A laboratory study on the performance of corona thrusters as a function of the spatial arrangement of the emitting electrodes is presented. The setup consists in arrays of emitters and collectors with independently adjustable spacings. This thruster is tested in different benches, for output velocity and direct thrust measurements. The measured velocity is also used to determine thrust by momentum balance, comparing it with direct readings. Electric measurements complete the dataset. The parameter space consists of two different collector spacings and several emitter spacings, with fixed interelectrode gap and voltage. Within this space lies an optimal collector–emitter spacing ratio 2:1.

Abstract

A laboratory study on the performance of corona thrusters as a function of the spatial arrangement of the emitting electrodes is presented. The setup consists in arrays of emitters and collectors with independently adjustable spacings. This thruster is tested in different benches, for output velocity and direct thrust measurements. The measured velocity is also used to determine thrust by momentum balance, comparing it with direct readings. Electric measurements complete the dataset. The parameter space consists of two different collector spacings and several emitter spacings, with fixed interelectrode gap and voltage. Within this space lies an optimal collector–emitter spacing ratio 2:1.
