Concepts for micro-thrusters based on solid state ion conductors

Описание материала

We present two concepts for electric micropropulsion thrusters based on the ion conductor yttria stabilized zirconia (YSZ). One of the concepts is based on microfabricated YSZ membranes where oxygen from the gas phase out of a reservoir is incorporated in the form of ions at the YSZ surface and conducted through the membrane to the opposite surface where it is extracted as O- and accelerated into vacuum. The other approach is based on an oxygen-rich thick YSZ film where the excess oxygen is extracted from the layer and accelerated into vacuum. First results of the realization of such devices are shown and the corresponding measurement set-ups for the characterization are discussed.
