リンク機構によるブレード迎角可変機構をもつ垂直軸風車の研究

抄録

There are two types of VAWT, drag type and lift type. Drag type starts up in the low wind velocity, however peripheral velocity does not exceed the wind velocity. As for the lift type, peripheral velocity exceeds the wind velocity, however it does not start up in the low wind velocity. A new blade section, Magatama, has been proposed. Magatama blades may have both advantages of drag and lift type. Most of VAWT are fixed pitch type. It cannot recover enough wind power energy. To recover more energy, the VAWT with linkage mechanism is proposed. In this study, the VAWT with linkage mechanism was produced. The blade section of the VAWT is the Magatama. Proper blade setting angle was confirmed by numerical simulation.
