摘要： A method of assembling a fuel nozzle includes providing a first nozzle component and a second nozzle component, wherein the first nozzle component is configured and adapted to engage within the second nozzle component. Braze is applied to at least one of the first and second nozzle components. The first nozzle component is assembled into the second nozzle component to provide a diametral interference fit therebetween. The method further includes joining the first and second nozzle components together. A fuel nozzle includes a first cylindrical nozzle component, a second cylindrical nozzle component disposed with an interference fit on an outward surface of the first nozzle component, and a layer of braze joiningly disposed between the first and second nozzle components.

摘要： A staged fuel injector is disclosed that includes a main fuel circuit for delivering fuel to a main fuel atomizer and a pilot fuel circuit for delivering fuel to a pilot fuel atomizer located radially inward of the main fuel atomizer. The pilot fuel circuit is in close proximity to the main fuel circuit enroute to the pilot fuel atomizer so that the pilot fuel flow cools stagnant fuel located within the main fuel circuit during low engine power operation to prevent coking.
