The box-like structure is hermetically sealed, and will provide buoyancy, allowing the turbine to float in the water.
The flotation end cap has not been attached to this end.
The four rings at the corners of the frames will be used to tow the unit through the water at carefully regulated speeds, simulating the performance of the turbine when fixed in position in a watercourse flowing at those same speeds. The data will be used for further power optimization.
Temporary struts and cords hold some of the Flipwing blades up or open to show how they will move in position when in a water current. The middle and bottom blades are shown flipped open.
Tow tests are scheduled for this week.
More video of various turbine tests can be found on the Hydrovolts YouTube channel.
