Sparenberg’s lifting surface theory for ship screws was programmed for the digital computer X 1 of the Netherlands Ship Model Basin. The results of systematic calculations for symmetric blades and pressure distributions can be interpreted as “lifting line to lifting surface correction” factors. These factors were plotted in a diagram for different pitch ratios, numbers of blades, blade area ratios and three types of radial load distributions.

    Also the effect of skew back and asymmetric chordwise pressure distributions has been considered.
