Study of solid state remote control techniques as applied to the redesign of the electrical system in a large civil aircraft
Laura Jones · 1974
This Report describes how the electrical power distribution system of a large civil aircraft might be redesigned to employ remote power controllers, embodying solid state protection, in conjunction with solid state logic, to operate circuits remotely through lightweight signal wires. An assessment of the masses of a conventional and a remotely controlled system, based on a VC 10 installation in which it is assumed that the latest lightweight cables and switchgear are used indicates that the remotely controlled system would be about 90kg lighter. Additional saving might result from equipment specifically designed to be compatible with solid state remote control techniques. The effect on both systems of resiting the electrical compartment from the forward to a mid-aircraft position has been examined and it is concluded that a further saving of 36 kg would result with remote control. The redesigned system lends itself to, and has been arranged for, easy conversion to multiplexed data transmission. Although a multiplexed system has not been assessed, the mass of cables and fittings that would be replaced has
