Re: Aerodynamically better leading edge

we didnt know what the f*** we were doing with kites 10 years ago. ... I can't tell you how important that statement by edt is !!!! :thumb: The sum total of ALL mans knowledge is doubling at a rate of every (1) year ; what we knew about kites 10 years ago , we got like ((10 X 2) times 10)) More kno...

Re: Aerodynamically better leading edge

... ... My guess is that a different tube shape won't offer any benefits. In the end you'll have the same netto l/d ratio. Not to mention a more difficult and probably weaker construction. That is your opinion ; i got a way different one. Would you want it any different as far as opinions go ? No w...

Re: Aerodynamically better leading edge

You can absolutely make the leading edge much more aerodynamic and add just a tiny bit more weight. First of all, like Peter suggests, you do want to retain the original tube, same size and everything. But like Billie mentioned you add additional structure. The key point is that you can make a shap...

Re: Aerodynamically better leading edge

Good question Kami ; wouldn't know, unless it was tried ?

I know for absolute sure ; it would create a Lot more lift, (with camber changing)
at a substantial amount LESS drag at speed, (so maybe it would be worth it / maybe Not) .
You would be targeting higher winds ; like 20 to 40-knots.

Re: Aerodynamically better leading edge

... See how the airfoil is nice and flat on the bottom surface, (behind the circle) i drew in ; i think a sharp angle L shape, where the air exits and goes rearward toward the back of the kite, instead of the round tube we have now, would create a LOT less drag on the bottom surface. ...would act a...

Re: Aerodynamically better leading edge

There is a better way : Google search inflatable SUP boards construction ; and you get something like this : http://www.supnorth.co/why-red-paddle-co/ Self explanatory, as to how this technology could be used !! :D We'd be using about as much of the airfoil on the LE , as where the #2 is located on...

Re: Aerodynamically better leading edge

... Meaning, stiffness is proportional to diameter cubed, so if you have the double stifness from two tubes, you can only decrease the diameter about 20% instead of 50%, so the gain is small compared to all the other disadvantages :roll: But hats off that they tried it :hut: 8) Peter The over-all s...
