FIELD: engines and pumps.
SUBSTANCE: pre-gasified fuel components, helium gas from displacement system and aluminium powder are fed into prechamber for mixing. Further, made mix is fed via peripheral tangential swirler into combustion chamber on the side of nozzle cover. On gyrating along combustion chamber wall toward head section said mix protects combustion chamber walls against heat of active bed of flow part from engine axial section. Presence of helium decreases molecular weight of combustion products to add to engine specific pulse. To increase mix combustion temperature aluminium powder is added thereto.
EFFECT: higher thrust, better protection of chamber housing against combustion product heat.
