The size and the weight of the tank is very crucial when designing a superconducting machine for airborne or marine applications (Bejan, 1976). There are also many factors that could affect the heat load of superconducting machines, alter their efficiencies, weight, cost, and also the specific mass of cryocoolers. .

The proposal by NASA to use high-temperature superconducting (HTS) generators and motors on future (~2035) aircraft for turboelectric propulsion imposes difficult requirements for cryocoolers. An overview on the history and development stages of using cryocoolers for rotating machines on a larger scale is given by Stautner in Chap. 6 Cryocoolers for Superconducting Generators in Atrey M (ed.) Cryocoolers—Theory and Applications International Cryogenics Monograph Series Springer Publishing 2020. This chapter features an excursion to investigate how rotating heat transfer can be possible in a vacuum environment, which may lead to novel methods impacting other engineering modalities.

Significant effort is being applied globally to develop lightweight, highly efficient motors and generators for airplane applications. These machines employ a variety of architectures, with designers choosing between permanent or coil magnets for excitation, air-core or iron-core magnetic circuits, and copper, aluminums or superconducting windings.
