Tidal Turbine Test ApparatusOBJECTIVE:

– To develop re-applicable Power Curves of scaled down models of Tidal Turbines.

Dynamometer for Drag Force on the Turbine

Apparatus Housing of instrumentation

APPARATUSAPPARATUS

• The apparatus will be bolted underneath the movable carriage to model tidal flow past the turbine in the 100’ Wave Tank.

Streamlined Keel

VISION: – To complete the ground work necessary to begin Tidal Turbine research for application as an alternative energy source in the State of Maine

Test Setup
