Introduction• Direct drive power generation at low flow velocities• Magnets engage with coils • Axial displacement is relative to drag on the rotors

Objectives

Design and construct a hydrokinetic turbine to utilize low velocity tidal currents for power generation.

VFG Wind Turbine:4.7m diameter

Approach• Water is 830 times denser than air

– Turbine blades will encounter higher forces• Model tested in tow tank • Demonstration model turbine to be deployed under

General Sullivan Bridge

Major Tasks• Stator Development

– Includes coils specified to generate a certain amount of electricity at certain frequency

• Rotor Design– Formed by turbine blade assembly– Turns magnetic ring assembly in generator

• Blade Selection– Shape, angle of attack & material

Major Tasks (cont.)• Water Proofing and Corrosion Resistance

– Salt water application– Component isolation from water

• Generator Actuation– Magnetic rotor– Fixed coils– Magnetic rotor can move axially

• Deployment Structure– Based from barge– Based from pier– Based from platform in Tow Tank
