Why do loaded ribs puff more than non loaded ribs.

[f1shlips 2]

Check the pic. Has anyone ever tried sewing a false topskin across the loaded gap to make the gap smoother?

Well, you're thinking about it backwards. It's the unloaded ribs that are causing the problem. The solution is crossbracing a smaller parachute.

They're floating up and causing the bulge? Hmm... Either way, it seems like smoothing the thing could have some benifits.

Does crossbracing smooth it?

Uh ooh, watch out for the canopy nazis. "Hey, Hey this guy is making fun of my parachute size!!!! Kill him! Kill Him"

Yeah, it will smooth out the top skin. Check out all the swoop photos on this web site. Do a search on "swoop" in the photos.


A false topskin would end up conforming to the pressurized wing structure underneath it solving nothing.

Maby. I was thinking it would make teepee shape if sewn from rib seam to rib seam. I guess it would end up bulging too though.

You could make your canopy out of honeycomb composites, that should solve the distortion problem. Of course then you'd have all those hinges in order to pack. Nevermind.

There are several possible solutions. Bulk and expense enter into the solution though. The best solution so far is cross bracing, which is still not cheap. Another solution would be to make every rib a load bearing rib, which would add a lot of line bulk (and drag), so it isn't done.

What is wrong? This one has several winglets/turbulators built in :).

Check the winglet topic :).

"another soluton would be to make every rib a load bearing rib" .already been done para flite did it 15 or so years ago. they hold the patent.2 problems tho,with aru rigging(All Ribs Utilized) the bulk is not distribuyed as well so thecanopy is real short nfat. makes it harder to get in a d abag. 2nd problem is that for some reason when an aru canopy stalls, it takes upwards of 500 feet to recover.and nothig you do can make it recover. i know a friend who worked in R&D at pfi and he stated at the time pfi would never release it as skydiving canopy because of this.but they did.
