Title:
ROTOR BLADE, GAS TURBINE PROVIDED WITH SAME, AND ROTOR BLADE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/047502
Kind Code:
A1
Abstract:
A rotor blade (50) includes a blade path (71) that extends in the blade height direction (Dwh), a platform path (81) formed in a platform (60), and a linking path (75) that connects from the outer surface (93) of an axial mounting section (90) to the blade path (71) via the platform path (81). The inner surface that demarcates an inflow path section (82) of the platform path (81) includes an axial-side inner surface (88) facing the gas path side. The axial-side inner surface (88) broadens in the direction in which there are more blade thickness-direction (Dwt) components than there are blade height-direction (Dwh) components. The inner surface that demarcates the linking path (75) is connected to the axial-side inner surface (88).
