Abstract

A component according to an exemplary aspect of the present disclosure includes, among other things, a wall and a vascular engineered lattice structure formed inside of the wall. The vascular engineered lattice structure includes at least one of a hollow vascular structure and a solid vascular structure configured to communicate fluid through the vascular engineered lattice structure.

Claims (31)

1. A component, comprising:

a wall;

a vascular engineered lattice structure formed inside of said wall, with a lattice cavity defined between internal surfaces of said wall and external surfaces of said vascular engineered lattice structure; and

said vascular engineered lattice structure including at least a hollow vascular structure configured to communicate fluid through said vascular engineered lattice structure, said hollow vascular structure defined by a first set of nodes and a first set of branches each extending from at least one of said first set of nodes, with respective internal passages defined within each node of said first set of nodes and within each branch of said first set of branches for communicating fluid, said internal passages being distinct from said lattice cavity.

2. The component as recited in claim 1 , wherein said vascular engineered lattice structure includes a solid vascular structure in which fluid is communicated in said lattice cavity around and over a second set of nodes and a second set of branches of said vascular engineered lattice structure.

3. The component as recited in claim 2 , wherein each of said second set of nodes and said second set of branches being free of any internal passages.

4. The component as recited in claim 1 , wherein said wall is part of an airfoil, a blade, a vane, a blade outer air seal (BOAS), a combustor panel or a turbine exhaust case of a gas turbine engine.

5. The component as recited in claim 1 , wherein said vascular engineered lattice structure is a co-flow vascular engineered lattice structure or a counter-flow vascular engineered lattice structure.

6. The component as recited in claim 1 , wherein said vascular engineered lattice structure is formed using an additive manufacturing process.

7. The component as recited in claim 1 , wherein said vascular engineered lattice structure is a curved or arcuate structure disposed in a leading edge of said component.

8. The component as recited in claim 1 , wherein said vascular engineered lattice structure is an axial jumper vascular engineered lattice structure.

9. The component as recited in claim 1 , wherein said vascular engineered lattice structure is a radial flow vascular engineered lattice structure.

10. The component as recited in claim 1 , wherein said vascular engineered lattice structure is axially and radially tapered.

11. The component as recited in claim 1 , wherein a height of said vascular engineered lattice structure is tapered in a streamwise direction.

12. The component as recited in claim 1 , wherein said vascular engineered lattice structure includes at least two separate axial flow vascular engineered lattice structures.

13. The component as recited in claim 1 , wherein said wall includes a first wall portion and an opposed, second wall portion, said first wall portion defines external surfaces of said component, said second wall portion bounds an internal cooling cavity, and said lattice cavity is defined between said first wall portion and said second wall portion.

14. The component as recited in claim 13 , wherein at least some branches of said first set of branches extend from said internal surfaces of said wall.

15. A method for producing a component, comprising the steps of:

forming a vascular engineered lattice structure inside of a wall of the component, said vascular engineered lattice structure having at least a hollow lattice structure, with a lattice cavity defined between internal surfaces of said wall and external surfaces of said vascular engineered lattice structure; and

wherein said hollow lattice structure is defined by a first set of nodes and a first set of branches each extending from at least one of said first set of nodes, with respective internal passages defined within each node of said first set of nodes and within each branch of said first set of branches for communicating fluid, said internal passages being distinct from said lattice cavity.

16. The method as recited in claim 15 , wherein the step of forming the vascular engineered lattice structure includes utilizing direct metal laser sintering (DMLS).

17. The method as recited in claim 15 , wherein the step of forming the vascular engineered lattice structure includes utilizing electron beam melting (EBM).

18. The method as recited in claim 15 , wherein the step of forming the vascular engineered lattice structure includes utilizing select laser sintering (SLS).

19. The method as recited in claim 15 , wherein the step of forming the vascular engineered lattice structure includes utilizing select laser melting (SLM).

20. The method as recited in claim 15 , comprising the step of:

communicating fluid inside of said internal passages where the vascular engineered lattice structure embodies the hollow lattice structure.

21. The method as recited in claim 15 , wherein the step of forming the vascular engineered lattice structure includes:

forming a core using an additive manufacturing process; and

using the core to cast the vascular engineered lattice structure.

22. The method as recited in claim 19 , wherein the additive manufacturing process includes powder bed technology and the vascular engineered lattice structure is cast using a lost wax process.

23. The method as recited in claim 15 , wherein said vascular engineered lattice structure including a solid lattice structure, and further comprising the step of communicating fluid in said lattice cavity around and over a second set of nodes and a second set of branches of said solid lattice structure, each of said second set of nodes and said second set of branches being free of any internal passages.
