ADDITIVELY MANUFACTURED COMBUSTOR SHELL WITH CONSUMABLE SUPPORT STRUCTURES

摘要

An additively manufactured combustor shell (104, 106) may comprise a radially outward surface (108), a radially inward surface (110) opposite the radially outward surface (108), and an injector port (120) defining a fuel injection channel (122). The injector port (120) may comprise an inlet structure (124) extending from the radially outward surface (108), and an outlet structure (126) may extending from the radially inward surface (110). A support structure (130) may extend between the outlet structure (126) and the radially inward surface (110). The support structure (130) may be configured to vaporize upon ignition of a fuel within the combustion chamber.
