Abstract
A duct for a turbine engine, such as a gas turbine engine, can be utilized to carry a fluid from one portion of the engine to another. The duct can include a metallic tubular element having one of a varying wall thickness, a varying cross section, or a tight bend. Such a duct can be formed utilizing additive manufacturing or metal deposition on an additively manufactured mandrel.
Claims20
A duct, comprising a metal tubular element including at least one of a varying wall thickness or a varying cross-section along at least a portion of a length of the metal tubular element and wherein the metal tubular element is configured to convey fluid from a first portion to another portion.
A fluid delivery system for an engine, comprising at least one metal tubular element that includes at least one of a varying wall thickness or a varying cross-section along at least a portion of its length such that the metal tubular element is configured to have at least one of a localized mechanical property or a localized thermal property.
A method of forming a metallic tubular element, the method comprising:
- forming, via additive manufacturing, a sacrificial mandrel having an outer surface with a predetermined geometry;
- depositing metal on the outer surface of the sacrificial mandrel to define the metallic tubular element where depositing metal occurs at temperature that does not damage the sacrificial mandrel;
- and
- removing the sacrificial mandrel from the metallic tubular element.
