FIELD: engines.
SUBSTANCE: invention relates to devices for mixing and spraying fuel components of a liquid-propellant engine (LPE). Two-component gas-liquid nozzle contains a housing, inside which a tube is fixed on pylons, a branch pipe installed coaxially in the outlet part of the housing and on the cylindrical surface of which there are tangential holes connecting the stepped expansion formed by the branch pipe and the housing, with the fuel cavity. Inside the tube there is a bushing, in the outlet part of which there are screw channels interconnected with the fuel cavity through an annular channel between the tube and the bushing, and radial holes made in the pylons.
EFFECT: invention increases completeness of combustion of fuel components due to improved quality of mixture formation.
