摘要：

Recently, studies on ion wind generators using corona discharge are actively being conducted. This is mainly used in cooling of electronics or in ion thrusters using thrust force of ion winds. The existing ion wind generators are only composed of corona electrodes and induction electrodes, so the acceleration region of ions and electrons is very limited. This paper measured the changes in the average speed of ion winds according to changes in the number of acceleration electrodes and the applied voltage by additionally installing acceleration electrodes in addition to corona electrodes and induction electrodes, and verified experimentally that the speed of ion winds can be increased by expanding the acceleration region of ions via multistage application of acceleration electrodes.
