500 kW hybrid propulsion system
A demonstrator of a hybrid-electric propulsion system for aviation based on HTS technology was developed with the financial support of the Advanced Research Foundation. Under this project, SuperOx developed and tested a number of HTS electric motor demonstrators for 50-500 kW power range. Achieving low AC losses in HTS coils, SuperOx made a real breakthrough in this project and demonstrated the reliability of HTS operation in a complex engineering device. In 2020, the operation of the HTS electric motor powered by lithium battery was demonstrated for the first time. Further cryogenic elements of the hybrid system were developed in frame of this project, including on-board SFCL, DC current bus, generator and commutation systems.
