Document Type and Number:
Japanese Patent JP6372210
Kind Code:
B2
Abstract:
A stator vane arranged around an axis to form a turbine nozzle is comprised of: an airfoil section elongated in a radial direction relative to the axis; an outer band section continuous to an outer end of the airfoil section and bent in a circumferential direction relative to the axis; a first hook section continuous to a leading end in the axial direction of the outer band section and bent outward in the radial direction; a second hook section continuous to a trailing end in the axial direction of the outer band section and bent outward in the radial direction; an inner band section continuous to an inner end of the airfoil section and bent in the circumferential direction; a flange section continuous to an end in the axial direction of the inner band section and bent inward in the radial direction; and a reinforcement fiber fabric continuous throughout the airfoil section, the outer band section, the first hook section, the second hook section, the inner band section and the flange section and unitized with a ceramic.
