BlackBrant waterrocket

3 chutes

The chamber were one chute is in.

At the moment i have som problem to get the pressure in my rockets but i´m looking forward that i can get a bottle from the "feuerwehr". One cotain 300bar pressing air and thats enough for my blackbrant.
But i see you´re record and thats the next step( we planed a rocket made out of a meteltube which should fly at a pressure of 120bar on a altitude of 600m.
But this are visions.

Dennis,

What are your parachutes made from? They are very colorful and would be easy to see if they got stuck in a tree by accident.

I use plastic trash bin liners for my parachutes and they only are dark green (almost black) or white. The white ones are hard to see in the overcast sky with clouds. The dark ones are hard to see on the ground.

Hi,
the parachutes are made out of a umbrella. Thats very cheap and you can built a parachute which fits to your rocket.
Here you can see the umbrella´s face;)

I agree 100%!

Unless I miss my guess, I could cut off the edges and make a smaller umbrella-chute too! I'm going to go to the second-hand shop tomorrow and look at the selection!
