Research Abstract

This study investigated the application of pitch-controllable blades to a vertical axis marine turbine in order to be comparable to a horizontal axis marine turbine with high performance. The study developed a turbine model with variable-pitch mechanism and conducted model experiments in uniform flow in order to measure the turbine power. The net performance which was actual turbine power of the model was about 15% despite large mechanical friction. A Darrieus type without the pitch control was unable to rotate absolutely. The gross efficiency of the model taken from the forced rotation test was above 55% and it is huge efficiency.
