It is hardly damaged;Interior flabellum and outer flabellum are all made of the symmetrical structure of rule, and spin stabilization can generate the wind of uniform stabilization
Source.
Wind speed inductor and air quantity induction controller are set, wind speed it is smaller, without departing from limit value in the case of, interior wing
Leaf rotates power generation under the action of the forces of the wind, and outer flabellum does not start at this time, and flabellum in guiding of keeping watch makes interior flabellum than individual flabellum
Contact more wind, rotating speed faster;When wind speed exceeds limit value, outer flabellum starts to reversely rotate under the action of the wind, makes coaxial
Interior flabellum obtains the distinguished and admirable of superposition, and the covering of the fan outer rim linear velocity for making interior flabellum faster, improves the working efficiency of interior flabellum covering of the fan;Together
When the rotation of interior flabellum formation the outer flabellum of distinguished and admirable drive blade, inside and outside flabellum mutually drives, and generates double drive superposition effect
It answers.
Interior flabellum, outer flabellum material use fiberglass or carbon fiber, intensity high, light-weight.
Be in series with multiple flabellums between upper beam and bottom end rail, multiple flabellums can be installed on a holder, reduce at
This, improves generating efficiency.
