Abstract (en)

The injector has an injector arm with two ducts that are coaxial and supports a spray head, where a peripheral duct (29) of annular section surrounds a central duct (28). The peripheral duct connects a primary fuel circuit that delivers fuel continuously, and the central duct connects a secondary fuel circuit that delivers fuel at a specific rate. The spray head has distributor, and an arrangement of channels that enables a fuel flowing in the central duct to be ejected as a diverging jet situated outside the jet of fuel coming from the peripheral duct. An independent claim is also included for an injector system for injecting fuel into a combustion chamber of a gas turbine engine.
