Multi-Domain Modeling for High Temperature Superconducting Components for the CHEETA Hybrid Propulsion Power System

As the aviation industry focuses on increasing the sustainability of its technologies, fully electrified propulsion concepts are further explored and developed. One particular area of interest is in the development of hybrid propulsion aircraft using cryogenic cooling and components in the power system. This paper presents the modeling of the high temperature superconducting (HTS) transmission lines used in the power system of the Cryogenic High-Efficiency Electrical Technologies for Aircraft (CHEETA). These are novel components, so a mathematical model for both the electrical and thermal domains are provided in the paper. To this end, the development of these models allow for trade-off studies for different operating power capabilities, cooling mediums, and operational modes.
