Abstract

 A purpose of this study is to develop a Vertical Axis Type Marine Turbine with Variable-Pitch Blades which has high torque and power performance and being able to rotate in low fluid velocity condition. A Variable-Pitch system introduced in this study is developed with reference to Cycloidal propeller. Therefor it can be controlled mechanically for each rotation angle of pitch angle of the blade. In this study, start-up, torque and power efficiency performance of a Vertical Axis Type Marine Turbine with Variable-Pitch Blades are evaluated by using a model of turbine in tank experiment. In addition, the auther thought up a method of controlling blades which is adoptable fluid condition of Japanese ocean and estimated the expected value of energy acquisition this marine turbine in Bisan-Seto for one year. As the result of this study, the start-up, torque, power efficiency performance and the amount of acquired energy were improved by applying variable pitch blades. (Ideal-Variable-Pitch type)
