Abstract: The wind loss denotes the energy lost due to the friction between the rarefied gas in the vacuum chamber and the energy storage flywheel rotating at a super high speed. The theoretical formula is deduced to draw the wind loss at the cylindrical side wall and the end side of the flywheel. The method of cut ting down the wind loss is presented according to the calculation and analysis on the wind loss. The calculated wind loss is accordance with the test result from the experiments on the flywheel energy storage system. The wind loss of the composites flywheel in test would be small enough to be ignored on the condition that the pressure is lower than 0.01 Pa in the vacuum chamber containing the flywheel.
Key words: Energy storage flywheel, Wind loss
