Fabricando as Aletas do Exaustor Eolico (Building the Turbo Fan Blades)

pate 3 fabricação das Aletas do Exaustor Eolico (building the turbo fan blades) The blades are curved or straight and are designed to catch the wind and create a rotational force. The blades are often made of aluminum and have rolled edges to deflect water. The blades create the most effective support surface for winding and allow for a large twisting movement. The blade resistance thus ensures the most effective transmission of wind power to the rotary part of the turbine.
