摘要：
According to the position of gliding arcs, four kinds of rotating gliding arc swirlers were designed and manufactured based on the beveled holes and radial vanes swirlers commonly used in medium and small aero-engine combustors. The discharge test at cold state and ignition test were performed. The results of discharge test showed that the four swirlers could produce stable rotating gliding arcs at specific position. Ignition tests were performed based on a triple combustor. The ignition tests showed that, scheme 4 had the best ignition performance and the smallest ignition fuel-air ratio was lower if compared with conventional ignition method. The ignition performance of scheme 2 was worse than that of scheme 4. The combustor could only be ignited when the reference speed was low for scheme 3, and scheme 1 showed the worst ignition performance. The air speed and distribution of fuel air at local position of gliding arcs had a significant influence on the ignition performance and the recommended air speed was not more than 20 m/s. © 2023 BUAA Press.
