How to fold a parachute

Postby Kryten » Sun Dec 16, 2007 9:55 pm

This is going to sound silly, but what's the best way to fold a parachute?
I had a problem recently with one of larger chutes, I think because I wrapped the shroud lines and all the shock cord around it.
Another time the shock cord got tangled in the shroud lines
So, can we get right back to basics and get the "best" way to fold and load a chute?

Have a look at the PML site
https://blastzone.com/pml/
Public Missiles, Ltd. Online Webstore
follow the links in the "Recovery" section to see how they recommend packing chutes -- I've had no problems using their technique

Not sure if this is the "best" way, or if in fact there *is* a best way. Some people have success with the scrunch, roll, and stuff approach, others just cram it in there. Here is how I do it:

Step 1:
Lay the 'chute out like so
Image

Step 2:
Bring the top half down over the bottom half
Image Image

Step 3:
Fold inwards so that what was the top edges of the fold meet in the middle
Image Image

Step 4:
Fold in half to make a wedge, and lay shroud lines on the 'chute so that about an inch is protruding from the bottom
Image Image

Step 5:
Fold in the side that has the double fold of fabric at the edge on third of the way, tucking in the shroud lines
Image Image

Step 6:
Fold the other edge in
Image Image

Step 7:
Zig-zag fold the 'chute like so. This picture has been take with the 'chute on its side to show the fold
Image Image

Step 8:
Roll the chute over the folds, and poke in to the end of the body tube. Note that the shock cord has already been placed inside the body, with only enough hanging out to allow easy attachment of everything.
Image

That's it. So far I have had no problems, especially when using my homemade nylon 'chutes :D

Oh, hex 'chutes are folded similar, but start differently:

Step 2:

Step 3:
SKIP

Step 4:

Hope that helps!

Edit: In case you were wondering, the 'chutes have fishing snap swivels attached to the end of the shroud lines to make things a bit (actually a lot) easier...

Thanks for the feedback
I guess I'v been lucky previously. I definitely haven't been folding like that, but I couldn't find any information about it. I would have thought the EMRR website would have had something.
I at least knew to use swivels

Yes, definitely nice one! I have been wondering about that myself. I normally just roll it all up, but have had a few tangles on occasion. I will try the described technique.

Guppzor, (Logan is it?)

That's me Steve :D I answer to most names and phrases though... :P

No problems. Like I said, I don't know if it is the best method, but it is the first "proper" method I was shown, and so far I have had no problems with deployment. Using nylon 'chutes helps a lot as well.

Would be interesting to see other peoples techniques as well...

Logan, very nicely done. Thank you!
I'll certainly be trying yours and the PML method.

Just too good Guppzor!

The slide show without any controls by itself could perhaps be confusing (too fast) but combined the pictures above it really is just perfect.

I don't know if it is easy or even possible but this thread is so good it should probably be moved over to the FAQ section.

Cheers Steve.

HTML code is off for this forum, and I don't think PHPBB has tags to embed Flash animations without a mod to it :( I could have done a controllable slideshow then :)

Edit: I suppose I could link if to an off site page for the Flash anim, but that requires me to think too much :P Might see what I can do tonight.

Double Edit: Duh, Photobucket has a slideshow feature :roll: :oops: Gimme a sec to work it out.

Mmmmmmonster Edit edit edit edit:

Clicking on the anim will take you to the slideshow where you can step forward, back, and pause.

P.S. Yes, I know I forgot a few "edit" levels, I was going for dramatic effect :P
