Thrust measurements in ionic systems with toroidal and cylindrical counter electrodes (the toroid minimum diameter is 17 cm and equal to the cylinder electrode). (a) Variation of the ionic axial thrust with rotational speed in RIEs with toroidal and cylindrical counter electrodes (b) Variation of the ionic axial thrust with current in RIEs with toroidal and cylindrical counter electrodes; additional comparison is made for systems with a blocked ionic propeller and for systems using the shaft/pin as emitter. (c) Variation of the ionic axial thrust with voltage (d) Current–voltage characteristics of the studied configurations.
