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 defines a hollow vascular structure configured to communicate a fluid through the vascular engineered lattice structure. The vascular engineered lattice structure has at least one inlet hole and at least one outlet hole that communicates the fluid into and out of the hollow vascular structure. A method for producing a component is also disclosed.
Claims22
A method for producing a component for a gas turbine engine, comprising the steps of:
- forming a vascular engineered lattice structure formed inside of a wall of the component, with a lattice cavity defined between internal surfaces of said wall and external surfaces of said vascular engineered lattice structure, said vascular engineered lattice structure defining a hollow vascular structure configured to communicate a fluid through said vascular engineered lattice structure, said hollow vascular structure defined by a plurality of nodes and a plurality of branches each extending from at least one of said plurality of nodes, with respective internal passages defined within each node of said plurality of nodes and within each branch of said plurality of branches for communicating fluid, said internal passages being distinct from said lattice cavity;
- and
- said vascular engineered lattice structure having at least one inlet hole and at least one outlet hole that communicate the fluid into and out of said hollow vascular structure.
A component for a gas turbine engine, comprising:
- a wall defining exterior surfaces of said component;
- a vascular engineered lattice structure formed inside of said wall, and interconnected lattice passages defined between internal surfaces of said wall and external surfaces of said vascular engineered lattice structure, said vascular engineered lattice structure defining a solid vascular structure configured to communicate a fluid through said vascular engineered lattice structure, wherein said solid vascular structure includes a plurality of nodes, a plurality of branches that extend between said plurality of nodes, said lattice passages extending between said plurality of nodes and said plurality of branches, and a plurality of augmentation features that each extend outwardly from a respective one of said plurality of nodes or said plurality of branches;
- said vascular engineered lattice structure having at least one inlet hole and at least one outlet hole that communicate the fluid into and out of said solid vascular structure;
- and
- wherein said wall is part of a combustor panel of a gas turbine engine.
A method for producing a component for a gas turbine engine, comprising the steps of:
- forming a vascular engineered lattice structure inside of a wall of the component, said vascular engineered lattice structure having a hollow lattice structure and a solid lattice structure and including at least one inlet hole and at least one outlet hole that communicate a fluid into and out of said vascular engineered lattice structure;
- a lattice cavity is defined between internal surfaces of said wall and external surfaces of said vascular engineered lattice structure;
- and
- each of said hollow lattice structure and said solid lattice structure is defined by a plurality of nodes and a plurality of branches each extending from at least one of said plurality of nodes, with at least some of said plurality of branches being spaced apart from internal surfaces of said wall defining said lattice cavity such that fluid is communicated in said lattice cavity around and over said plurality of nodes and said plurality of branches.
