This paper deals with an experimental study of propulsion force characteristics of travelling-wave motion of a flexible plate modeled on the flexible caudal fin of fish. The flexible plate is attached at the trailing edge of an oscillating wing which are heaving and pitching around the leading edge of the oscillating wing, and the travelling-wave motion of the flexible plate is excited by the combination motion of the heaving and pitching motion of the wing. In the experiment, the mean propulsion force and side force generated by the travelling-wave motion of the flexible plate in stationary water is examined. As the result of the experiment, the effect of the travelling-wave motion of the flexible plate on the propulsion force characteristics is clarified with changing the length and thickness of the flexible plate.
