Abstract
The efficiency of new oscillator connection diagrams in plasma ignition systems (PISs) of gas-turbine engines (GTEs) is analyzed. The most efficient oscillator connection diagram is found that reduces losses in the power circuit of the ignition system with an increased ignition capacity of the plasmatron. There are two types of discharges in the plasmatron: a continuous arc discharge and a pulsed capacitive discharge, the instantaneous power of a short capacitive discharge being several orders of magnitude higher than the instantaneous power of the arc discharge. The dynamics of discharge processes in the oscillator is estimated. Analytical expressions are presented for the main parameters of pulsed discharges: the maximum discharge current and the energy and duration of discharges.
