Abstract: A nozzle for a fuel injector can include an outer air swirler having an inner surface with the outer air swirler having a groove on the inner surface and a prefilmer located concentrically within the outer air swirler with the prefilmer having at least one detent finger to engage the groove on the inner surface of the outer air swirler. The nozzle can also include a fuel swirler located concentrically within the prefilmer and configured to convey fuel to a forward end of the nozzle with the fuel swirler having at least one tab extending axially at an aft end, and an inner air swirler having a cylindrical forward end located concentrically within the fuel swirler and an aft support extending radially outward to contact the outer air swirler with the cylindrical forward end contacting at least one tab of the fuel swirler to hold the fuel swirler in place.

Abstract: One embodiment includes a fuel injector for a gas turbine engine. The fuel injector has an inlet fitting for receiving fuel. The fuel injector also has an outlet fitting for delivering fuel through a nozzle to a combustor of the gas turbine engine. An injector support extends between the inlet fitting and the outlet fitting and has an internal bore therethrough. A fuel tube extends from the inlet fitting through the internal bore of the injector support to the outlet fitting. The injector support has a greater coefficient of thermal expansion than the fuel tube. At room temperature the fuel tube is under compressive stress such that the fuel tube is buckled. As a result of differential thermal expansion of the fuel tube and the injector support during engine operation the fuel tube is relieved of compressive stress.
