Abstract
A plasma motor for extracting a positive ion flow has a single ionization stage and a device for supplying the ionization stage with an ionizable electronegative gas. The plasma motor further has a device for creating an electric field so as to produce the ionization of the gas in the ionization stage. The device for creating the electric filed includes a device for extracting a negative ion flow and, a device for extracting a positive ion flow, connected to the ionization stage. The extraction of a positive ion flow and the extraction of a negative ion flow are of the same amplitude, ensuring the electrical neutrality of the motor. The extraction of a positive ion flow and the extraction of a negative ion flow allow the neutrality of the motor to be ensured.
