Propeller

A propeller for use with fluids, the propeller provided to propel an object or person or to move the fluid, the propeller comprising:

• a plurality of asymmetrical blades;
• a rotational axis;
• the plurality of blades extending outward from the rotational axis and disposed around the rotational axis;
• each blade of the plurality of blades forming a loop and having an intake portion, and exhaust portion and a tip portion extending radially outward from the rotational axis;
• the loop of each blade having an intake root and an exhaust root, and a gap between the intake root and the exhaust root;
• wherein the propeller has a configuration to generate non-axial lift and non-axial fluid flow and to redirect the non-axial fluid flow to axial fluid flow, wherein the configuration includes:
• throughout at least a portion of the tip portion of the blades of the plurality of blades before a 90 degree roll and toward the intake portion of the tip section, a distance (N) to a nose of a cross-section as measured perpendicularly from the rotational axis is greater than a distance (T) to a tail of the cross-section as measured perpendicularly from the rotational axis, wherein the cross-section is taken from a fore location view of the propeller along the rotational axis and perpendicularly to the rotational axis;
• and
• each blade of the plurality of blades further comprising 80% of the tip portion of the blades having a roll value of less than 90 degrees and N>T for the same 80% of the tip portion.
