<p><P>PROBLEM TO BE SOLVED: To improve the strength or the like of an intersection of a main wing with a support wing of a vertical shaft wind and water turbine. <P>SOLUTION: The main wings 3 disposed around the axis and support wings 4 to connect the axial side to the main wings are integrated with each other by lightweight fiber of high strength such as glass fiber and carbon fiber. The main wings 3 are symmetric or asymmetric in section, and the support wings 4 are symmetric in section. Alternatively, the upper support wings 4 may be asymmetric in section, and the lower support wings 4 may be vertically line- symmetric to the upper support wings 4. A chevron part for noise control may be formed on an end of the main wing 4. A main wing forming die and a support wing forming die are formed of plastic, and intersected with each other. Both forming dies are covered by one bag-shaped lightweight fibrous cloth of high strength formed of such as glass fiber and carbon fiber. The bag-shaped fibrous cloth is tightly fitted to an outer surface of both forming dies to form a hard outer skin of a plurality of layers of fibrous cloths. Loosened parts of the fibrous cloths are pressed into plastic foam at an intersection or the like of the main wing forming die with the support wing forming die. <P>COPYRIGHT: (C)2003,JPO</p> |
