FIELD: machine building.
SUBSTANCE: turbomachine annular combustion chamber includes two coaxial circular walls, inner and outer, – connected by their located upstream ends by means of chamber bottom circular wall, containing openings for injection systems installation. Each of injection systems comprises nozzle and at least one spiral element, intended for air swirling flow formation, mixed downstream with fuel supplied from nozzle, and at least one spark plug installed in outer circular wall opening downstream of injection systems. Spark plug is arranged along circumference between two adjacent injection systems, which are made so, that to make fuel-air mixture jets, rotating in opposite directions.
EFFECT: invention is aimed at improvement of fuel-air mixture jets ignition.
