| Abstract: | According to the characteristics of motion of high speed craft in still water and waves, the fundamental hypotheses of longitudinal motion of the high speed craft in heading sea are presented; the longitudinal motion equation of the planning craft in heading sea is established, which includes the effects of the hydrodynamic lift and the hydrodynamic moment of the planning craft; a new theoretical method on longitudinal motion of the high speed craft in waves, i.e. planning method, is presented; and the theoretical prediction program is set up. The model experiments in waves are carried out. The calculated values of heave, pitch in different speeds, are compared with experimental values. The result shows that the planning method is suitable for the prediction of longitudinal motion of high speed craft in heading sea at the middle or high speed. |
