Casing with tunable lattice structure

摘要: Casings and methods for manufacturing casings are provided. For example, a casing defining radial, axial, circumferential directions is The comprises an annular inner wall outer wall, each extending along the axial direction, with radially spaced apart from wall. also auxetic structure to including plurality of lattice elements. Each element extends circumferentially elements axially one another. may define at least aperture fluid flow portion another and/or be configured vary thermal characteristics direction. integrally formed as single monolithic component, e.g., by additive manufacturing.
