Design Approaches for the Supersonic Transport Electric Power System

This paper presents the results of a study program in which various approaches to the design of an a-c electric power system for a supersonic transport were considered. Transmission of power at higher than normal generated voltages, with assumed feeder lengths of both 100 feet and 180 feet, was evaluated to determine weight reductions to be expected and the effect on system losses. Both constant-speed, constant-frequency systems and variable-speed, constant-frequency type systems were considered. The study was based on a 160 kva system with four 40 kva channels.
