profil de pale

CONT: The blade profile describes the shape you would see if you were to take a slice through the blade. It has a profound effect on the behaviour of the blade. There are a large number of standard profiles in use, described by names such as ""NACA4412"" which indicate the shape family and proportions of the blade.

CONT: ...as forças de sustentação e de araste no perfil da pá resultam em momento e rotação, girando o eixo do rotor e acionando, assim, o gerador, transformandoa energia cinética do vento em energia elétrica.
