The invention relates to a multi-mode
spiral wave ion thruster and belongs to the field of
aerospace electric propulsion. A
quartz discharging chamber is placed in a Faraday
barrel; an
anode is fixedin an opening end of the
quartz discharging chamber; an opening end of the
quartz discharging chamber is in contact connection with a screen grid; the screen grid, an acceleration grid and a deceleration grid keep a distance; an antenna is mounted on an outer
barrel wall of the quartz discharging chamber; a plurality of spiral coils are mounted on an outer wall of the Faraday
barrel; a
cathode neutralizer is placed at the opening end of the quartz discharging chamber and is used for neutralizing an electrostatic grid
electrode to accelerate led-out
ion beam flow; the
cathode neutralizer and the
anode generate an axial
electric field, a
route of electrons can be effectively increased and the
ionization rate is improved. The thruster provided by the invention is provided with the neutralizerand the neutralizer can be used for neutralizing the
ion beam flow led out from the electrostatic grid
electrode;
cathode and
anode structures are arranged and the axial
electric field can be provided, so that the
ionization rate of plasmas is improved and the production cost of ions can be calculated; the designed
spiral wave ion thruster has the advantages that an additional
magnetic field hasan adjustable bit type and multi-mode working of the thruster can be realized.
