As shown in FIG. 2, when the wind hits the once-through wind turbine from an arbitrary horizontal direction, the wind passes between the wind collecting plates 9 of the wind collecting unit 2 which is open in the main flow direction.
At this time, since the interval between the wind collecting plates 9 adjacent to each other is smaller in the inner peripheral portion than in the outer peripheral portion of the wind collecting portion 2, the wind passing through the wind collecting portion 2 is accelerated and enters the rotor rotation output portion 1. . Further, since the outer edge of each wind collecting plate 9 is curved in an arc shape, the wind is collected extremely efficiently and sent to the rotor rotation output unit 1.
The wind that has entered the rotor rotation output unit 1 hits each of the moving blades 6 and passes through the space between the moving blades 6 on the opposite side to the wind collecting unit 2 while rotating the rotor rotation output unit 1 around the rotation shaft 3. Here, since the outer edge of the rotor blade 6 of the rotor rotation output unit 1 is curved in an arc shape, the rotor rotation output unit 1 efficiently receives the wind and rotates. The wind escaping from the rotor rotation output unit 1 to the wind collection unit 2
In this case, the vehicle passes between the wind collecting plates 9 having gradually increasing intervals, while reducing the speed. In this way, power is generated by the generator 10 via the rotating shaft 3 by the momentum conversion between the wind and the rotor blades 6 of the rotor rotation output unit 1.

In addition, FIG. 4 also shows, for comparison, the measurement results in the case where a linear air collecting plate having no arc-shaped curved portion is used as the air collecting plate of the air collecting portion 2. As can be seen from FIG. 4, the output coefficient Cp and the torque coefficient Cq are greatly improved irrespective of the value of the tip peripheral speed ratio λ by curving the outer edge of the wind collecting plate 9 in an arc shape.
