Design and verification of a small-scale lift-type vertical axis wind turbine composite blade

Abstract

In order to obtain the small lift style vertical axis wind turbine with excellent performances, this paper presented the technologies of design and manufacture of the composite blade with high lift coefficient. The manufacturing process was evaluated based on the dimensional accuracy of the blade. The structure of the composite blade was evaluated by means of finite element modeling (FEM) and the mechanical property. Moreover, the vibration property of the blade was studied by FEM, and the resonance of the wind turbine assembled with the blade was investigated.
