SELECTION OF OPTIMUM SPEED PERFORMANCE REGIME OF THE PROPULSION UNIT OF A RIVER VESSEL

Methods for selecting an optimum operating regime of a propulsion unit of river vessels are discussed. This work is investigated by a finding that a decrease of 3 percent in the speed of boats leads to a 20-50 percent increase in the fuel efficiency. The criterion for the speed is the rate of revolution of the propulsion unit. It is used to describe a simple method that determines the boat speed as a function of propulsion power and other parameters. A similar approach is taken in modernizing the method developed by G. Ye. Pavlenko (O regulirovanii rezhimov i avtomatizatsii sudovozhdeniya na rekakh. Izd-vo AN UkrSSR, 1961). A concrete example is worked out and the optimum number of revolutions depending on the river depth is given.
