THRUST AND THRUST-TO-POWER RATIO IN ELECTROHYDRODYNAMIC PROPULSION ELECTRODE SYSTEMS

Abstract

Abstract: Dependences for the efficiency of ionocraft electrode system and the magnitude of the thrust were obtained for different polarity of the corona. The most effective mode of work lifters of the considered structures is achieved at low current. The increase of distance between the corona electrode and the collector gives the growth of thrust and thrust-to-power ratio up to some distance. In the subsequent distancing statistically significant increase of characteristics is not observed. It is advisable to use emitters with smaller diameter to reduce losses to the formation of the corona.
