Once again, if this is an old invention, then the freewaring copyright only means the picture itself... otherwise it's free for all to use.
After last posts I got some complaints, like the pictures being more artsy than useful, and the pictures being totally smudged up by one faulty process or other. Smudges were due to Bitmap Grafix software I use ( Photoshop Elements ) telling always faulty news about the image size and quality, when converting from .Tif to .jpg. The lack of numbers and such was due to my inexperience and the early stage of the Idea.
In this diagram I included the precise wing / blade shaping angles and shapes... and their proper angles to each other (Picture can be enlarged and curves matched to them).
Then I calculated all the angles and proportions visually (For example 45 degree angle gives this 50 % foreshortening in the vertical height of the mast and the both wings ).
For example, in this A4 sized ( should be printable ) wingspan is 12 cm (6 cm per wing) and the mast height is ( 12cm : 5 = 2,4cm = 1x. 2,4cm X 4 = 9,6cm = lenght of the mast ) 9,6 cm. Towards the viewer, and also the direction of the wind, it seems to be 4,8cm due to it's diagonal 45 degree angle ( which causes that 50% foreshortening ).
Thus, when these proportions and angles are followed, the result should always be the shape below ( Though, with tight just untreated sail and this amount of curves, it will be more pointy than round, like bat wings, and a bit less fx. ) Using other wing materials, or 2x more of curves ( the height of the mast stays same, regardless ) should eliminate that... while possibly adding some weight.
The angles within the curves were calculated by the 45 angle of the whole apparatus and their "changing" profile towards the wind. Thus I came up with the steepest (uppermost) curve. Next one is 75% of it's "depth", thus properly aligning it's angles, next is 50% and the next is 25% and the bottom "curve" is always meant to be a straight stick. To make extra curves, take the top curve ( Which I call the Basic Curve ) and flatten it accordingly ( for example, extra curve between the Basic Top Curve and the next curve in the diagram... would be Basic Curve x 77,25 % in it's angle steepness. ( basically 90 degrees from the Basic top curve means 50% flattening of the curves... can be counted from that too... though here it has to be remembered that the virtual line, from exact center to the outer tip of the curve to be used, not the attachement point in the mast, as these change somewhat much depending on the actual curvature of each layer ). In other words, a thing that's not too hard to think or do in diagrams... but at least for me it's kind of gibberish to try to explain it precisely in the words. All this degree and % stuff can possibly be easier grasped by staring at the picture, than listening to me trying to explain it in math / verbal terms.
I planned versions with funnel shapes, broader flatter curves, etc. None of them seem viable, so from this diagram I eliminated all hints and musings to such shapes... I also planned nice wood / rope bearings to use where metal is not available... but surprise surprise, that seems slightly highly prone to catch fires constantly, so no more references to that shall be made. Ever.
Here, just for confusion's sake, is earlier version with some serious flaws, but with possibly somewhat workable mounting for the whole thing. (Wheels and their pathway is optional idea, possibly unneccessary in smaller versions). So notice only the mounting here. And also the neato wind-energy logo I sketched to it.
For extreme experimenting, One windyoni could be placed upside down, on a different but diagonal mounting, on a hilltop, so that the wind would enter the wings diagonally from "below". The point would (not be to make the wind catch the colourful whirling thingy and hurl it somewhere where it could do harm by falling on people and stuff) be to get increased efficiency from ground effect as the air gets packed between ground and the wingtips. Sounds less safe, though.
And so on. Next time, something else ?
