FIELD: engines and pumps.
SUBSTANCE: invention may be used in designing combustion chambers of liquid-propellant rocket engine (LPE) incorporating ignition system. Burner plate of liquid-propellant rocket engine combustion chamber comprises housing and fire bottom accommodating fuel nozzle. In compliance with this invention, fuel nozzle face is recessed into fire bottom while variable-section channel is arranged around fuel nozzle in fire bottom to communicate nozzle plate fuel chamber with combustion chamber inner space. Guide ribs are made on fuel nozzle to allow aligning fuel nozzle channel with fire bottom channel minimum section. To eliminate contact of ignition system elements with nozzle plate oxidiser chamber, nozzle fuel feed channels are made in mixing head housing.
EFFECT: higher reliability.
