Project Title:
MANAAGEMENT OF AC LOSSES IN HIGH TEMPERATURE SUPERCONDUCTING MAGNETIC LEVITATION AND PROPULSION COILS FOR LOW COST EXPENDABLE LAUNCH VEHICLES
Technical Abstract:
It is proposed to develop innovative ac loss tolerant coils made of high temperature superconducting (HTS)
conductor for the purpose of providing magnetic levitation and/or propulsion for low cost expendable launch
vehicles. The critical factors determining the use of superconducting levitation/propulsion magnets and SMES
devices is the requirement for the coils to i) minimize and ii) tolerate the losses generated due to the alternating
currents and magnetic fields to which the coils are subjected. Due to their higher operating temperatures and
the inherently higher heat capacity at these temperatures, the HTS materials are naturally more stable with
respect to these losses. HTS materials will lead to innovative designs which take advantage of the inherent
stability of the conductor, leading to more aggressive designs not possible for conventional (LTS)
superconductors.
Potential Commercial Applications:
HTS MagLev Coils,
SMES,
Motor/generator coils
