Rotawing: Journey to an Optimized Wing Design. Open Source keyhole winglet like Wing or blade

At it's most basic, the Rotawing is a lift producing design (can be spinning machine but does not have to be) with 2 elements.

The first element is 1, 2 (or more, preferably 2) crossectional wing(s) on a single or multiple implements, at any angle relative to eachother but preferably perpendicular or close to perpendicular to eachother on each implement.  What this means is on each "blade" there will be one, two, or more wing crossections.  These are not blades in the traditional sense though, but they could be.  If only one crossectional wing is used per implement, than the lift producing implement must be taller vertically than it is horizontally long, as this would be a standard wing/blade otherwise.  Also there can be multiple of these wings/blades along the diameter or area and they can be connected one or more together in any way desired and for any purpose desired.

The second element is any means to connect the wing to the central or midline hub.  This could be a blade that extends from the hub to the tip and provides lift in one direction, a string or multiple strings or cables, solid beam(s) or rod(s) or plate(s), a magnet, gravity generator, electrostatic attraction, or any other means that allows for any specific force(s) to be sustained.  This connection could also contain one or more of the crossectional wing(s).

In the above picture the top view may or may not have a lift producing crossection, and the side view also may or may not have a lift producing crossection.  In this invention, it could have one or the other or both.  Also if part of a rotating part, each blade can have slightly different designs in order to mimic bird flight, enhance lift, and enhance "grip" as seen in my other invention <here>.  As you can see an enhanced lift producing design can be used as seen in the above picture and also in my post <here>.

The reason for this design is to improve products such as propellers, fans, mixing devices, turbines, drills, or anything else that moves and/or spins through a medium.  This medium can be anything from solids, liquids, gasses, plasma, aether, or more exotic states of matter.  A wing is defined as a shape or set of properties (such as smoothness/roughness, van der waals or other forces) that provides lift or force or tension by virtue of simply moving relative to a medium of choice.

In a preferred embodiment as providing thrust or lift, a basic spinning design would have a wing shape in the side view of the machine. Or a common propeller design where each "blade tip" has a wing with a lift providing crossection perpendicular to the crossection of the blade it is attached to.  As seen below this blade tip would reduce the overall drag of the craft by "turning in" the drag lines towards the midline of the craft.  Or the wing tip could have lift in towards the midline of the craft.  While this will increase the overall drag of the craft, there will be less tension on the wing as the lift inwards toward the craft midline counter-acts some of the tension on the wing.

In a common propeller implementation the "blade tip" can be connected in any way to the end of the propeller blade.  See below picture for an example.

There can be a "hole" in the implement as well.  As seen below in a biplane/bipropeller example there are two lift producing blades (could be more) that are both attached separately to the "wing/bladetip".

This idea can also be used with a shroud and/or with the tips of each blade connected to one or more of their peers.  In the case of a shroud all points, one point, or a line of points of the tips can be nearest the shroud.  This line or points can be anywhere on the tip and can be any line pointing into the page on a top view, and/or a line pointing into the page on a side view of the tips.  These lines can be anywhere and can be designed to reduce drag, improve lift or force or thrust, or any other desire.  These "nearest points" to the shroud may be as close as possible to the shroud to reduce drag or any other use if desired.

These can be above the wing/blade only, below only, or both.  They can be canted, blended, raked, split tip, non-planar, or anything else.  They can be any design so long as they provide the stated function.

In conclusion, a new understanding of lift and drag has been reached.  Wing/blade tips have been designed that produce lift in a perpendicular direction and/or a parallel direction than is commonly done.  This has many benefits including reduced drag (including but not limited to wingtip vorticies) and improved lift or thrust.
