Experimental Determination of Wave Resistance of a Ship Model from Lateral Wave-Slope Measurements

摘要

A new method of determining ship model wave resistance from the wave pattern generated during a test in a model tank is outlined. This method is based on a Fourier analysis of lateral wave-slope data taken on a longitudinal cut parallel to the model path. Results of an exploratory test series are given and compared with previous results using a different method. The comparison is very encouraging and indicates that a new technique has been established which has many beneficial features, including potential application in full-scale research. Details of an electrical wave-slope measuring probe for use in the model tank are included in an appendix. (Author)
