I am building a small windmill at my house this summer. it will be a vertical shaft machnine with a airfoil shape similar top the Gossamar human powered aircraft. The yearly averaged wind speed is 17.5 kM/h. I am not sure of the the following:
1. Is there an optimum number of wings for the wind speed. I would like to produce some power at winds of 20 kM/h.
2. Is there a relationship between the wind speed and the raduis at which the airfoils are mounted.
3. Should the nose of the airfoil be tipped say ~5 deg. offset.
Kind regards.
