Dynamic Performance of High-Temperature Superconducting Multi-Layer Spiral Cable for Airborne Transient Electromagnetic Transmitting Coil

High-temperature superconducting cables possess the advantages of relatively low weight per unit length, high current carrying capacity, and strong resistance to complex electromagnetic environments, which can meet the needs of the further development of exploration technologies. Superconducting flexible core cables have a small bendable radius, and the manufacturing processes of materials and supporting components are relatively simpler. In response to the requirements of mechanical strength and lightweight for aviation geological exploration systems, this paper proposes a topological structure of an electromagnetic emission coil based on lightweight high-temperature superconducting bundled cables. The critical current changes and AC losses when applied in electromagnetic emission conditions are calculated and studied.
