A method for making a propulsion related characteristic of a free ship model similar to the real ship and the propeller related characteristic of the free running model ship. A real ship similarity device.
A method for making a propulsion related characteristic of a free ship model similar to the real ship and the propeller related characteristic of the free running model ship. A real ship similarity device.
PROBLEM TO BE SOLVED: To make propeller related characteristics of a free-running model ship similar to those of an actual ship.SOLUTION: On the basis of basic performance estimation of an actual ship, ship speed which varies under external force of a free-running model ship is measured and on the basis of the measured ship speed, propeller rotation frequency of the free-running model ship and output of auxiliary thrust means are controlled, thereby making propeller related characteristics of the free-running model ship under external force similar to those of the actual ship.SELECTED DRAWING: Figure 1
