FIELD: engines and pumps.
SUBSTANCE: claimed engine comprises air intake, gas generator with solid propellant charge in a separate case, after afterburner and nozzle. Operation of this engine under conditions of supersonic combustion comprises the steps that follow. Airflow is subjected to incomplete braking in air intake. Solid propellant is gasified in gas generator. Gasification products are decomposed in the cooling duct. Air and decomposition products are mixed, the mix is ignited and combusted in the afterburner. Combustion products are expanded in the nozzle. Invention discloses also the operation of this engine on solid propellant under conditions of supersonic combustions.
EFFECT: decreased weight and overall dimensions, higher power capacity and fast and completer propellant combustion, reliable protection and cooling of afterburner walls.
