An Integrated Wave Energy Recharging System for Autonomous Underwater Vehicles

Abstract

Abstract This work presents an energy harvesting system that can be integrated into most autonomous underwater vehicles (AUV), allowing it to operate for significantly longer periods of time, potentially indefinitely. This wave-power charging capability is achieved by integrating a retractable reaction structure that can be stowed against the body of the AUV when not in use and two rotary power takeoff elements housed inside the AUV. The technology is applicable to most AUV's; however, this study focuses on implementation within a Lockheed Martin ‘EMATT’ vehicle, a small 4 7/8" torpedo shaped AUV.
