FIELD: engines and pumps.
SUBSTANCE: afterburner combustion chamber of turbojet engine contains chassis, connected to the turbine, nozzle, fuel, or fuel-air collectors, injectors are connected with the jets. The spray nozzles are equipped with micro-swirlers. Each of the micro-swirlers is a cone-shaped nozzle casing with roundings of a small radius R at the base of the cone located near the atomizer. Nozzles with a micro-swirl are connected behind the manifolds by the flow of air so that the injected fuel or fuel-air mixture coincides in the direction of travel with the flow of air and combustion products behind the turbine in the afterburner combustion chamber. At the base of the cone of the nozzle body is a cylindrical spray nozzle.
EFFECT: invention allows to reduce emissions of harmful substances into the atmosphere and decrease the length of the afterburner combustion.
