Working Principles of an Ion Flyer Composed of Needle and Ring Electrodes
Deportment of Aerospace System Engineering, Tokyo Metropolitan Institute of Technology
(Received August 6, 1988; revised manuscript revised October 14, 1988; accepted for publication October 22, 1988)
The working principles of an ion flyer are explained phenomenally using a simple model composed of a needle electrode and a ring electrode. A positive or negative DC voltage in the region of 0–20 kV is applied to the needle electrode, and the ring electrode is earthed. Thrust, discharge current, and beam current are measured under air pressure in the region of 20–101 kPa. The maximum thrust is 4.6 mN for the applied voltage 20 kV under atmospheric pressure. This ion flyer is useful in a low-gravity or zero-gravity state in an air atmosphere.
