Fluidic turbine structure

A method for operation of a fluidic turbine capable of coupling with a drive shaft of a watercraft comprising:

• operating a fluidic turbine that rotates about a center axis of rotation, aligned to the drive shaft that contributes thrust through increasing lift and reducing drag, the fluidic turbine includes two or more curved fluidic elements that extend from a tip of the drive shaft that aligns to the center axis of rotation, to an opposing end at a radial position away from the center axis, and rotates about the center axis to contribute thrust;
• the two or more curved fluidic elements adapted to improve hydrodynamic flow along an axis parallel to the drive shaft, each curved fluidic element of the two or more curved fluidic elements configured to reduce turbulence based drag and increase lift based thrust;
• wherein in operation when coupled to the drive shaft of the ship, the lift based thrust is contributed when an incident fluid passes along a suction side of a curved fluidic element of the two or more curved fluidic elements and a pressure side of the curved fluidic element at different velocities, by applying time-dependent energy transfer (TDET) to condition the fluid flow at and upstream of an upstream end of the fluidic structure and accelerate the fluid flow along aligned trajectories at and downstream of a downstream end of the fluidic structure, reducing root vortex formation and vibrations;
• wherein a leading edge of the fluidic structure increases progressively in radius from an upstream end towards a downstream end;
• and
• wherein in operation, an incident fluid is channeled from the hub towards the radial position.
