Abstract (en)
[origin: WO2012104525A1] The aim of the invention is to provide a starting injector that is usable in all flight modes without additional cost or weight. To this end, said starting injector has a specific configuration comprising a dual fuel circuit and an air circuit. For this purpose, an injector (1) for the combustion chamber (3) of a gas turbine comprises a dual fuel injection circuit (C1, C2), consisting of a starting fuel circuit (C1) for ignition and then for all the flight modes, and a main fuel circuit (C2) for all the flight modes after starting. Said circuits (C1, C2) have parallel pipes (12a, 12b) in a common tube (11) having an axis (X'X). The pipe (12a) of the starting circuit is substantially in communication with the center of a spherical injector body. At said end (12e), the pipe accommodates an injection manifold (7) coupled to a central channel (41) passing through a central wall (14) of a swirler (4). The pipe (12b) of the main circuit (C2) is in communication with an annular channel (16) opposite jet channels (42). An air circuit (C3) is guided between two portions shaped as concentric spheres.
