Maximizing Performance of Aquantis Ocean Current Turbine
The Aquantis ocean current turbine utilizes innovative design approaches to maximize performance by focusing on vertical CG and CB separation, wake minimization, and structural efficiency. The transverse structure, made of 6061 aluminum pipes and optimized oval tubes, plays a crucial role in the turbine's overall functionality. This confidential model configuration aims to enhance renewable energy generation from marine currents effectively and sustainably.

THE AQUANTIS OCEAN-CURRENT TURBINE RENEWABLE ENERGY FROM MARINE CURRENTS C-Plane Tow Tank Model Configuration September 26, 2013 Henry Swales Ole Kils Company Confidential and Proprietary Company Confidential and Proprietary
Design Drivers Goals & Approaches: 1. Maximize vertical separation of CG & CB Place Structural Mass Low Keep wake out of alignment with rotor radial directions Place Buoyancy High 2. Minimize wake into the rotor - with and without fairings Concentrate upstream structures within 25% blade span where possible Move structural members as far forward as possible Maximize wake recovery Move CG forward to align with CB eliminate tail cone 3. Connect all moorings & cables to transverse structure Isolate loads measurements at nacelle connection 4. Provide independent adjustability of CG and CB locations without impacting net buoyancy 5. Minimize structural mass of buoyant elements Cylindrical pressure vessels have more crush resistance than flat fairings (less ribs & structural material required) Company Confidential and Proprietary
