Abstract (en)
A fuel distributor system for a turbomachine fuel injector can include a plurality of helical fuel flow channels (109) defined between a fuel distributor (107) and a shroud (105) that surrounds the fuel distributor. A wind axis of the helical flow channels is an axial axis of the fuel injector and each of the helical fuel flow channels includes an upstream opening (111) configured to be in fluid communication with a liquid fuel source and a downstream opening (115) configured to effuse fuel therefrom. Each of the plurality of helical fuel flow channels can reduce in flow area from the upstream opening to the downstream opening.
