HYDRODYNAMIC FORCE ACTING ON A HIGH-SPEED CRAFT MOVING IN CALM WATER AND HEAD WAVES

The hydrodynamic forces acting on a model of a high-speed craft fixed by a load cell on a towing carriage were systematically measured for various trim angles, sinkages and forward speeds. These data are found useful to an understanding of the hydrodynamic characteristics of the shape of the high-speed craft. A simulation method for predicting the attitude and speed of the craft for a given thrust force by using the measured hydrodynamic forces is proposed. The simulation results demonstrate the effect that the height of the center of gravity and the angle of the propeller shaft have on the speed of the craft. Measurements of the wave exciting forces acting on the model craft moving in regular head waves were carried out. The results show a significant dependency of pitch exciting moment upon sinkage.
