FIELD: engines and pumps.
SUBSTANCE: group of inventions relates to devices for igniting the air-fuel mixture in the combustion chambers of gas turbine engines. Combustion chamber of a gas turbine engine contains an outer casing, a flame tube and a nozzle plate of annular shape and an ignition system with a spark plug. Fuel collector is connected to the stove and is installed in the cavity in front of the nozzle plate, the cavity of which is connected on the one hand to the fuel line and on the other to the fuel channels with the nozzle modules. Spark plug is made of laser and installed with an inclination in the direction of the nozzle plate with the possibility of focusing the laser beam at the point of focus between the nozzle plate and the two nozzle modules.
EFFECT: invention is aimed at improving the reliability of ignition of the fuel mixture and preventing the deposition of soot on the optical window of the spark plug.
