Abstract |
Ionic wind is an electro-hydrodynamic phenomenon that occurs when a corona discharge occurs between two asymmetric electrodes. Because the ionic wind does not need mechanical rotating parts unlike conventional motors and has a high energy efficiency to generate the wind, various researches have been conducted to apply ion wind to the fields of electrostatic precipitators, air purifiers, fluid pumps, cooling, propulsion. This study is for basic research of ion thruster and we investigated the characteristics of ionic wind distribution and Thrust according to hexagonal arrangement of corona electrodes. Experimental results show that the ionic wind distribution was strongest at the part where the corona electrode was disposed, and weakened at the part farther away, indicating a 'V' shape. The calculated thrust force using ionic wind distribution was weaker than the thrust force using corona current and the thrust force patterns were also completely different. |
