Theoretical determination of the energy parameters of spark discharges in semiconductor spark plugs of aircraft engines

Abstract

The results of the development of a computer model that allows, without conducting experimental studies of discharge processes in capacitive ignition systems of an oscillatory and aperiodic discharge, to estimate the energy efficiency of the developed and future ignition systems are presented. The proposed model is based on a theoretical description of the laws of the time variation of the discharge current and voltage in semiconductor spark plugs, taking into account the actual current-voltage characteristics of the discharges.
