Abstract
An underwater flow turbine includes a gondola having an interior, a generator in the gondola interior, a rotatable hub connected to the gondola and configured to support a plurality of rotor blades, the rotatable hub being operatively connected to the generator, and an air handling device, such as a fan or an air filtration system, in the gondola and/or in the hub.
Claims18
An underwater flow turbine comprising:
- a gondola having an interior and a hermetically sealable access hatch, the access hatch providing fluid communication between the interior and an ambient atmosphere outside the gondola,
- a generator in the gondola interior,
- a rotatable hub connected to the gondola and configured to support a plurality of rotor blades, the rotatable hub being operatively connected to the generator, and
- an air handling device in the gondola,
- wherein the air handling device has an inlet in the interior and an outlet facing away from the inlet and into the access hatch, and
- wherein the air handling device is configured to direct a flow of air through the access hatch and into the ambient atmosphere.
