Abstract
More electrically driven aircrafts with electric propulsion systems are supposed to require 1-40 MW. In order to realize such heavily electrical aircrafts the development of lighter and more compact transmission cable systems is indispensable. We compared metal cables and superconducting cables, and found that DC superconducting cables are lighter and more compact than metal cables at voltages as high as ±6 kV.

More electrically driven aircrafts with electric propulsion systems are supposed to require 1-40 MW.In order to realize such heavily electrical aircrafts, in addition to the development of higher voltage electrical systems with motors and generators with much higher power densities than those at present, compatible with low atmospheric pressure at a high altitude, the development of lighter and more compact transmission cable systems is indispensable
Applied Superconductivity Constellations of Tsukuba (ASCOT) is studying superconducting cables for aircrafts, and in this paper we present the results of our feasibility study on superconducting cables for aircrafts
