Initial strength of electric field of corona discharge with small interelectrode gaps in EHD converters

This paper continues the description commenced of generalized results of the research work [1-9] of the method of electrogas- and electro-hydrodynamic conversion of electric signals to pneumatic (hydraulic) signals and vice versa using corona discharge for the control of gas and liquid drops, volumes and flows of working media in electropneumohydraulic systems. Obtained is a formula for the initial strength of electric field generated by corona discharges in gases E_c with small inter-electrode gaps, which is in good agreement (as contrasted with the well-known formulae) with experimental results.
