Making it more stable is as simple as extending Z. You can get more involved and say extend more of the tip area of Z. Which will improve upwind even more. My mod improves upwind on the A15 too and involves extending Z at the tip. An 18m has quite limited range with a hydrofoil, low end is very good though.PugetSoundKiter wrote: I was going to try and take the higher AR Aurora2 and make it more stable. Hoping to have a better upwind angle kite than the A15, in a smaller size, and easy riding for hydrofoil use.
That is what high camber does. It causes the kite to rotate LE forward/down and reduce AoA and so fly forward. Doesn't help the rotation will cause a collapse too, as it is towards the lines and not away like low or negative camber.PugetSoundKiter wrote: when I would sheet out with my long throw bar, the kite would recover from the back stall and shoot too far forward, I suspect due to the high camber/lift.
Good you will find it works well. When you want to increase the depower and keep the ratio between ABCZ the same you will need to lengthen all BCZ together in ratio.PugetSoundKiter wrote: I’m going to follow your suggestion and go back the original A length and lengthen Z instead and then then make an adjustment to C as needed
Only error is still in Z diagram. It doesn't change depower, well unless changed extremely.PugetSoundKiter wrote: So I’ve updated the diagrams:
- Changing Z line
- Changing A line
- Shrinking B pulley line
- Shrinking C pulley line
It should be to alter the kites behavior. Correcting for pulley length with say a level mixer like Flysurfer advise will usually make a kite fly wrong because of other bridle changes.kitexpert wrote: main reason for mixer tweaking is to correct changes which have happened because lines (pulley lines, bridle) have shrunk.
The problem with original bridle lengths is they were designed for original canopy condition, which on an aged kites is not exact anymore.kitexpert wrote: Original factory settings are carefully designed and adjusted for the best general behavior of the kite (stability, performance).
I think there is many potential possibilities, some of them good to have the canopy distort for some of the sheet range. With this you have a mixed airfoil. Trick is how much and when. It seriously complicates foil kite design. Flysurfer seems to have explored it the most and given up on the more extreme implementations. Performance in a regard is certainly hindered by not keeping the skin smooth, but performance is not 1 dimensional.kitexpert wrote: Then all line rows are level, canopy is clean and well supported. Kite air foil shape is kept original while kite changes AoA when kiter sheets in/out (with the possible small effect of line row locations).
