PROPELLER-HULL INTERACTION AND PROPULSIVE EFFICIENCY

The economic operation of a ship depends on the propulsive efficiency, which is related to the following factors: 1. Choice of design parameters. 2. Propeller-hull interaction. 3. Propeller design revolutions. 4. Propeller efficiency. The propulsive efficiency values for a number of different ship types have been determined experimentally in the El Pardo Model Basin. The results are analysed in this paper, which includes comments on the various aspects of propeller-hull interaction for single-screw ships. An improved general formula for estimating the propulsive efficiency of single-screw ships is presented in Appendix 1. In Appendix 2, a new method used at El pardo for power estimates based on statistical information in the data bank, is introduced.
