Abstract
An annular combustion chamber of a turbine engine, the chamber including inner and outer coaxial walls forming two surfaces of revolution, which are connected together upstream by an annular chamber end wall including injection systems passing therethrough, each including an injector and at least one swirler for producing a rotating air stream that mixes downstream with fuel from the injector, and at least one ignition spark plug mounted in an orifice of the outer wall downstream from the injection systems. The spark plug is situated circumferentially between two adjacent injection systems that are configured to produce two air/fuel mixture sheets rotating in opposite directions.

An annular combustion chamber of a turbine engine, the chamber comprising:
- inner and outer coaxial walls forming two surfaces of revolution connected together at their upstream ends by an annular chamber end wall comprising openings for mounting injection systems, each opening comprising an injector and at least one swirler for producing a rotating air stream that mixes downstream with fuel coming from the injector;
- and
- at least one ignition spark plug mounted in an orifice in the outer wall downstream from the injection systems,
- wherein the spark plug is situated circumferentially between two adjacent injection systems that are configured to produce two air/fuel mixture sheets rotating in opposite directions.
