Helicon plasma induction thruster

The invention discloses a helicon plasma induction thruster. The helicon plasma induction thruster comprises a discharge cavity, and first magnets and second magnets are sequentially arranged on the outer portion of the discharge cavity; a helicon discharge antenna and an induction acceleration coil are sequentially arranged on the outer wall of the discharge cavity in the axial direction; and the thruster further comprises a helicon discharge circuit, a pulse induction discharge circuit and a time sequence control circuit, wherein the helicon discharge circuit provides a work power source for the helicon discharge antenna. The pulse induction discharge circuit is connected with the induction acceleration coil and provides a pulse discharge voltage for the induction acceleration coil so as to drive helicon plasmas to be pushed out in an accelerated manner, and the time sequence control circuit is connected with the helicon discharge circuit and the pulse induction discharge circuit. The helicon plasma induction thruster has the beneficial effects of being free of electrode corrosion, large in ionization density and long in service life. Through efficient decoupling of the ionization level and the acceleration level, efficient separation of the ionization level and the acceleration level is achieved, voltage needed by a capacitor of the acceleration level is reduced, the system size and the system weight are greatly reduced, and miniaturization, lightweight and the solid state of the thruster are facilitated.
