Abstract
(EN)
The present invention relates to a gas turbine blade comprising an outer structure, an inner structure, a plurality of porous slots and a cooling medium channel, wherein the outer structure is formed in an airfoil shape of which the inside is empty, and has a plurality of mounting grooves arranged to be spaced apart in a chord direction oriented toward a trailing edge from a leading edge, the inner structure is accommodated inside the outer structure and has a plurality of protrusion parts protruding toward the inner surface of the outer structure so as to come in close contact with the inner surface of the outer structure and be arranged to be spaced apart in the chord direction, the porous slots are detachably coupled to the mounting grooves, and are arranged on the outer structure to be spaced apart in the chord direction, and the cooling medium channel is formed such that a cooling medium flows among the porous slots, the adjacent protrusion parts and the outer surface of the inner structure.
