Abstract:

A suitable manufacturing technology for bulk superconductors is crucial for their
use in aerospace power and propulsion applications. State-of-the-art processing of
bulk, high-temperature superconductors (HTSC) gives a brittle material with low current-carry
capacities; whereas, HTSC thin films show current densities exceeding 106 amps/cm2.
The innovation is to utilize a thin film deposition technique to fabricate the superconducting
component of a bulk conductor. This will be achieved by depositing high-quality BiSrCaCuO
films by metal-organic chemical vapor deposition on platinum-coated tungsten fibers.
The current carrying capacity of the superconducting layer should approach that achievable
in thin films and the mechanical properties of the composite fibers will be dominated
by the high strength of the tungsten core. In Phase II, continuous processing will
be developed and the resulting fibers used to fabricate a multifilament conductor
with electrical and mechanical properties suitable for aerospace applications.
