Superconducting electromagnets for large wind tunnel magnetic suspension and balance systems

Abstract

Abstract--This paper presents a new design study of a Magnetic Suspension and Balance System (MSBS) for airplane models in a large 8 ft x 8 ft wind tunnel. New developments in the design include: use of a superconducting solenoid as a model core instead of magnetized iron; combination of permanent magnet material in the model wings along with four race-track coils to produce the required roll torque; and mounting of all the magnets in an integral cold structure instead of in separate cryostats. Design of superconducting solenoid model cores and practical experience with a small-scale prototype are discussed.

Design, analysis, set‐up fabrication, control, and a novel analytical approach of a levitation prototype for a symmetric shaped object

“…Superconducting in axial bearings for active induction devices are further discussed by Nikolsky et al in [10] but point to point procedures of coil design and fully lab developed prototypes have not been discussed anywhere. Yang et al have also introduced development of force modelling instrument for EM system in [11]. But no set-up fabrication has been discussed in the above literatures.…”
