Variable Speed, Constant Frequency (VSCF) Electric Power Distribution Systems for Aircraft

Investigation of the problems associated with the design and installation of high frequency, electric power transmission lines in aircraft has resulted in a descriptive analysis which is presented in this paper. The effects of frequency, ground plane elevation, feeder configuration, wire bundle size, induction, and shielding on transmission line impedance are included. Electromagnetic interference is also considered, on the basis of experimental data, and is described in terms of the dynamic image of charge. Recent experimental data obtained at North American Aviation, Inc. supports the discussion throughout.
