Abstract

The invention provides a mini-type non-cooling plasma jet igniter which mainly comprises an anode, a cathode, a whirlcone, ceramic parts, a shell, a spring, and an air supply pipeline (cathode connection pipe), wherein parts such as the anode, the cathode and the ceramic parts are pressed and fixed via the shell and the spring; and the cathode is in plug-in connection with the cathode connection pipe. The mini-type non-cooling plasma jet igniter has the advantages that the size is small; the weight is light; the use is convenient; the mounting and the maintenance are simple; the ignition capability is high; and repeated ignition can be realized. The mini-type non-cooling plasma jet igniter can serve as an ignition device for various heaters, combustion chambers, aero-engines and ATR combined engines.

Description

technical field [0001] The invention relates to a plasma jet igniter. Background technique [0002] At present, the ignition devices of aero-engines and ATR combined engines are mostly electric squibs, igniters, and spark plugs. Electric squib and igniter ignition have the disadvantages of poor safety and difficulty in multiple starts, while ordinary spark plug ignition has the disadvantages of low ignition energy and general ignition reliability. Plasma ignition technology is an effective way to improve the ignition reliability of aero-engines and ATR combined engines and realize the functions of multiple ignition and repeated use. However, conventional plasma igniters have shortcomings and deficiencies in terms of airborne assembly, portability, and reliability. Contents of the invention [0003] The invention overcomes the shortcomings and deficiencies of the existing plasma ignition technology in terms of assembly, portability and reliability, and provides a small no...
