Abstract

Abstract

To produce a stealth control technology for the static electric field of a ship with current compensation based on the control parameter (i.e., the ratio of the compensation current to the shaft current), this study analyzes variation trends in the underwater electric field and the optimal value of . Specifically, the study employs boundary element simulation software to assess a ship with different degrees of coating damage and different coating damage positions. Results show that the optimal value of gradually increases with the rate of coating damage. In addition, damage localized near the propeller affects the optimal value of , unlike that in the middle anterior of the hull. The effect of propeller rotational velocity on the optimal value of is also studied based on a scaled ship model experiment, with results showing that the optimal value of is not affected by the rotational velocity. Results also show that the maximum suppression ratios of the underwater electric field are different under different rotational velocities.
