Additively manufactured connection for a turbine nozzle

A turbine nozzle for a gas turbine engine, comprising:

• an arcuate inner band;
• an arcuate outer band;
• and
• a nozzle vane disposed between the arcuate inner band and the arcuate outer band, wherein a radially inner end of the nozzle vane is attached to the arcuate inner band through an interlocking transition zone comprising a plurality of projections alternately extending from the radially inner end of the nozzle vane and the arcuate inner band, respectively, to undetachably couple the nozzle vane and the arcuate inner band,
• wherein a radially outer end of the nozzle vane is attached to the arcuate outer band through an interlocking transition zone comprising a plurality of projections alternately extending from the radially outer end of the nozzle vane and the arcuate outer band, respectively, to undetachably couple the nozzle vane and the arcuate outer band,
• wherein a platform segment is embedded within a radially inner surface of the arcuate outer band, wherein the interlocking transition zone undetachably couples the radially outer end of the nozzle vane to the platform segment,
• wherein the nozzle vane is constructed from a first metal alloy, wherein the platform segment is constructed from a second metal alloy that is different than the first metal alloy, and wherein the arcuate outer band is constructed from a third metal alloy that is different than the first metal alloy and from the second metal alloy.

A turbine nozzle segment for a gas turbine engine, comprising:

• an arcuate inner band;
• an arcuate outer band;
• and
• at least two nozzle vanes disposed between the arcuate inner band and the arcuate outer band,
• wherein a radially inner end of each nozzle vane is attached to the arcuate inner band through an interlocking transition zone comprising a plurality of projections alternately extending from the radially inner end of the nozzle vane and the arcuate inner band, respectively, to undetachably couple each nozzle vane and the arcuate inner band, and
• wherein a radially outer end of each nozzle vane is attached to the arcuate outer band through an interlocking transition zone comprising a plurality of projections alternately extending from the radially outer end of the nozzle vane and the arcuate outer band, respectively, to undetachably couple each nozzle vane and the arcuate outer band.
