Abstract
One exemplary embodiment of this disclosure relates to a gas turbine engine, including a component having a first portion formed using one of a casting and a forging process, and a second portion formed using an additive manufacturing process.
Claims13
A method of forming a component of a gas turbine engine, comprising:
- forming a first portion of the component using one of a casting and a forging process, the first portion including a root, platform, and at least one radial support projecting from the platform;
- additively manufacturing a second portion of the component, the second portion providing a side wall of the component;
- and
- joining the second portion to the first portion;
- wherein the step of additively manufacturing the second portion includes directly additively building the second portion onto the first portion, wherein the at least one radial support of the first portion is used as a base for the additive build occurring during the step of additively manufacturing the second portion such that the step of joining the second portion to the first portion occurs concurrent with the step of additively manufacturing the second portion.
