Abstract : Numerous measurements were made of the resistance and reactance of aircraft BPVL conductors (of single or parallel connection of 2 to 5 conductors) during a current flow through the skin or through an insulated neutral line. In these measurements, the cross sections of conductors were varied from 1 - 16 sq mm, the height of their suspension above the skin - from 0 - 80 mm, the spacing between the conductors - from 0 - 45 mm, the conductors' length - from 1 - 2 m, and the metal skin structure was varied between that of an aileron and flap. Certain conclusions can be drawn from the above-established rules: (1) The magnitude of r and x in aircraft conductors is influenced by the type of aircraft skin, the height of conductors' suspension above the skin, and the type of conductors' run (single, forked, braided, etc.). (2) In designing of aircraft a-c networks, the magnitudes of resistance (r) and the reactance (x) should be determined by the following formula: r = r sub p + delta r; x = x sub p + delta x; where r sub p and x sub p represent the conductor's resistance and reactance proposed for an ideal conductivity of the skin; delta r and delta x represent the corrections of conductors' resistence, and reactance, which were computed experimentally for a given type of aircraft on the basis of the method cited above.
