BASIC STUDY OF SUPERCONDUCTING ELECTROMAGNETIC THRUST DRIVE

An electromagnetic thrust device consisting of a race-track type super-conducting magnet and a flat-plane electrode has been designed and built and its performance tested in a small model ship (SEMT-1). The main advantages of the design are: (a) The repulsive force acting on the parallel part of the super-conducting magnet is contained within a cryostat wall. (b) Fabrication of the magnet and cryostat is simple. (c) It provides for the most efficient use of liquid helium as cooling medium. The main problem to be encountered when the external electromagnetic thrust takes on the super-conducting magnet is the difficulty of obtaining the greatest efficiency from the magnetic field because of the necessity for a thermal insulating layer to keep the super-conducting magnet at a low temperature.
