Abstract

A blade for a gas turbine comprises: a blade part comprising a front edge part and a rear edge part and having a streamlined cross section; a supporting part comprising inlets in which compressed air flows from the outside and supporting one end of the blade part; and a plurality of serpentine channels of which one end is connected with each inlet and which extend in parallel inside of the blade part so as to enable the compressed air received through each inlet to pass therethrough.
