The paper puts forward a new type of marine current energy conversion device, a flexible vane turbine. Its flexible vane is made of flexible material, which can deform to adapt to fluid. Thus the turbine can adjust the attack angle automatically to take full advantage of the lift effect and drag effect and produce as more power as possible, so it has unique hydrodynamic performances. Focusing on the power efficiency coefficient ( C_p ) , the authors studied its hydrodynamic characteristics and the affecting factors on them via a model test in a water tank. The results proved its characteristics and showed that, the shape of flexible vane and the structure of turbine rotor are the main factors affecting on its performance. Based on the analysis of the results, an optimal scheme of the flexible vane turbine having higher coefficient of power was proposed.
