The invention is filled in the present invention relates to aerial wind power generation system such that, and to obtain an electric energy injured by the number of levitation tube, the generation of electric energy that the charger (1) by the wind of the wind passing through the wind tunnel and wire as it is injured hanging in the air by a holding wire 11 connected to the rotating means (10); And the tunnel member 22, with the wind tunnel 21, which wind passes in the horizontal direction, and the wind tunnel Wind rotor (23 230) which is rotated by wind passing through the 21, the total 23, the wind times a speed increasing means having a pivot axis (24) support means for supporting 25 and the rotation shaft 24, the large diameter gear (26a) and interlocking the small-diameter gear (26b) which is fixed to 26, wherein wind power means having receiving the rotational force from the small-diameter gear (26b) generator (27) to generate electric energy (20); The wind power generation means 20 to attach each to be fixed in the longitudinal direction of the tunnel member 22 to ensure that injury in the air and the direction to the upper air inlet 31 and the trailing side for introducing the air inside the wing (32) a is the so comprises a pair of levitation tube 30 having, respectively. Aerial wind power generation system. Aerial wind power equipment, outdoor power generator
