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
Shown here is a rendering of a turbine prototype in the tow tank (minus the carriage)
