Abstract:

The experimental results presented in this report describe the relative water elevation along the side of a model of the SL-7. Three relative motion components were measured and the results discussed. The components are the following one due to steady forward speed, one due to forced oscillation, and one due to incident waves. Capacitance wave probes were attached to the model at ten locations starting at the forward perpendicular and extending to mid-ships. The forced oscillation or radiation relative motion was measured for three different forward speeds. The reative motion associated with the incident wave was measured in both regular and irregular, transient waves. In all cases, the wave records were Fourier analyzed on line, between runs. The results are graphed as functions of wavelength to ship-length ratios and again as functions of longitudinal hull location. A number of repeatability tests and linearity checks were run. Author
