A wind generator mainly consists of:

    1. Rotor
    1. Stator
    1. Hub and support
    1. Pole
    1. Blades

In the end, the wind generator appeared as shown in the images below:

The blades have a diameter of 3m, and the material used was fir (preferably pine).
The anemometer, shown in the images, was made from a bicycle axle to which three arms (made of electrode wire) were mounted at \(120^o\), and at the ends of the arms, plastic cups from "kinder eggs" were attached. A cyclometer (a speed indicator for bicycles) was used as a detection and indication device.

Operation on a calm day
Operation on a windy day

In strong winds (storms), it is important to protect the wind generator, especially the blades. In the videos above, on a windy day, "furling" is observed, where the entire assembly folds (for example, at the one-minute mark in the film) and assumes a position of minimal resistance to the wind flow.
To fold the entire assembly, it is necessary to mount the generator and tail with an offset (distance) from the central pivot axis, and additionally, the tail must be movable, achieved using a hinge type mount (pipe within a pipe).
The fact that the blades, in the video above, appear to spin forward, backward, stay still, or bend are optical illusions; in reality, they have a single direction of movement.
