Abstract
A method includes forming fluid conduit inside a heat shield in an additive manufacturing process, removing powder from an interior passage of the fluid conduit and from an insulation gap defined between the fluid conduit and the heat shield, separating the heat shield and fluid conduit from the build platform, and shifting the fluid conduit to a shifted position relative to the heat shield. The method includes securing the fluid conduit to the heat shield in the shifted position.
Claims19
A system comprising:
- a fluid conduit within a heat shield, wherein the fluid conduit includes a series of supports extending therefrom, wherein the heat shield includes a series of apertures therethrough, wherein each support in the series of supports extends through a respective one of the apertures in the series of apertures, wherein the fluid conduit defines multiple separate flow channels therethrough.
A system comprising:
- a fluid conduit within a heat shield, wherein the fluid conduit includes a series of supports extending therefrom, wherein the heat shield includes a series of apertures therethrough, wherein each support in the series of supports extends through a respective one of the apertures in the series of apertures, wherein the fluid conduit defines a ring shaped manifold with a plurality of radially inwardly extending feed arms extending inward from the manifold, wherein the heat shield extends about and shields the manifold and the feed arms.
A system comprising:
- a fluid conduit within a heat shield, wherein the fluid conduit includes a series of supports extending therefrom, wherein the heat shield includes a series of apertures therethrough, wherein each support in the series of supports extends through a respective one of the apertures in the series of apertures, wherein at least some of the apertures through the heat shield are elongated to accommodate relative thermal expansion/contraction between the fluid conduit and the heat shield.
