<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus of a load-variable self-propelling test capable of appropriately setting a relationship between the propeller rotating speed and a ship speed of a model ship in a self-propelling test performing not only a rectilinear propagation but also an oblique sailing and turning by an external force and hull rocking by the external force including wave, and in a self-propelling test capable of changing the propeller rotating speed on the way. <P>SOLUTION: In a method of self-propelling test using a self-propelled model ship 6, auxiliary thrust adding means 4 that is provided in tracking means 5 for tracking the model ship 6 and adds an auxiliary thrust to the ship model 6, is controlled according to a calculation result of auxiliary thrust calculation means 3 that calculates the auxiliary thrust based on the moving state of the model ship 6. The auxiliary thrust based on its moving state is thus added to the model ship 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
