Problem: A method for a reduced frictional resistance ship for further reducing frictional resistance is provided. The solution is that the roll and pitch change greatly according to the change of climate, however, when limited to extremely short time, the roll and pitch repeat in almost the same or similar pattern. Therefore, if the previous roll and pitch mode is understood, the subsequent mode can also be predicted. This is similar to the vertical position change pattern of the microbubble generating unit calculated from the roll and pitch angles. Furthermore, the vertical position change is also different according to the mounting position of each micro-bubble generating unit, so that the present invention measures the vertical position change of each micro-bubble generating unit while predicting the current time and subsequent vertical position change. The predicted vertical position change is compared with the waterline height, and at the same time, the time when the microbubble generating unit below the sea surface will be above the sea surface or the time when the microbubble generating unit above the sea surface will be below the sea surface will be predicted, and at this time, the on/off valve 8 is switched.
问题:提供一种用于进一步减小摩擦阻力的减小的摩擦阻力的船的方法。解决方案:根据气候的变化等横摇和纵摇变化很大,然而,当限制在极短的时间内,横摇和纵摇以几乎相同或相似的模式重复。因此,如果理解了前一次横摇和纵摇的模式,也可以预测随后的模式。这类似于从横摇和纵摇角度计算的微小气泡产生单元的垂直位置变化模式。此外,垂直位置变化也根据每个微小气泡产生单元的安装位置而不同,因此本发明测量每个微小气泡产生单元的垂直位置变化,同时也预测当前时间和之后的垂直位置变化。将预测的垂直位置变化与吃水线高度进行比较,同时预测海面下的微小气泡产生单元将在海面上的时间或海面上的微小气泡产生单元将在海面下的时间,并在此时切换开/关阀8。
