In this research, toward the realization of a zero-emission wind driven vessel, aerodynamic characteristics of several hard sails with wing section arranged in line have been investigated and a technique for its performance increase has been developed. Numerical simulation and wind tunnel measurement of hard wing sails arranged in line have been conducted and an interaction between the sails, which decreases the wind thrust performance, has been clarified. Then, a technique to suppress the decrease of thrust and to improve sail’s performance has been proposed. Additionally, an energy prediction program of a wind driven vessel has been constructed and applied to evaluate the performance of the sails in ocean navigation.

在本研究中，为了实现零排放的风力驱动船，几个硬帆的翼型排列成一直线的空气动力学特性进行了研究，并已开发出一种技术，其性能的提高。对硬翼帆的顺列布置进行了数值模拟和风洞试验，阐明了帆片间的相互作用会降低硬翼帆的风推力性能。在此基础上，提出了一种抑制推力下降、改善帆面性能的方法。此外，还建立了一个风力船的能量预测程序，并应用于评估风帆在海洋航行中的性能。
