Air-breathing engine plasma ignition system

Abstract

The invention discloses an air-breathing engine plasma ignition system, and belongs to the technical field of engine ignition. The system involves an air introducing pipeline, an oil supplying pipeline, a power supply and an igniter shell; a high-voltage electrode and a low-voltage electrode are arranged in the igniter shell, the high-voltage electrode and the low-voltage electrode are both hollowcylinders, the low-voltage electrode is coaxially arranged at the exterior of the high-voltage electrode, and an annular cavity is formed between the high-voltage electrode and the low-voltage electrode; the two ends of the oil supplying pipeline communicate with an oil supplying system of an engine and the annular cavity in the igniter shell; the two ends of the air introducing pipeline communicate with an air inlet of the engine and the annular cavity in the igniter shell; and the power supply is arranged in the engine shell and is electrically connected with the high-voltage electrode andthe low-voltage electrode in the igniter shell through wires. The ignition system has the characteristics of being high in system integration, wide in ignition range and excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of engine ignition, and in particular relates to an air-breathing engine plasma ignition system. Background technique [0002] In order to meet the needs of wide-area, long-distance, and high-speed aircraft, the engine will be subject to instantaneous or continuous complex disturbances when it is changing stages, large maneuvering flight, or working conditions, which will easily cause the engine to stall. Therefore, the engine is required It has the ability of quick response, reliable and stable operation and multiple ignition in a large airspace. [0003] At present, domestic and foreign air-breathing engines usually use pyrotechnic igniters and spark plug igniters as ignition devices. Among them, pyrotechnic igniters have good ignition performance and short ignition delay time, but they cannot achieve multiple ignitions of the engine, and spark plug ignition cannot meet the requirements. Engine wide area ...
