Re: DIY Foil Kites

Laid flat, the LE is very curved at the ends. The TE is much flatter. The picture in the lines plan, that you also have is not accurate and is laid flat anyway. I compared my design with the real thing laid on the floor. In the design, I tried with some approximation to get as close as possible to t...

Re: DIY Foil Kites

Captură ecran (31).png This would be the spanwise cascade except the 1 at the tip, because the program insist to pair this with the next(5) I made the width of the panels proportional to chord which is a good approximation of the real canopy I set the anchor points according to the last (in the cen...

Re: DIY Foil Kites

Seam allowances are inside the cells of course. On the outside I also did an extra sew, afterwards, I packed the whole in the inside out of the kite, with about 6 needles as marks, sewed and pulled the kite out from that salami :) Indeed the As are not at 0 but few centimeters inside , like about 12...

Re: DIY Foil Kites

But these sections you are going to use have only a small part of the curvature of original wing. You're right, and the foils are set radial. I stopped playing wit=h SP an took the pluge! I cut the PG and sew it with no problems, 37 cells.Took some 3 hours so far. I do hope tomorrow to have two hou...

Re: DIY Foil Kites

The computed PG height of curvature is only 27% I meant that due to cutting of the central 19 cells, about 4 m, the projected length became only 5 m but the height remains and the 2 parts to be merged, will want to keep their shape. I did this by horizontally translating one part to another. What I ...

Re: DIY Foil Kites

I thing I screwed up something. The canopy is not in my workshop but in the house. was working with my first measurements and guestimates from yesterday. [/quote]But middle cells are much bigger than cells at tips. Is difference really that small? Hard to believe. klimm wrote:[/quote] It is maybe la...

Re: DIY Foil Kites

In order just to translate the two parts resulted by eliminating the 19 central cells, this means keeping the absolute curvature height at 250 cm, I computed in the Canopy Shape dialog box, a curvature height of 50 (suppose it is percent)

Re: DIY Foil Kites

Looks good,
for the whole PG I computed a curvature height of about 250cm for a projected span of 922cm
What is the curvature height at your design?
sorry I was in gimp for a while

Re: DIY Foil Kites

I measured the chords 1,2,3
the tip-1=38cm 2=62 3=85
Of course the chords can't be exactly measured but 1 is for sure 38
