FIELD: engines and pumps.
SUBSTANCE: method for supplying fuel components to a chamber of a three-component liquid-propellant engine, mainly of oxygen-kerosene-hydrogen one, consists in supply of the above components to the chamber through coaxial uniaxial-jet injectors containing a hollow tip attaching the oxidiser cavity to combustion zone, a sleeve enveloping the tip with a gap and connecting the fuel cavity to combustion zone, which are located in a mixing head in coaxial circles and forming central and peripheral zones. In the mode of the first stage, oxygen is supplied to the combustion chamber cavity through the hollow tip with developed outlet surface of coaxial uniaxial-jet injector, hydrogen through a shaped gap between the tip and the sleeve of the above injector, kerosene through channels which are made in the sleeve; outlet part of the above channels opens to a cavity that is made in the sleeve housing, and inlet surface is connected to kerosene cavity; the above cavity in the sleeve housing is connected through tangential channels to an annular groove made on the sleeve and connected to combustion zone. In the mode of the second and following stages, oxygen is supplied to the combustion chamber cavity through a hollow tip with developed outlet surface of coaxial uniaxial-jet injector, and hydrogen through the shaped gap between tips and the sleeve of the above injector.
EFFECT: improving completeness of mixture formation.
