Abstract
A gas turbine blade includes a plurality of guide ribs spaced apart from each other in a movement direction of a cooling fluid in order to guide movement of the cooling fluid flowing along a cooling passage formed in the turbine blade, and an opening formed in each of the guide ribs in order to guide a portion of the cooling fluid to a bottom of the cooling passage between the guide ribs or to side walls adjacent to the bottom.
Claims17
A gas turbine blade, comprising:
- a plurality of guide ribs spaced apart from each other in a movement direction of a cooling fluid that guide movement of the cooling fluid flowing along a cooling passage formed in the turbine blade;
- and
- an opening defined in each of the guide ribs that guides a portion of the cooling fluid to a lower portion of the cooling passage between the guide ribs or to side walls adjacent to the lower portion.
A gas turbine blade comprising:
- a plurality of guide ribs spaced apart from each other in a movement direction of a cooling fluid that guide movement of the cooling fluid flowing along a cooling passage formed in the turbine blade, each guide rib including an inclined portion configured such that a front, upper surface in a width direction of the guide rib that comes into contact with the cooling fluid is inclined downwardly toward a lower portion of the cooling passage;
- and
- an opening respectively defined in the front surface of each of the guide ribs such that a portion of the cooling fluid is supplied to the lower portion of the cooling passage between the guide ribs or to a first heat conduction region in which heat transfer is relatively lowered in side walls adjacent to the lower portion.
