Abstract
An article of manufacture includes an article body portion (36); at least one pedestal (58A, 60A, 84, 86) integrally formed with the article body portion (36), and disposed at an outer periphery of (52), and structurally coupled to the article body portion (36); and at least one internal feature (72) disposed at least partially within the article body portion (36) and at least partially within the pedestal (58A, 60A, 84, 86). At least a portion of the internal feature (72) is hollow.

An article of manufacture comprising:
- an article body portion (36);
- at least one pedestal (58A, 60A, 84, 86) integrally formed with the article body portion (36), the at least one pedestal (58A, 60A, 84, 86) disposed at an outer periphery (52) of the article body portion (36), and structurally coupled to the article body portion (36);
- and
- at least one internal feature (72), the at least one internal feature (72) disposed at least partially within the article body portion (36) and at least partially within the at least one pedestal (58A, 60A, 84, 86),
- wherein at least a portion of the at least one internal feature (72) is hollow.
An article comprising:
- an airfoil body (36), the airfoil body (36) extending from a leading edge (44) to a trailing edge (46), the airfoil body extending from a pressure side (50) to a suction side (52), the airfoil body (36) extending from a root portion (48) to a tip portion (42);
- at least one internal cavity (54) disposed within the airfoil body (36);
- at least one pedestal (58A, 60A, 84, 86) integrally formed with the airfoil body (36), the at least one pedestal (58A, 60A, 84, 86) protruding from an outer periphery (52) of the airfoil body (36), the at least one pedestal (58A, 60A, 84, 86) structurally coupled to the airfoil body (36);
- and
- at least one film cooling hole (72), the at least one film cooling hole (72) disposed at least partially within the airfoil body (36) and at least partially within the at least one pedestal (58A, 60A, 84, 86),
- wherein the at least one film cooling hole (72) is in fluid communication with the at least one internal cavity (54).
A method of forming a component comprising:
- selecting an orientation for the component (36) being formed such that one or more structure (58A, 60A, 84, 86) aligns with at least one feature (72) of the component (36);
- forming the component (72) and the one or more structure (58A, 60A, 84, 86) with the one or more structure (58A, 60A, 84, 86) disposed on the at least one feature (72);
- coating the component (72) and the one or more structure (58A, 60A, 84, 86);
- and
- blending at least one surface of the component (72) with at least one surface of the one or more structure (58A, 60A, 84, 86);
- wherein the at least one feature (72) is disposed at least partially in the component (36) and at least partially in the one or more structure (58A, 60A, 84, 86).
