Abstract: Straight-bladed vertical axis wind turbine(SB-VAWT) is typical representative of lift type vertical axis wind turbine at present. It has been received more and more attentions in small and medium scale wind energy utilization field due to the advantages of wind direction independence, simple structure, and unique shape. However, there are still some problems need to be studied because of its complex aerodynamic characteristics and relatively short studied time. The SB-VAWT has a broad development space. In this paper, the researches on aerodynamic characteristics of the SB-VAWT were discussed. Firstly, the brief history of the VAWT and its research status were reviewed. Then, we introduced the main principle, aerodynamic characteristics analysis theory, and common research methods. Especially, the research progress was analysed and summarized on how to improve its starting performance at low wind speed and aerodynamic output characteristics at high rotational speed. The future research trend was also prospected.
