This paper presents a review on the performance of Helical Darrieus Vertical Axis Wind Turbine (VAWT). It is known that torque delivered by vertical-axis wind turbines with either straight or conventional blades to their shaft fluctuates throughout 360° azimuthal angle. In contrast, a rotor with helically twisted blades delivers a relatively steady torque to the shaft. Over the years, numerous adaptations for this device were proposed in order to improve the self starting ability of turbine in urban area. Low noise level, rugged design, minimum maintenance, good performance in complex winds, safe operation in the urban environment and esthetic appearance are some advantages of using this type of machine. The aim of present article is to gather relevant information about Helical Darrieus VAWT, bringing a discussion about their performance. It is intended to provide useful knowledge for future studies.
