Abstract :
A comprehensive computational feasibility study is presented for an outer-type electromagnetic thruster intended for ship propulsion. A thruster previously presented in the literature is modeled in a way to keep computer power needed in reasonable limits despite wide coverage of the efficiency estimates. For this purpose a two-dimensional approach is adopted. It is also shown how to generalize the results to similar vessels by means of scaling. Water salinity and magnetic flux density generated by the coils are included in the scaling model. The results are presented in a way to make comparison with the conventional ship propeller straightforward.
