Abstract
A method includes (a) depositing a layer (224) of a powder material (216) on a work stage (226), the layer (224) having a thickness, (b) solidifying a portion of the layer (224) based upon data that defines an insert (228) with a body that is shaped to fit into a cavity in a gas turbine engine component, and (c) lowering the work stage (226) by the thickness. Steps (a)-(c) can then be repeated until the insert (228) is complete. The insert (228) can then be removed from the work stage (226). An insert (228) formed by the above process is also disclosed.
Claims12
An insert comprising:
- a body formed by an additive manufacturing process and shaped to fit in a cavity in a gas turbine engine component, the body comprising:
- a base portion that is substantially flat;
- walls extending upwards from the base portion;
- and
- flanges, for attachment to the gas turbine engine component, extending outwards from the walls;
- a hole in the body of the insert;
- and
- a localized build-up adjacent the hole to promote cooling of the component.
A gas turbine engine component with an insert, the component comprising:
- a body with an airfoil running between an outer platform and an inner platform;
- a cavity with an opening on at least one of the outer platform or the inner platform;
- and
- an insert, formed by an additive manufacturing process, placed in the cavity with localized build-up in a pre-selected area to promote cooling of the component.
