超電導電磁推進船の推進装置

抄録

The thrust force on electro-magnetic proplusion ship is generated by lorentz force due to interaction of the magnetic field and electric current in sea water, and an application of superconducting magnets are proposed in order to obtain heigher magnetic field. Initiated by Ship and Ocean Foundation in 1985, the research and development have been applied on superconducting coil, electrode, liquid helium refrigerator, hull form, etc. and a full scaleexperimental ship is now under construction, on which the thrusters of superconducting electromagnetic propulsion are installed. In this paper, the initial design of the ship, the principle of the propulsion, main technical points of the thruster and the propulsion system of the ship are described including their test results etc.
