ROTOR BLADE, AXIAL FLOW TYPE COMPRESSOR, AND MOUNTING METHOD OF ROTOR BLADE

摘要

PROBLEM TO BE SOLVED: To provide a rotor blade which is sufficiently firmly fixed to a disc with a simple constitution, an axial flow type compressor, and a mounting method of the rotor blade.;SOLUTION: A rotor blade 10 has a core member 12 and reinforcement fiber 14. The core member 12 is extended along a blade length direction as a direction of connecting a blade top side and a blade root side of the rotor blade 10, and has a projecting portion 16a serving as a connecting portion to be connected to a disc disposed on a rotating shaft, at the blade root side. The reinforcement fiber 14 is disposed along an outer periphery of the core member 12, and constitutes a composite material. The projecting portion 16a serving as the joining portion is formed to project in a manner of being extended along a blade width direction as a direction of connecting a front edge side and a rear edge side of the rotor blade 10. The projecting portion 16a fixes the core member 12 to the disc 22 so that it does not move in a blade thickness direction as a direction of connecting a back side and a berry side of the rotor blade 10 and the blade width direction.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
