Annular combustion chamber in a turbine engine

摘要

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.

1. An annular combustion chamber of a turbine engine, the annular combustion chamber comprising:
an inner wall and an outer wall coaxial with the inner wall forming two surfaces of revolution connected together at upstream ends of the inner and outer walls 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 an ignition spark plug mounted in an orifice in the outer wall downstream from the injection systems, wherein the ignition spark plug is situated circumferentially between adjacent first and second injection systems that are configured to produce two air/fuel mixture sheets rotating in first and second directions, respectively, which are opposite each other, and wherein, in the annular combustion chamber, only the first injection system produces the air/fuel mixture sheet rotating in the first direction.
