Popis:	The half-rotating impeller tidal turbine (HRITT) is a new type of vertical shaft tidal current turbine with lift and resistance performance. The experimental prototype and the experimental platform of the HRITT were designed and simulation experiments was carried out to analyze the energy extraction performance of the HRITT under various flow velocity and loads. The results of the experiment indicated that the platform was stable as well as reliable. The HRITT not only had good dynamic characteristics at low inflow velocity, but also had high efficiency that its maximum coefficient of energy extraction could increase to 45%. The flow velocity had little influence on the maximum efficiency of the HRITT.
