COMPARISON OF SHIP-MOTION THEORY AND EXPERIMENT FOR DESTROYER WITH LARGE BULB

Experimental techniques for measuring pitch and heave motions for hull forms with large bulbous bows are investigated. It is found that free-running tests in regular small-amplitude waves give the most accurate results. A comparison of the pitch and heave amplitudes and phases obtained by the experiment and by the Korvin-Kroukovsky strip theory shows satisfactory agreement. It is concluded that with sufficiently accurate section representation, the strip theory can be used to predict head-seas motions not only for regular hull forms, but also for ships with bulbous bows and sonar arrays in small-amplitude waves.
