Abstract
A core for use in casting an internal cooling circuit within a gas turbine engine component includes a base core portion and an additive core portion additively manufactured to the base core portion. A method of manufacturing a core for use in casting an internal cooling circuit within a gas turbine engine component including additively manufacturing an additive core portion to a base core portion.
Claims13
A core for use in casting an internal cooling circuit within a gas turbine engine component, the core comprising:
- a base core portion manufactured of a first crushable material without at least one portion of the internal cooling circuit;
- and
- an additive core portion additively manufactured to the base core portion, the additive core portion comprising the at least one portion of the internal cooling circuit to form a complete internal cooling circuit, the additive core portion manufactured of a second crushable material, the second crushable material less crushable than the first crushable material.
A core for use in casting an internal cooling circuit within a gas turbine engine component, the core comprising:
- a base core portion manufactured of a first crushable material without a trailing edge and at least one portion of the internal cooling circuit;
- and
- an additive core portion additively manufactured to the base core portion, the additive core portion comprising the trailing edge and the at least one portion of the internal cooling circuit to form a complete internal cooling circuit, the additive core portion manufactured of a second crushable material, the second crushable material less crushable than the first crushable material.
