Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

The largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

Waterrocket 142 meter or 468Feet with onboard camera!

Post by Daan.[D&P]Rockets* » Tue Oct 14, 2008 5:22 am

Hi people,

Now we finaly have our flycamone2 camera. And last sunday we did a flight with it.
There where some - points. Like the hole in the parachute compartiment for the lens of the FCO2 was a bit small. So u see in the corners of the onboard film some white quarter cirkels. And the rocket did get into some low hanging clouds so the quality of the footage was not verry high. It was a bit foggy up there :)
And the sun was standing low and did shine directly into the camera. So the camera had to switch constantly from verry bright light to a bit darker. But its still a pretty nice movie!

And we will fix the parachutes so the recovery is a bit smoother :)

Have fun!

Go to youtube and choose high resolution/quality! for a better vieuw!

Very good video! Great job.

What have you done to help make the parachute stable?

We are using shock cords to absorb the pressure on the main chute strings. Some elastick bands tied up to the chute. So if there comes a big pressure on the string it will strech out a lot! and increase the pressure on the parachute strings. This works verry nice!

But the cords where not the identical lenght.. Thats why it was a bit wobbely :)
We are going to fix it and launch next weekend if the weather is nice..

Just an update:

Yesterday we did get some carbon sleeves! next week pleun is going to epoxie it on a rocket. So in maybe 2 or 3 weeks we are going to launch high pressure rockets reïnforeced with carbonfibre!

How big is your sleeve? The sleeve we got last Christmas has proven only large enough for very thin rockets. We don't get much volume with our size sleeve. Only drinking water bottles come in this narrow size and they have decorative shapes molded in the top and bottom so we can only use about 4" of the middle of the bottle for our body tube. There's going to be many, many splices to build a long tube. :cry:

Hi,

We bought us a 4.0" Std AeroSpace hvy 15.1 Extends from 1.6" to max 4.4".
Ideal for bottles with an diameter of 85 mm.
We bought our composites at sollercomposites.com.

I hope we can start with epoxying the carbon to the rocket next weekend. It depends on when Pleun got the epoxy glue and hardener.

I cant wait to launch a high pressure rocket ! :WRA2:
