How to build a parachute for your water rocket
A strong and reliable parachute design is very important to anyone wishing to develop a water rocket with a recovery system. Any system from a simple Air Flap mechanism to the sophisticated ServoChron(tm) electronic deploy system relies on a well made parachute. This tutorial will reveal the secrets to easily making a parachute that will safely recover your water rockets.

Not cool.
You shouldn't recycle the work of other people and not give them credit.
We already have one too many CopyKatz on this forum.

Re: How to build a parachute for your water rocket
Wow, you guys made a great tutorial.
About a year ago I was making a few parachutes for a school project on their shapes vs their fall time and it would have really helped if I had known about all the resources you guys have on your site!

Re: How to build a parachute for your water rocket
I am making a water rocket for class and I am using circle table cloth for a parachute. The parachute works very well but I can't find a cone that covers the parachute and also comes off so that the parachute will deploy. Any suggestions on a cone to use that will cover a large parachute and will also come off easily?

Re: How to build a parachute for your water rocket
Exactly how big (diameter)? Also are we talking plastic disposable table cloth or something thicker?katepeterson wrote:I am making a water rocket for class and I am using circle table cloth for a parachute.

It is a disposable tablecloth and it is 3 ft in diameter it also
has elastic around the edges to give it shape.

Re: How to build a parachute for your water rocket
Ok I have some of that stuff. What size bottles are you using? Also, do you want to.put on a timer with release or just have the nose separate at apogee?katepeterson wrote:It is a disposable tablecloth and it is 3 ft in diameter it also

Re: How to build a parachute for your water rocket
The bottle is made of 1 and a half 2 liter bottles. I am not allowed to use any timers or parachute deploys systems so yes I want the parachute to release at apogee.

Re: How to build a parachute for your water rocket
So there's a couple events that you'll have to deal with-katepeterson wrote:The bottle is made of 1 and a half 2 liter bottles. I am not allowed to use any timers or parachute deploys systems so yes I want the parachute to release at apogee.
1. Prelaunch 1g
2. Launch- thrust phase 14g?
3. Launch- coast phase -2g?
4. Apogee- 0g
5. Descent
The other thing to remember is gravity acts on falling objects the same. In other words, things just don't "fall apart". Instead they tend to fall together.
So my advice is to add a bit of weight to the nosecone itself to keep the nosecone on during stage 1 and 2.
Add flaps on the bottom edge of the nosecone to keep the nosecone on during phase 3.
And finally, add a compressible spring like piece of memory foam or loop of PET bottle. to cause the nosecone and bottle to separate during phase 4.
Final thought- parachute is really large for that size of rocket. Unless you are trying to maximize time aloft, a smaller chute might be easier to manage.
Hope this helps!
