Abstract
A vacuum cathode arc-induced pulsed thruster includes a housing where a triggering room and an electric discharging room are defined and are in communication with each other, a first anode unit and a first cathode unit concentrically disposed in the triggering room, a second anode unit disposed in the electric discharging room, an insulating fuel layer concentrically located between the first anode unit and the first cathode unit, a main insulating layer concentrically surrounded by the first cathode unit, and a second cathode unit inserted from the triggering room into the electric discharging room. Thus, the vacuum cathode arc-induced pulse thruster is lightweight and has low manufacturing costs, low system complexity, and less energy consumption. Carbon deposition caused during an electric discharging process is prevented from affecting an inducing effect to thereby prolong the service life of the thruster and increase the control precision and inducing precision effectively.
