Abstract
The results of computer and physical modeling of discharge processes in a new type of pulse-plasma ignition systems for gas turbine engines with a controlled switching spark gap are presented. A circuit design model of a pulse-plasma ignition system has been developed, which makes it possible to evaluate the patterns of discharge processes in a semiconductor spark plug depending on the parameters of the discharge circuits – the capacitances of high-voltage and low-voltage storage capacitors, the inductance of the main discharge circuit. The results of computer simulation are confirmed experimentally, the increased efficiency of the ignition system with a controlled spark gap compared to the known circuit solutions containing two switching spark gaps is substantiated.
