Abstract
Embodiments of a method for manufacturing a turbine engine component are provided, as are embodiments of a thermal growth constraint tool for the manufacture of turbine engine components. In one embodiment, the method includes the steps of obtaining a plurality of arched pieces, arranging the plurality of arched pieces in a ring formation, and bonding the plurality of arched pieces together to produce a monolithic ring by heating the ring formation to a predetermined bonding temperature while constraining the outward radial growth thereof.
Claims20
A method for producing a turbine engine component, comprising:
- obtaining a plurality of arched pieces;
- arranging the plurality of arched pieces in a ring formation;
- and
- bonding the plurality of arched pieces together to produce a monolithic ring by heating the ring formation to a predetermined bonding temperature while constraining the outward radial growth thereof, the step of bonding comprising:
- positioning a thermal growth constraint ring around the ring formation;
- and
- heating the ring formation to a predetermined bonding temperature at which the ring formation grows into the thermal growth constraint ring.
A method for manufacturing a turbine engine component, comprising:
- producing a plurality of arched pieces, each comprising:
- a shank;
- and
- an airfoil extending radially from the shank;
- and
- after producing the plurality of arched pieces to each include a shank and an airfoil extending radially therefrom, bonding the plurality of arched pieces together to form a monolithic airfoil ring, the step of bonding comprising:
- arranging the plurality of arched pieces in a ring formation such that each shank is positioned between two neighboring shanks;
- disposing a thermal growth constraint tool around the ring formation;
- and
- heating the plurality of arched pieces to a predetermined temperature at which outward radial growth of the ring formation is impeded by the thermal growth constraint tool to urge the neighboring shanks together and promote the bonding thereof.
