This paper concerns the development of an impulse turbine with a self-pitch-controlled guide vane, which was proposed by the authors to be used as a wave power generator. In order to clarify the effects of the rotor blade profile and guide vane pitch/chord ratio on the characteristics of this turbine, experimental investigations were performed using small-scale equipment. These include three types of turbine blade rotors with different blade inlet angles γ and two types of guide vanes, that is, splitter type and monovane type. The results show that a high efficiency impulse turbine can be achieved for rotor blade profile with γ=60°. It is also found that, in this case, the optimum pitch/chord ratio of the guide vane (S_g/l_g) is about 0.8 for the splitter type, and S_g/l_g<0.65 for the monovane type. Furthermore, the effects of the nozzle setting angle and diffuser setting angle on the turbine characteristics have been clarified.
