Abstract


A flapping-type generator extracts power from tide induced vertical or swing motion of a hydrofoil or hydroplane submerged in water. When a nose-up pitch angle is prescribed for the hydroplane, it moves upward creating an upstroke of the flapping arm and vice versa for nose-down pitch. These up and down motion are then converted into a continuous rotary motion of an output shaft by a transmission system. In this study, we introduce the design and prototype implementation of a flappingtype tidal energy harvester including details on the design of the hydroplane, transmission, dynamic model, pitch control system, and its preliminary tests.
