Abstract: This paper describes the working principle of the aircraft engine ignition system, and discusses the factors which affect the minimum ignition voltage of the semiconductor igniter according to the fomula derivation. From the bad environment of the igniter tip, the electrode materials that satisfy the requirement is listed. At the same time, the relationship between the electrode gap, the energy storage capacity and the minimum ignition voltage is investigated based on the practical test data. The calculation progress of electrode gap design is stated in detail through nonlinear analysis, and then provides the basis for reasonable choice of the electrode gap of semiconductor igniter.
