  • Electric propulsion
    Patent number: 9103329
    Abstract: An electric propulsion system comprising a plasma chamber having first and second apertures for producing ion beams. Respective first and second coils are arranged about the chamber to produce an electromagnetic field in regions adjacent to the apertures, and are driven differentially by a radio frequency (RF) drive module. By driving the coils differentially, the electric field in the region of the two apertures can be differentially controlled, and a variation of output thrusts at the two apertures is possible. In this way a net thrust can be produced, which net thrust is varied by controlling the drive to the two coils.
    Type: Grant
