METHOD OF LAUNCH AND POWER SUPPLY OF ELECTROJET PLASMA ENGINE (VERSIONS) AND DEVICE FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2009 - IPC H05H1/54 F03H1/00 H05B37/00 

FIELD: motors and pumps.

SUBSTANCE: invention relates to methods and devices for operation of electrojet plasma engine. Method includes closure of power supply switch and feeding of voltage from power supply for anode and cathode, closure of launching switch and creation of current by at least in one coil of electrojet plasma engine and in connected in turn into electric circuit motor of winding of electro-valves for feeding of actuating medium into anode and cathode, time delay and following breaking of launching switch, formation of high-voltage pulse between cathode and igniter electrode, and ignition of launching discharge between igniter electrode and cathode, which then initiates ignition of main discharge between anode and cathode, with feeding of voltage of its high-voltage pulse simultaneously applied between anode and cathode, and also, through blocking capacitor, between igniter electrode and cathode, and coil is additionally used in the capacity of field magnet and closure of launching switch is implemented for time of its charging, which is taken into account in time delay before disconnection of launching switcher.

EFFECT: invention is directed to reliability growth of electrojet plasma engines and decreasing of its mass.
