I've always thought about using a small estes engine to deploy a chute for larger projects. Would be nice to have a chute ready almost instantly in an emergency.
Can't you scratch the bottom quick link and attach the shock-cord directly to the body coupler (the metal "U")? Also, it seems strange to really need that heavy-duty metal U ring for just a couple of Kgs falling from the sky. Can't you design the U directly into the 3D-printed body-coupler part? Even if it's gonna be bulky, I imagine a bulky 3D-printed U would be way lighter than the metal alternative. A decent amount of weight could be spared here, no? (Disclaimer: i'm not into DIY rocket, just a curious guy). Cheers
yeah even regular nylon zip ties are rated 50-175 pounds. 1/4 inch (6mm) nylon rope has a breaking strength of 1100 pounds, and would weigh 98% less than the U bolt and quick links.
if you have inflatable (flammable) nose-cone, activated by heat, even from re-entry, it can be metal-hydride to poof it up, combo self-inflating solid-state floater-parachute
You built the piston upside down.. The closed side of the piston should face the energy that is going to push it.. Just as it does in an internal combustion engine.. Assembling it upside down will make it chatter as it rides the inside of it's cylinder..

Interesting idea, a rocket powered ejection piston! :D
Great build. I'd probably use a butterfly knot for convenience instead of the tautline hitch knot.

I will maybe try this. Thank you for pointing this out! :)

Nice video! I call that knot a taught line hitch. It’s used to tie up the stern of sailboats

2:35 The knot was a noose :/
Nice!
So I burnt and heated up a piece of wood that was stuck to a rope (that would connect to the parachute using wax and clay for no reason? Come on...
any one here in 2024
no
Make a pulpolsive landing system
He is! It's a work in progress, but its going along well!
Yes
Lmao
