Wind turbines

on 07 December 2015.

The use of wind energy fixated on one design - a windmill with wings. So windmills built by our ancestors.

The advantages of the screw (or more precisely, the wing) windmill allowed him to occupy a leading position among the devices that convert wind energy. But the high quality requirements of the wing, the complexity and high cost of production, poor strength characteristics of the entire design team, can not withstand storms and wind gusts pushed to find other solutions.


Furthermore, part of the wing surface is not operating - it is the supporting structure to resist wind loads.


Existing wind turbines use aerodynamic forces arising from the flow of air flow wing. Meanwhile, the power of the wind pressure on the surface can be many times greater than wind power.
