SE3000 Fall AY15 Systems Engineering Colloquium

High Temperature Superconductivity Activities at NAVSSES

Jacob Kephart, Ph.D. Naval Surface Warfare Center Carderock Division Ship Systems Engineering Station Applied Superconductivity Group

Future power systems onboard Navy ships are required to be power dense as well as efficient to support the loads of electric propulsion, high powered radar, free electron lasers, rail guns, as well as other forms of high demand offensive and defensive capabilities. One technology area that appears to be particularly well suited to address some of the challenges of high efficiency and high power density is High Temperature Superconductors (HTS). This talk focuses on an overview of HTS including the limiting factors in its use. Commercial applications and viability will be touched upon followed by the challenges of using HTS technology in the Navy. The primary focus on the Naval HTS development is not specifically on the HTS material, but the use of the material while efficiently maintaining the cryogenic environment. Commonality of components that make up functionally different HTS systems has led the Navy into a developmental approach that allows for common cryogenic building blocks to be used as the foundation for multiple HTS systems.
