Experimental Study on a Method of Estimating the Wave-making Resistance of Submerged Body at Difterent Immersion from Tank Test Results

Abstract

We often need the estimation of the wave-making resistance of submarine at the immersion which does not correspond to the equivalent immersion of the model at tank test for various reasons such as the change of initial design, etc. The authors have sought for some simple methods suitable for design practice of modifying the wave-making resistance of a submerged boby obtained by tank tests according to changes of immersion, and propose a method in this paper. In order to examine whether this method can be applied in practice or not, they compared the values calculated by this method with test results. This method seems to give fairly good estimation of the wave-making resistance at the immersion which does not correspond with that of the model at the tank test.
