A study on aerodynamic improvement of a multi-sailed ship toward a zero-emission wind driven vessel

本研究以实现零排放风力船舶为目标，研究了几种翼段呈直线排列的硬帆的气动特性，并开发了提高其性能的技术。通过数值模拟和风洞测量，研究了硬翼平排风帆间的相互作用对风推力性能的影响。在此基础上，提出了一种抑制推力下降、提高风帆性能的方法。此外，还建立了风力船舶的能量预测程序，并将其应用于海上航行中风帆性能的评估。

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.
