<p><P>PROBLEM TO BE SOLVED: To obtain a structure mode capable of improving the efficiency of the rotor of a three blade type vertical shaft wind turbine device and converting the rotational energy into a different energy. <P>SOLUTION: In order to efficiently use an energy of wind in the vertical direction of a conventional three blade type vertical shaft wind turbine device, the vertical direction of a blade is curved so as to be squeezed, so that the flow of wind in the vertical direction is smooth and contributes to the rotational force of the wind turbine device. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
