等离子流点火技术是当今世界上一项比较先进的行之有效的化学燃料燃烧点火技术。目前,在航空、航天以及难以燃烧燃料的点火技术领域上,竞争得十分激烈。 为满足先进的高性能航空发动机的需要,近来,沈阳航空发动机研究所对该技术进行了深入的研究,并已取得很大的进展。预研工作包括先期研究和实用化研究两个阶段。在先期研究阶段中,研制的原型等离子流点火系统,其演示试验获得成功,并较理想地解决了系统重量控制、点火器尺寸控制和电磁屏蔽等技术关键。现正进行系统的实用化改进,主要 Plasma flow ignition technology is a more advanced and effective chemical fuel combustion ignition technology in the world today. At present, there is fierce competition in the field of ignition technology for aviation, spaceflight and hard-to-burn fuels. To meet the needs of advanced high-performance aeroengine, Shenyang Aeronautical Research Institute recently conducted in-depth research on the technology and made great progress. Pre-research work includes two stages of pre-research and practical research. In the early stage of research, the prototype plasma flow ignition system was developed, the demonstration test was successful, and the key technologies of system weight control, size control of igniter and electromagnetic shielding were ideally solved. The practical improvement of the system is underway
