DETERMINISTIC PREDICTIONS OF THE MOTIONS OF A HYDROFOIL CRAFT IN IRREGULAR SEAS,
Abstract
The heave and pitch response time-histories of a fully wetted surface-piercing dihedral hydrofoil craft in irregular head seas was calculated from theoretical considerations, using the concept of the impulse response function. This function, which is the Fourier transform of the transfer function, was used in a convolution-type integral with the actual measured wave time-history to give a point-by-point deterministic prediction of the longitudinal motions. Comparison with experimental records indicates that the method yields a satisfactory approximation to the actual motion to a degree similar to that previously attained with surface ships and fully submerged bodies, and that it further substantiates the linearity of a hydrofoil craft-wave system.
