In the case of an underwater, water robot navigating propulsion force and with other energy such as wind power, there is a problem that the thruster becomes a resistance at the time of navigation and the speed decreases. In this research, in order to solve such a problem, we proposed a new thruster. It is a new cylindrical thruster that uses flexible blades that cause the blade to peel off and generate propulsion force during rotation and not peel off and not resist when not rotating. In this research, we investigated changes in propulsion force and efficiency by using flexible blade mounting angle and rotational speed as parameters. As a result, the propulsion force was related to the shape of the blade due to the interaction between the elastic force of the blade and the drag. The shape of the blade was found to be related to the rotational speed and the mounting angle of the blade.
