A-C supplies for services in large aircraft — A British view

The paper deals with the increasing use of electricity as a source of power for operation of services in large transport aircraft. It outlines the advantages which are obtained from the use of medium-frequency a-c electricity and stresses the saving in weight which is obtainable from raising the present voltage (30 volts direct current) to around 200. Some suggestions are made in regard to form and layout for postwar installations in the case of both land airplanes and flying boats of the larger sizes.
