FLAT JET FUEL INJECTOR FOR AN AIRCRAFT TURBOMACHINE

摘要

A flat jet fuel injector for an aircraft turbomachine, comprising a body (112) of generally elongate shape having an axis of elongation A, said body having a main duct (118) of generally elongate shape having an axis of elongation B substantially perpendicular to said axis of elongation A, said main duct having its two longitudinal ends (120) which are respectively connected to longitudinal ends of two secondary ducts (119) of generally elongate shape having an axis of elongation C at least substantially parallel to said elongation axis A, and which are configured to respectively form two separate fuel flow inlets intended to meet substantially in the middle of said main duct which comprises at least one slot (124) for ejecting said jet of fuel, characterized in that at least one of said primary and secondary ducts defines a passage section of which at least one ins a geometric parameter, such as the shape or a dimension, varies along said path and / or is different from the same geometrical parameter defined by a passage section of another said path.
