It is provided a method of manufacturing a propeller having a plurality of blades, each of the plurality of blades having an intake portion, an exhaust portion, and a tip portion extending from the intake portion to the exhaust portion, the method comprising: defining a plurality of parameter sections by selecting some of the parameters including skew angle, roll angle, rake, radius, pitch angle, vertical angle values defining a parameter section at the transition from the intake portion to the tip portion by parameters to cause the amount of non-axial lift in the tip portion to be greater than the axial lift in the tip portion defining parameter sections to include a roll value of 90 degrees in the tip portion and extrapolating between parameter sections to form smooth lines to form a blade configured to form a loop when attached to a hub.
