Aviation emissions create one of the serious problems related to climate change and environmental pollution. Zero emissions can be achieved by using all-electric aircraft. Superconducting electrical machine (SCEM) technologies are considered a more promising candidate compared to permanent magnet counterparts to meet the needs of aircraft propulsion. The needs include high specific power of the electrical machine, high-speed operation of the rotor, and high-frequency operation of the stator. The project is to find out the most suitable designs of SCEMs that meet such needs. In the project, innovative design methods for SCEMs are developed. New optimization methods and calculation models are explored for machine topologies, conductor materials, coil architectures, and various cryocooling methods. The design methods are partly experimentally validated. The project is a step forward toward zero-emission aviation, preparing electrical machine technologies for this demanding application.
