As everybody in Lifter mailing list are well avare, the work on corona-discharged aircraft has moved from the stage of the demonstrating the basic ability to develop thrust to development of autonomously powered aircraft, which requires clear understanding of technical improvements needed to achieve the flight powered with on-board power supply. Recently developed by author engineering model of basic lifter  allowed to predict correctly thrust and voltage/current relation of all existing externally powered lifter models described in Jean-Louis Naudin's Lifter web-site. The natural next step is to derive relations combining such key engineering characteristics as power density of autonomous power supply and specific weight of wire/collector electrode stack with the lenght of electrode stack and distance between corona-wire and collector which would provide sufficient efficiency and power for self-propelled flight. This is the topic of this communication.

Theoretical background
Following equation describing thrust/current and curren/voltage relatioin of coron-discharge propelled device, derived by author in  based on voltage-current relation in electrostatic dust precipitators developed by Copperman (P. Cooperman, Theory for Space-Charge-Limited Current with Application to Electrical Precipitation, Trans. Amer. Inst. Elec. Eng. Part 1, vol. 79, pp. 47-50, 1960.) are used in derivation below.
