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

Since our founding in 2003, we've become 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.

Suggestions for High Pressure Equipment?

Post by skysaber89 » Wed Aug 31, 2016 7:39 pm

Hello everybody

I asked a similar question to this last year sometime, but I did not get but one or two responses. The responses I did get were somewhat sketchy in their suggestions, as well. So here I am back at the best repository for anything water rocket related with a question I must pose.

This is for the more advanced teams/builders on here. My team and I were planning to design and build a high pressure rocket, one that could be used up to 300 psi or more. My question for you guys is this: what suggestions would you have for achieving these high pressures? What kind of equipment would be suggested so that we may undertake this massive project? My current setup is capable of (max) 200 psi, and it gets kind of iffy when we get around that area. We usually launch with, at most, 150 psi. I know I will need to get some higher pressure hoses, but what kind of compressor setup could I use? We don't have several thousand dollars to spend on crazy scuba compressors, so we would be fine with air tanks as well.

Along with your suggestions, what kind of price range would we be talking here?

The JARL Division thanks you for any help you can give us.

Hi,

If your thinking of using scuba tanks then take a look at Air Command http://www.aircommandrockets.com/home/.htm

He has great detal on setup etc. His high pressure rocket was 750psi I think or somewhere around there.

He also has step by step how he made his rocket

Regards

Al

Here it is: http://www.aircommandrockets.com/home/.htm

For some reason it removed the scuba for me too. I had to use the BBCode . Weird, but what ever.

Expensive equipment, not ordinary people can use.


I come from China, do not understand English, your information I use the translation software to view. I like water rockets, technology is the same, I hope we can become friends.
