FUEL NOZZLE MANIFOLD SYSTEMS FOR TURBOMACHINES
First Claim
1. An internal fuel manifold for a turbomachine, comprising:
- an outer ring defining one or more fuel supply channels configured to allow fuel flow around at least a portion of a circumference of the outer ring;
a plurality of branches extending radially inward from the outer ring, wherein the branches include a high aspect ratio shape, wherein the plurality of branches include one or more branch fuel channels in fluid communication with at least one of the one or more fuel supply channels;
one or more injector connectors extending axially aft from each branch, each injector connector in fluid communication with a branch fuel channel and configured to connect to a fuel injector; and
an inner ring extending from the plurality of branches, wherein the inner ring and the outer ring are configured to receive a fuel injector and combustor assembly therebetween and to allow retaining of the fuel injector and combustor assembly to the internal fuel manifold.

Abstract
An internal fuel manifold for a turbomachine can include an outer ring defining one or more fuel supply channels configured to allow fuel flow around at least a portion of a circumference of the outer ring, and a plurality of branches extending radially inward from the outer ring. The branches include a high aspect ratio shape. The plurality of branches can include one or more branch fuel channels in fluid communication with at least one of the one or more fuel supply channels. The manifold includes one or more injector connectors extending axially aft from each branch, each injector connector in fluid communication with a branch fuel channel and configured to connect to a fuel injector. The manifold can include an inner ring extending from the plurality of branches. The inner ring and the outer ring are configured to receive a fuel injector and combustor assembly therebetween and to allow retaining of the fuel injector assembly and combustor assembly to the internal fuel manifold.
