Abstract:
A gas turbine moving blade assembly comprising:a leading edge confronting a combustion gas flow and a trailing edge;a cooling passage defined in an interior of said leading edge for causing cooling air to flow from a proximal end portion of the blade to a tip end of the blade; and,a plurality of turbulators arranged in a direction transverse to a flow of the cooling air and slanted relative to the combustion gas flow, wherein said plurality of turbulators includes long turbulators and short turbulators, both said long turbulators and said short turbulators being provided on facing inner wall surfaces of the cooling passage,wherein said long turbulators and said short turbulators are slanted from the leading edge, in a direction into the flow of the cooling air, toward a downstream side of the combustion gas flow.
