| Abstract |
In this paper, a study on the design feasibility of superconducting electric machine using HTS(High Temperature Superconducting) wire for electric propulsion aircraft was carried out. NASA(National Aeronautics and Space Administration) is developing electric propulsion aircraft and electric machine for electric propulsion aircraft and aims at 41.4kW/kg specific power by 2035. Based on research trends, this paper proceeds with the design of superconducting electric machine using fully air-cored superconducting field coil to achieve high power density. Electromagnetic design was performed for fully air-cored machine. Also, the superconducting field magnet and armature rotor design were performed to satisfy the generator requirements. The analysis result confirmed that the design target 10MW output was satisfied. The results of this study can be applied to the design and research of superconducting electric machine for electric propulsion aircraft |
