Fuel injecting system for e.g. axial/bent combustion chamber of turbojet engine, has fuel injector positioned at center of system to inject fuel cloud, and another fuel injector surrounding former injector to inject annular fuel cloud

摘要

The system (20) has a fuel injector (22) positioned at the center of the injecting system in order to inject a fuel cloud (42). Another fuel injector (28) surrounds the fuel injector (22) in order to inject an annular fuel cloud (48) around the fuel cloud (42). Air inlet passages (24, 30) e.g. air spins, respectively associated to the two injectors for forming two air/fuel mixtures, respectively.
