Abstract: A strainer body strainer body has a conical or bullet-like shape and includes a tip portion, a midsection, and a base portion. The midsection connects the tip portion to the base portion such that the tip portion, midsection, and base portion are aligned with one another along a straining axis defined by the strainer body. The strainer body includes a plurality of layers fused to one another and angled relative to the straining axis. The plurality of layers define flow passages that extend through the strainer body to impound particulate entrained in fluid traversing the strainer body through the flow passages of the strainer body.

Abstract: An injector for a gas turbine engine includes a feed arm including a primary and a secondary fluid passage. An inlet assembly is fixed at an upstream end of the feed arm having at least one inlet in fluid communication with the primary and the secondary fluid passages. A tip assembly is fixed at a downstream end of the feed arm having a fluid outlet in communication with the primary and secondary fluid passages for issuing a spray of fluid. The primary and secondary fluid passages are monolithically formed within the feed arm. At least one of the primary and secondary fluid passages includes a nonlinear section configured to provide increased residence time for cooling fluid in the first and second fluid passages.
