Hello dear scientist,
I am looking for a precious help in order to size the mast of a wind turbine.
So I'm looking for the formula that allows, depending on the diameter of the blades, the number of blades, the incidence of the blades, the wind speed, the density of the air, the Betz formula, to know the force applied at the point extremum of my mast, by the wind.
From there I will dimension my mat for a two and three blade aerogenerator from 1,5 to 3 kW / h, the mat will be constructed as follows: 3 parts with a length of 3 meters nest one inside the other and guyed by 3 or 4 ribbon.
I am waiting for your help which will be very precious to me and therefore thank you in advance.
Sincerely,
Factor

Hello
A little reading before going into detail on your installation
http://users.swing.be/compagnons-eole/e ... /art17.htm
Remember that at 90Km / h (and this is not the maximum!), The pressure exerted on the rotor is 76 Kg (daN) per m2 of surface swept
Example
A rotor 3m in diameter has a surface of 7m2
The pressure at nominal speed (for example 10m / s) is 12 Kg / m2
The horizontal force on the top of the mast will be 84 Kg
It is therefore necessary to provide a safety device to stop or erase the wind turbine in strong winds. This is the limit value to choose
A+
