Thermionic emission of electrons is utilized to initiate arc discharge in a pulsed plasma thruster.
1. A pulsed plasma thruster comprising:a pair of electrodes being: an anode; and a cathode spaced apart from the anode; a voltage source for applying a voltage between the cathode and the anode to positively charge the anode relative to the cathode; a solid propellant bar extending longitudinally and held for progressive advancement in a downstream longitudinal direction to a gap between the cathode and anode; and an initiator for initiating arc discharge between the anode and cathode by inducing thermionic emission of electrons, which electrons are draw...
