Title: FLOW PATH FORMING PLATE, BLADE PROVIDED WITH SAME, GAS TURBINE PROVIDED WITH SAME, AND METHOD FOR MANUFACTURING FLOW PATH FORMING PLATE
Abstract:
A flow path forming plate has formed therein a gas path surface (64p) in contact with combustion gas, an end surface formed at the peripheral edge of the gas path surface (64p), a first side through channel (90i), and a plurality of end surface spray through channels (71). The first side through channel (90i) extends along a first end surface (62b), which is a part of the end surface, and a cooling gas (Ac) flows therein. A plurality of through channel forming surfaces forming the first side through channel (90i) includes a first forming surface (91) that faces a counter flow channel side (Dri) and gradually moves away from the gas path surface (64p) as the same approaches a first end surface (62b). The plurality of end surface spray through channels (71) open at the first forming surface (91) of the first side through channel (90i) and also open at the first end surface (62b).
