英文摘要：

A technical improvement scheme for aviation engine ignition system is proposed, due to the reason that the existing aircraft engine ignition system uses one machine type and the present situation that the engine ignition systems can not be interchangeable. A general ignition circuit structure and fast special setting method are presented, both of which have been simulated by Muhism software. The simulation results show that the general ignition system for aero-engines can meet the require- ments of ignition technology parameters for all engines by quick setting. The technology has significant influence in improving the generality of aero-engine spare parts, simplifying the engine maintenance system and increasing the warplanes＇ attendance.
