Multimode injection system for a combustion chamber, particularly of a gas turbine

The multi-mode injector for a combustion chamber has at least two coaxial fuel atomising systems. It has a peripheral system with an annular distribution chamber in communication with a series of equally- spaced fuel ejection holes (31) and an annular air deflector with fins (35) forming air ejectio...

Zusammenfassung:The multi-mode injector for a combustion chamber has at least two coaxial fuel atomising systems. It has a peripheral system with an annular distribution chamber in communication with a series of equally- spaced fuel ejection holes (31) and an annular air deflector with fins (35) forming air ejection channels (36) for each of the holes. The number of channels is equal to or a multiple of the number of holes, and a median line (M) at least drawn through the inner end of each channel intersects one of the holes.
