    • A loss reducing device of a rotary body capable of reducing a fluid resistance loss at a low cost while utilizing a conventional bearing technology by rotating the rotary body with high peripheral velocity in the atmosphere or in an environment near the atmosphere so as to increase the efficiency of an energy storage device such as a flywheel, comprising the rotatably supported and rotating rotary body, a covering rotary body having the same rotating axis as that of the rotary body, rotatably supported, and covering the rotary body installed on the outside of the rotary body, a plurality of covering rotary bodies having the same rotating axis as that of the rotary body and covering the outside of the loss reducing device installed overlappingly with each other, and a bearing means installed between the rotary body and the covering rotary body adjacent to the rotary body or the covering rotary bodies adjacent to each other, wherein the bearings of the covering rotary bodies covering the rotary body are arranged in series with the bearing of the rotary body, and hydrogen gas or helium gas with a density smaller than that of air is filled into a container to further reduce a wind loss.
    • 一种旋转体的减少损失装置,能够以低成本降低流体阻力损失,同时利用传统的轴承技术,通过在大气中或在大气附近的环境中以高圆周速度旋转旋转体,从而提高效率 包括可旋转地支撑和旋转的旋转体的能量存储装置,具有与旋转体相同的旋转轴的覆盖旋转体,可旋转地支撑,并且覆盖安装在旋转体的外侧的旋转体 多个覆盖旋转体,其具有与旋转体相同的旋转轴线并覆盖彼此重叠设置的减损装置的外侧;以及轴承装置,安装在旋转体和覆盖旋转体之间, 旋转体或覆盖旋转体彼此相邻,其中覆盖旋转体的轴承覆盖 旋转体与旋转体的轴承串联布置,并且将密度小于空气的氢气或氦气填充到容器中,以进一步减少风力损失。
