Abstract

The invention discloses a torch type electric ignition device for gaseous hydrogen and gaseous oxygen. The electric ignition device comprises a hydrogen bottle (1), an oxygen bottle (2), an oxygen sonic nozzle (3), a hydrogen sonic nozzle (4), an ignition body, a convergence section (8) and an electric spark plug device (9); an oxygen cavity (5), a hydrogen cavity (6) and an ignition chamber (7) are arranged in the ignition main body; the hydrogen bottle (1) communicates with the hydrogen cavity (6) of the ignition main body through the hydrogen sonic nozzle (4); the oxygen bottle (2) communicates with the oxygen cavity (5) of the ignition main body through the oxygen sonic nozzle (3); a direct flow hole is formed in the central axis of the ignition chamber (7) and communicates with the oxygen cavity (5); tangential holes (71) are formed in the side wall of the ignition chamber (7) and communicate with the hydrogen cavity (6); the ignition chamber (7) communicates with the convergencesection (8); and the electric spark plug device (9) is installed on the outer surface of the ignition main body, is inserted into the ignition chamber (7) and is located between the direct flow hole and the tangential holes (71).

Description

technical field [0001] The invention relates to a gas-hydrogen-oxygen torch type electric ignition device, which belongs to the technical field of ignition and combustion. Background technique [0002] The torch-type electric igniter has been widely used in hydrogen-oxygen rocket engines because of its high ignition energy, multiple starts, simple structure, and easy maintenance, such as the RL-10 series in the United States, the J2 engine, and the main engine of the space shuttle. Vinci, Japan's LE series engines, Russia's RD-0120, etc. A torch-type electric igniter generally includes three parts: an ignition chamber, a propellant supply system and an electric spark plug system: the propellant enters the ignition chamber through the supply system, is ignited by the electric spark plug, organizes combustion in the ignition chamber, and ignites the downstream after the high-temperature gas is ejected. Burning device. The scope of application of the existing technology is al...
