A paddle blade including a plurality of blades that allows fluid flow in between and along the plurality of blades. Each of the plurality of blades may have an airfoil shape and may be positioned parallel to each other. The plurality of blades may include a central diverter blade including two symmetrical, concave lateral faces. The concave lateral faces are configured to redirect, along arcuate paths, fluid flow from a direction approximately perpendicular to a front face of the paddle blade toward lateral sides of the paddle blade. The plurality of blades also includes a first and a second pair of blades positioned on opposite lateral sides of the central diverter blade, each arranged to at least partially overlap either one of the concave lateral faces of the central diverter blade or an adjacent blade of the first pair of blades respectively.
