The wave Devouring Propulsion System (WDPS) is one of devices which converts the wave energy directly into thrust. The system consists of hull and underwater foil. The damping force generated by the foil expects hull motion reduction in waves. Moreover, resistance increases in waves reduced and the foil thrust can use in waves. The new WDPS model with two foils was designed and tested in wave tank. The characteristics of the WDPS in the directional waves were studied. From these experiments, the advancement speed in beam sea condition becomes faster than head sea condition. From these results, widely applicability of WDPS even in the directional waves proved.

吞波推进系统是将波浪能直接转化为推力的装置之一。该系统由船体和水下翼组成。由翼片产生的阻尼力预期船体在波浪中的运动减小。另外，在波浪中阻力增大，减小，可以在波浪中使用翼片推力。设计了一种新型的双翼WDPS模型，并在波浪水槽中进行了试验。研究了定向波作用下WDPS的特性。从这些实验中，横浪条件下的前进速度变得比逆风条件下的更快。从这些结果中，WDPS的广泛适用性，即使在方向波证明。
