The present invention relates to a blast wing with maximized collection and discharge efficiency, and a configuration of the same is to form more than two wings at an equivalent angle interval around the center. In a blast wing which absorbs and discharges fresh air by being rotated by receiving external power, the blast wing of the present invention comprises: a vortex wing which is formed at an end of each wing constituting the blast wing, has a board shape, stands upright, and induces vortex of ambient air while rotating together with the wing; and a shielding wing which is formed at an end of each wing constituting the blast wing, has a board shape, stands upright, and prevents air absorbed by the blast wing from flowing into the vortex wing while rotating together with the wing by being located orthogonally to the vortex wing. The blast wing can absorb a large amount of air efficiently since the blast wing absorbs the ambient air forcibly by absorbing force of the blast wing under the state that the vortex is formed around the blast wing through the vortex wing rotating together with the blast wing; and has the effect of maximizing absorption efficiency of the blast wing by preventing the air absorbed by the absorption force of the blast wing from being distributed toward the vortex through the shielding wing rotating together with the blast wing. |
