Abstract
A process for additively controlled surface features of a gas turbine engine casing. The process comprises forming the casing having an inner surface and an outer surface opposite the inner surface; forming a surface feature on the casing proximate the inner surface, wherein the surface feature comprises a structure on the inner surface configured to align or misalign with respect to a flow direction of a working fluid in a flow path of the casing.
Claims5
A process for additively controlled surface features of a gas turbine engine casing comprising:
- forming the casing having an inner surface and an outer surface opposite said inner surface
- forming a surface feature on said casing proximate said inner surface, wherein said surface feature comprises a structure on said inner surface configured to at least one of align and misalign with respect to a flow direction of a working fluid in a flow path of said casing;
- wherein said surface feature is a scallop shaped formation, wherein the scallop shaped formation resembles a surface of scales of fish and snakes that align in a common direction.
