Modelowanie i wyznaczanie charakterystyk mocy układu napędowego statku wypornościowego ze śrubą o stałym skoku

The paper characterized the problem of finding propulsion characteristics of the propulsion system with a fixed pitch propeller. For this objective, statistical methods and the physical aspects of the construction of adequate models characteristics were used. Test results of propulsion system of vessel MS Garnuszewski were used for models verification. In total, five statistically comparable models of torque characteristics were developed, of which three models produce consistent results of tethered torque characteristics, obtained by extrapolation. It has been shown that the other characteristics: power characteristics, characteristics of specific energy consumption per nautical mile should be determined with definitional formulas after determining torque characteristics. Put attention to the need for analysis of deviations of measurement points on the model and the removal of excessive deflecting points.
