    Abstract: A gas turbine engine includes a combustion section, the combustion section including a plurality of fuel nozzles. A fuel delivery system for the gas turbine engine includes a feed tube and a fuel manifold fluidly connected to the feed tube for receiving fuel from the feed tube. The fuel delivery system also includes a pigtail fuel line fluidly connected to the fuel manifold and configured to fluidly connect to a fuel nozzle of the plurality of fuel nozzles when the fuel delivery system is installed in the gas turbine engine. In order to reduce an amount of hydraulic instability of a fuel flow through the fuel delivery system, at least one of the fuel manifold or the pigtail fuel line includes a means for damping a hydraulic instability within the fuel delivery system.

    Abstract: A gas turbine engine is provided. The gas turbine engine includes a compressor assembly and a combustion assembly in flow communication with the compressor assembly. The combustion assembly includes a plurality of fuel nozzles and a fluid conduit for delivering fuel to the fuel nozzles. The fluid conduit has a plurality of first outlet ports that are spaced apart from one another along the fluid conduit, and the fluid conduit also has a plurality of second outlet ports that are spaced apart from one another along the fluid conduit. The fluid conduit further has a first flow path extending along the fluid conduit in flow communication with the first outlet ports, and the fluid conduit also has a second flow path extending along the fluid conduit in flow communication with the second outlet ports. At least a portion of the first flow path is circumscribed by the second flow path.
