FIELD: engines and pumps.
SUBSTANCE: gas-turbine engine combustion chamber comprises a case, a fuel-air channel with a fuel spray nozzle and a plug. The combustion chamber is direct-flow accomplished. The fuel-air channel is axially set to the case and is attached to it. There is a register with a blade twist angle 60±5° in the case on the bullet. The fuel film is formed on the case internal surface by means of the centrifugal forces of the fuel-air swirling flow.
EFFECT: toxicity reduction, efficiency upgrading, start when burning the lean air-fuel mixture reliability enhancement.
