FIELD: mechanical engineering; air-jet engines.
SUBSTANCE: proposed combination air-jet engine contains compressor, primary combustion chambers, gas turbine and reaction nozzle. Outlet combustion chamber arranged after gas turbine and before reaction nozzle communicates either simultaneously or separately with independent gas-air channels provided with separate inlet holes. First of these channels is arranged along engine axis and it is provided with controllable shutoff gate installed on inlet hole and also compressor, primary combustion chambers and gas turbine arranged successively along said axis. Second channel is air duct whose inlet hole is furnished with controllable shutoff gate and pointed to side of front part of engine. Air is arranged along sides of engine, and its outlet hole is arranged over circle in side walls of outlet combustion chamber for directing air flows from air duct concentrically to center of outlet combustion chamber with collision, relative braking and turning of kinetic energy of air flows into additional compression. Outlet combustion chamber is furnished with nozzle to deliver fuel to maximum air compression area.
EFFECT: increased economy of engine.
