A COMPARISON OF CONTRAROTATING PROPELLERS WITH OTHER PROPULSION SYSTEMS

After brief comments on its place in a more general research program, the paper outlines the design changes necessary for the conversion of a container ship from a twin-screw power plant to a contrarotating power plant. The costs of the two ships are compared and an economic analysis of the differences in fuel costs is given. The results of a series of model tests comparing a contrarotating ship design with the original twin screw are given. Results from experiments with an overlapping propeller arrangement and single-screw tests are also included.
