Abstract
Official abstract text for this publication.
A fuel nozzle assembly for use in a combustor apparatus of a gas turbine engine. An outer housing of the fuel nozzle assembly includes an inner volume and provides a direct structural connection between a duct structure and a fuel manifold. The duct structure defines a flow passage for combustion gases flowing within the combustor apparatus. The fuel manifold defines a fuel supply channel therein in fluid communication with a source of fuel. A fuel injector of the fuel nozzle assembly is provided in the inner volume of the outer housing and defines a fuel passage therein. The fuel passage is in fluid communication with the fuel supply channel of the fuel manifold for distributing the fuel from the fuel supply channel into the flow passage of the duct structure.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel nozzle assembly in combination with a duct structure in a combustor apparatus of a gas turbine engine comprising: a duct structure comprising: an intermediate duct structure between a liner duct structure and a transition duct and defining a flow passage for combustion gases flowing from said liner duct structure to said transition duct, said intermediate duct structure being free to move axially with respect to each of said liner duct structure and…
