Aerospace Instrument-Making Annotation << Back MODEL OF THE GTD IGNITION SYSTEM WITH A THREE-ELECTRODE SPARK GAP R.M. Salichov, A.V. Lobanov The results of creating a model of a pulse-plasma ignition system of a gas turbine engine with a threeelectrode spark gap, taking into account the synchronization of processes in discharge circuits, are presented. The model is designed to determine the duration of the discharge depending on the capacity of storage capacitors, inductance of discharge circuits, provided that the specified output energy of the discharge pulses of the ignition system is maintained; the maximum frequency of the discharge pulses of the ignition system; the power consumed by the ignition system in various operating modes. Keywords: pulsed plasma ignition system, three-electrode spark gap, circuit model. DOI: 10.25791/aviakosmos.1.2023.1316 Pp. 19-24.
