=== Generator choice ===
Normally, any DC generator can be used if the design of the nacelle is adapted. It has to be kept in mind that the nominal rotational speed of the set of blades and his nominal torque must remain lower than those of the generator. Indeed, if the rotational speed exceed its maximum value, it may cause dommages to the generator. If the torque exceed the maximum one, it will be impossible to brake the wind turbine and will cause the destrution of the generator. The designed rotational speed is fixed by the tip speed ratio for the nominal wind speed. The maximum torque is given by the matlab program for any type of set of blades.
=== Blades design ===
Thanks to our matlab program (available in file section), it is possible for everyone to create his own set of blades. Several parameters can be modified and put in arguments: profile type, radius of the blades, designed wind speed and designed wind speed ratio.
