COMBUSTION CHAMBER OF LPE WITH ELECTROPLASMA IGNITION Russian patent published in 2017 - IPC F02K9/95 

FIELD: engines and pumps.

SUBSTANCE: combustion chamber of a liquid-propellant rocket engine, fuelled with liquid oxygen and liquid hydrogen or liquid oxygen and liquefied natural gas, contains an ignition device, a chamber housing with fuel supply lines for cooling, a mixing head with fuel supply lines, a gas main with a supply line for oxidative generator gas, according to the invention, the supply of the generator gas through the gas main of the mixing head is carried out along the axis of the combustion chamber, and the ignition devices, fixed to the profile gas duct between the mains of the generator gas and fuel supply, are installed in the bushings located between the rows of mixing elements from the periphery of the fire bottom in the places of the mixing elements.

EFFECT: increasing the reliability of ignition of fuel components in high-thrust LPE combustion chambers, reducing labour intensity and time for maintenance of the combustion chamber and ignition devices.
