<p>PROBLEM TO BE SOLVED: To eliminate some defects that almost of all practically used wind power generators are of a propeller type, only one wind power generator with several tens of thousands KW has not yet been developed and it is at most to set a goal on a wing length of 100 m and an output of ten thousand KW, and it has not yet been practically used due to its high cost.SOLUTION: Although a propeller type in the prior art shows a geometric defect, this invention can resolve some problems about strength and increased amount of mass because both ends and a central part of a straight wing can be directly connected to a central shaft. The straight wing shows a low self-driving force as well as a low component force in its rotating direction (lower capability of power generation). However, the straight wing resolves the problems by (1) increasing the component force in the rotating direction by setting a set angle of the straight wing to show 45° in respect to a radius direction, (2) supplementing the self-driving force by combining it with a drag type wing to make a hybrid system, and (3) making ultra multi-wings, forming various states of attack angle to increase the power generating force. The inventor disclosed a vertical shaft type power generator by assembling the lifting power type wing with the drag type wing. The inventor of the present invention has designed it that is applicable for practical usage by changing this vertical shaft into horizontal shaft to restrict construction expenditure even for a wing length of several hundreds meters and power output of several hundreds of thousands KW.</p> |
