概要

In the previous reports, theoretical investigations were given for various aspects of wave devouring propulsion. The ideal wave devouring propulsion efficiency was discussed, and, when an oscillatory hydrofoil was used as a wave devouring propulsor, the importance of free surface effect and that of the optimization of foil motion were shown. In the present paper, the thrust generation through absorption of wave energy by a passive-type hydrofoil propulsor is verified experimentally by using a specially designed testing device, and the amount of the thrust is also mea,sured. Some theoretical studies are conducted to obtain the theoretical estimations for the free running or self-propulsion speed, foil motions and generated thrust etc. on the basis of Wu's theory for an unsteady hydrofoil in waves.
