A proposed ship propulsion system which incorporates
superconducting electric machines as the transmission
system between the prime mover and the propeller is
described. The propulsion system employs gas turbine
prime movers, synchronous generators and synchronous
motors with superconducting field windings, switch gear
with a cycloconverter, variable frequency, power controller
between the generators and the motors. The proposed
system in the DD963 destroyer, which has a gas turbine
propulsion system driving controllable pitch propellers
through reduction gears. The resulting ship is compared
with the original on the basis of weight and volume. A
smaller ship with an identical payload but a smaller propulsion
system is constructed to take advantage of the
weight and volume savings which are a result of using
superconducting electric machinery. The smaller ship is
compared with the original DD963 on the basis of weight,
volume, efficiency and cost ceiling for the superconducting
electric propulsion system.
