Note:  EDITORIAL NOTE. Though this paper does not follow the general trend in development of Marine Screw propeller theory, the editors consider the author’s ideas to be original and worth of publication.
Abstract: In this paper a new method for designing the marine screw propeller is produced. It is based on combining the momentum and blade element theories, for calculating the radial patch distribution for a given load. The method covers both homogeneous flow and wake adapted propellers. Numerical examples arc given, and comparison with experimental results are shown. Theoretical aspects of screw propeller theory are discussed.
