How to Fold a Model Rocket Parachute

If I fired a 58" diameter chute out of a tube with air, what do you think the smallest diameter tube I could use is?
Thanks man

Hmm. I guess that depends upon the type of material the chute is made from, the shape of the chute (flat disc, flat X, dome, etc), and prolly the number, size, and anchoring type of the shroud lines.

The easy way to make sure the chute deploys is to use a piston. Google [rocket recovery piston parachute] and you'll see all kinds of solutions for that.

I am guessing that a 58" thin-mil Top Flite could probably be deployed out of a 2.56" (BT-80) tube. EMRR and other sites might have more info.

I don't think it's ripstop. It's just an easy thin nylon with about the radius of 1 meter and it has a hole on it's top to prevent to big forces. I could make a vid about it or some pics if you'd like it but nowadayz I'm quite busy in the school so I can't promise quick reactions :)
When I had had a working water rocket the canopy didn't open in time because of bad folding. I'm quite sure it will.

Thank you, man! It was useful. I've made a similar one out of nylon. Mine it's far bigger and not precise but I think it gonna work on mine also. Can't wait trying it out! I should only make a working water bottle also... lol

You are putting a ripstop nylon parachute on a two liter bottle rocket? How?

how do i get the parachute to deploy?
im using kno3 rockets and im building a big one, should i put a charge behind the nose cone?

Well, there are as many different answers to that one as there are kinds of rockets available. I suggest you do some Google searching for ["model rocket" parachute deployment methods] or some such and see what comes up.

dude you talk to much

Who is this "much" with whom I am supposedly conversing?

Thanks Marty! I'll see if I can figure this out!
