Other than Size and surface area, what makes a blade design for a wind turbine Efficientnt?
So i am making a wind turbine, and i know that the more blades more surface area would make it more efficient, but what aspect in the design would make it most efficient , because i want to compare different designs and come up with a central rule for blade efficiency, Can anyone help?
The shape or curve of the blade is also important since you want to minimize turbulence and maximize the amount of the wind velocity that is converted to force on the blade. You really need to find information on the design of aircraft propellers. This is not a question that can be easily answered here.

Hi! A small wind turbine for your house is a great investment and if you do it right you will laugh at your energy bill...
