to the prescribed side having a good heat transmission in the turbine blade body. A partition wall is further arranged between the rib and the insert arranged in the trailing-edge side, thus providing a separation between the cooling spaces respectively arranged in the rear side and front side. Thus, it is possible to noticeably reduce the amount of cooling air in the turbine blade body; and it is possible to reduce temperature differences entirely over the turbine blade body as small as possible.
