A lot of attention has been paid to the drag-type vertical axis wind turbine （DTVAWT） due to its simple structure, good self-starting performance, low noise, wear resistance and other advantages. Many researchers also inte- grated the DTVAWT with the residential and commercial buildings for energy production. The blade profile of drag type vertical axis wind turbine is an important design factor affecting its performance. The suitable blade profile cannot only increase the power coefficient of the DTVAWTs, but also improve the aerodynamic characteristics of the wind turbine. In order to provide some reference for the optimization design of the blade profile of the DTVAWT, a comprehensive re- view about the current situation and development trend of the DTVAWT through the classification and comparison be- tween different types of blade profiles was conducted.
