The utility model relates to a vertical axis aerogenerator indicates neotype vertical axis symmetry formula aerogenerator's blade and wind wheel especially. The blade be that a cross -section is convex unsmooth simple blade, blade edge circumferencial direction card is in the draw -in groove of vertical axis 6, and the concave surface of blade installs towards the vertical axis, adopt 4 blades, constitute two S type aerogenerator. Go up the chuck 1 and the convex recess of facing (operation) of chuck 3 down, the both ends card makes vertical axis, upper and lower chuck and blade form a whole in these recesses about during rooting -in of blades, constitutes the wind wheel. Upper and lower chuck passes through the fix with screw and on the vertical axis, prevents that chuck and vertical axis from having relative rotation. Its characteristics lie in: the blade simple structure, simple to operate, and install along vertical axis circumferencial direction symmetry, during operation stability is high, wind wheel co
