Analysis of Superconducting Electric Machines for Naval Ship Propulsion.
Abstract
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 is 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. The proposed superconducting motors and generators are modeled mathematically and simulated on a digital computer. Components for the motors and generators are designed to determine their individual characteristics and their interactions with other elements of the machines. Design analysis of the superconducting machines indicates they will be very small and lightweight.
