摘要：Based on characteristics of the half-rotating mechanism, a new type of vertical axis turbine with characteristic of lift-drag combination was proposed, which named the half-rotating impeller tidal turbine(HRITT). The turbine was composed of rotary mechanism, alignment mechanism and support mechanism. The mechanism design and manufacture of the HRITT were completed and underwater operation experiments were carried out to verify the rationality of mechanism design and its good self-starting performance. Through the hydrodynamic simulation of the impeller by Xflow, the changes of pressure and velocity around the blades in the flow field were analyzed, which proved the feasibility of the operation and energy-capturing characteristics of lift-drag combination of the HRITT.
