Applied ProductsThe Vertical Pneumatic Dynamo: Ryukyu-Wind soul

It will rotate when even breeze blows, regardless of the direction of the wind.
It is born from the technology of Japanese Aviation Universe Engineering

The small pneumatic dynamo complies with the working principles of our ancestors (that the wind on the earth will never be used up and is the inexhaustible resource; meanwhile, it is also the clean resource for the humans to span the future and to continue their prosperities.) We have realized manufacturing the windmill that can rotate even if its volume is small and in a light wind by applying the most advanced technological aviation engineering upon the blades of windmills.

What is the windmill of the pneumatic dynamo?

What is the windmill of the pneumatic dynamo?

1) The sort of windmills：Windmills can be divided into 2 big sorts, the “horizontal shaft type” and the “vertical shaft type” according to the direction of the rotation shaft of the windmill.
The new type of pneumatic dynamo of our company adopts the “vertical shaft type”

What is the windmill of the pneumatic dynamo?

2) The sort of the vertical shaft type windmills：Various kinds of principles of vertical type shaft type windmills have also been suggested and put in to practical use, and are also being improved all the time.
All the representative vertical shaft type can accept wind from all the directions and rotate.

3)The lift and the resistance：The lift and the resistance are the hydro forces that act on the mobile hydro objects.
“Gyro type” are using the lift.

    10) The blades of the “Ryukyu-Wind soul” can be protected by wearing a protection net from being destroyed.

The structure of the blades is
made in the same designing way as of the planes!!

The previous various kinds of windmills are utilizing either the “lift” or the “resistance” as its working principle.
But the blades of the newly developed “Ryukyu-Wind soul ” utilize both the “lift” and the “resistance”, namely it enhances the rotation efficiency by using the wind power for 2 times, so the pneumatic dynamo can even start working in a breeze. This technology has obtained its patent, and the patent number of the “Lave Stillnes wind” is It has obtained the Invention patent in Japan [patent 5731048th] and Registration of a design in Japan [Registration 1521963th・Registration1528705th]

The structure of the blades is<br>made in the same designing way as of the planes!!

  • 1) The picture on the right is a planform of the windmill.
  • 2) In the picture, the blades are being moved by the wind from the right side.
  • 3) The upper blade in the picture is rotating by the resistance.
  • 4) The lower blade in the picture is rotating by the lift.
  • 5) You can understand in this way that the principle is effectively utilizing the
    “lift ” and the “resistance” which are the energy power of the gyro type and
    savonius type of windmills at the same time.

The major difference between the conventional and the new type windmill(blade) called "Ryukyu-Wind soul" is that the conventional one is like of the airplane, closed in a bag-formed shape and the new type blade is opened in its rear part and curved to catch the breeze more efficiently. We also pay attention to the streamlined struts like the blade of airplane, which support the blade and the center shaft, making its rear part in such a way it can catch more easily the breeze, using effectively the lift power.

It’s revolution is controlled by the controller.
  • 1) Our original PLC control system regulates the windmill over-rotation and makes possible to generate continuously the electricity without stopping its rotation when strong winds are blowing in typhoon, etc. Furthermore, as a manual brake system is equipped, you can control the windmill absolutely sure in its inspection and do safely periodic machine maintenance at any time.
  • 2) As the rotation speed of this new type “Ryukyu-Wind soul ” windmill is low and the tip of blades are rounded, it is possible to minimize possible damage to animals or persons even when they touch it. Please note the windmill for disaster prevention is provided on an upper position of the pole (6.0m above the ground).

[ Environmental measures ]
Without noise and sympathetic vibration phenomenon.
  • 1) Air noise problem is almost null because its rotation speed is low (60~100rppm) except in Typhoon or other occasions when strong winds are blowing.
  • 2) This “Ryukyu-Wind soul ” windmill” is free from mechanical noise as a driving machine is only a generator.
  • 3) It is also free from mechanical vibration such as the resonance phenomena as the generation of turbulence is relatively low, because the driving machine is only a generator and its rotation speed is basically low and the rear parts of the blades are curved.
