Abstract

The invention relates to an annular combustion chamber for a turbomachine, comprising an external wall (2), an internal wall (3) and a chamber base (4) on which identical injection systems (5) are mounted along at least one ring, said injection systems being intended to mix fuel from the injectors (6) with air from the compressor. The invention is characterised in that at least two injection systems (5) located on the same ring are offset longitudinally in the direction of the central axis of the combustion chamber.
