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.
Claims10
A duct for carrying a fluid, the duct comprising:
- a metal tubular element including both a longitudinally varying wall thickness and 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 the fluid from a first portion to another portion;
- and
- wherein the metal tubular element has at least one bend with a radius of curvature that is less than twice a diameter of the metal tubular element.
2 more elements
A fluid delivery system for an engine, comprising:
- at least one metal tubular element that includes a longitudinally varying wall thickness along at least a portion of its length such that the metal tubular element is configured to have at least one of a mechanical property or a thermal property;
- wherein the metal tubular element has at least one curve that includes a radius of curvature less than twice a diameter of the metal tubular element.
