摘要

As the Navy moves to the all-electric warship, superconducting materials will play a key enabling role. High temperature superconducting (HTS) motors and generators will enable extended range, high-efficiency, high-power density naval propulsion, and compact generators for weapons and ship systems. Compact mobile HTS generators also may provide portable/mobile power for littoral and expeditionary operation, naval air, and homeland security. The 'second generation' high-temperature superconductors (2G-HTS) based on yttrium- bariumcopper- oxide (YBCO) 'coated conductor' architectures are undergoing a processing technology breakthrough that will lead to large-scale manufacture by 2008. NRL is working with manufacturers to address key issues in the processing and performance of these conductors during this fast-paced stage of technology development. In particular, 2G-HTS process development is accelerated by fundamental understanding of the materials microstructures gained at NRL. Key goals include reduction of AC losses in the HTS motors and generators, as well as novel inductor designs for power electronics. Ensuring superior fatigue properties of the HTS materials compatible with the lifecycle of naval machinery is a key objective.
