The present invention relates to a wind turbine, and in particular, the wings disposed around the rotary shaft is moved by the wind to transfer power to the rotary shaft and the structure of the blade is changed according to the wind strength to prevent damage to the wind turbine The present invention relates to a wing mobile wind turbine that can produce electricity effectively.

In general, the wind power generator is a device for generating the necessary power by using the force of the air flow that unlimitedly generated on the earth, and is formed to have at least one wing that rotates in response to the lift by the wind.

On the other hand, the wing of the wind power generator must have a function to generate lift even in the weak winds and must have a structure that can rotate smoothly without being damaged by strong winds. That is, the wing of the wind turbine is formed in a large area in order to generate a large lift even in the weak wind, and also in a small area in order not to be damaged in the strong wind. As such, the wings of the wind turbine had to satisfy two opposite conditions simultaneously.
