The present work intends to compare the propulsion force developed in anasymmetric capacitor, according to the number of positive ion sources used. Theion source is a corona wire, which generates a positive corona discharge innitrogen gas directed towards the ground electrode. We are going to apply theknown theory of electrohydrodynamics (EHD) and electrostatics in order tocompute all hydrodynamic and electrostatic forces that act on the consideredgeometry in an attempt to provide a physical insight on the force mechanismthat acts on each asymmetrical capacitor, and also to compare propulsionefficiencies.

Study on the influence that the number of positive ion sources has in the propulsion efficiency of an asymmetric capacitor in nitrogen gas
