A sail-type wind power plant using swinging sailblade for water lifting is presented. The working principle of the plant and the relation between the aerodynamic force and the drag of water lifting are discussed. The swinging of the sail blade and the frequency are investigated. The optimum mounting angle of sail blade and the power output of the plant are calculated.An example with a blade of area S=2m2, length of the swinging bar of l= 3m and rated wind speed V = 6m/s to show how the plant is calculated is given. The results obtained are; lifting force f = 279.4N, swing angle of swinging bar = 120% number of swing times per minute N=14, mean power=60W, wind power coefficient Cp= 0.23.It is shown that the plant investigated is suitable for use in areas where low waterhead and a rated wind speed of less than 6 m/s are available.
