“…This composite aluminum conductor is not superconducting, but has an extremely low electrical resistance at liquid hydrogen temperatures, ~20 K [2]. A 600 kW exciter, also using the composite aluminum, constructed for the 40 MW generator weighed approximately 100 kg [3].…”

“…A main drawback of the composite aluminum conductor was the use of liquid hydrogen due to its limited availability in most applications. As such, "ceramic superconductors will generally be more practical to cool in similar applications when they achieve the necessary development status [2]." The first HTS ceramic superconductor to be made in practical lengths was bismuth strontium calcium copper oxide (BSCCO).…”

Abstract-Many future military systems will depend heavily on high electrical power input ranging from 100's kilowatts up to the multimegawatt level. These weapon systems include electromagnetic launch applications as well as electrically driven directed energy weapons (DEW), such as high power microwaves and solid state lasers. These power generation subsystems must often be packaged using limited space and strict weight limits on either ground mobile or airborne platforms. Superconducting generators made of high temperature superconductors (HTS) will enable megawatt-class airborne power systems that are lightweight and compact. Also discussed briefly are new advances in HTS conductors and refrigeration systems furthering the development of HTS power systems.
