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.
Claims17
A component, comprising:
- a wall defining exterior surfaces of the 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 includes at least a solid vascular structure configured to communicate fluid through said vascular engineered lattice structure, wherein said solid vascular structure is defined by a first set of nodes interconnected to a first set of branches, with fluid communicated in said lattice passages around and over said first set of nodes and said first set of branches;
- wherein said first set of branches and said first set of nodes are non-uniformly distributed throughout said vascular engineered lattice structure, and at least some of said first set of branches and at least some of said first set of nodes are spaced apart from each of said internal surfaces of said wall;
- wherein said vascular engineered lattice structure includes a hollow vascular structure in which airflow is communicated inside hollow passages of a second set of nodes and a second set of branches of said vascular engineered lattice structure;
- wherein a first portion of said vascular engineered lattice structure includes said hollow vascular structure and a second portion of said vascular engineered lattice structure includes said solid vascular structure;
- wherein said second set of nodes are interconnected to said second set of branches, with a plenum defined within each node of said second set of nodes, and with an internal passage defined within each branch of said second set of branches, each said internal passage being discrete and interconnected with a respective one of said plenum for communicating fluid, each said internal passage and each said plenum being distinct from said lattice passages;
- and
- wherein said wall is part of a combustor panel of a gas turbine engine.
