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.

Hello everyone.

Please forgive me if I posted in the wrong section, but I have a questions about the simulators.

Would you mind telling me how the simulators are created? What equations are being used? What assumptions are being made?

Also, which simulator would you recommend?


Thank you very much! <3

Nice to see you back.

The original download page was hosted on a different site to Paul's main Compuserve pages (which are now all gone). However the Internet Archive can stilll get you quite a lot of the content, and I found the link to the simulator download page.

http://web.archive.org/web/20080116095127/www.dl.files2.serveftp.net/wrcmdp.htm

I'm also attaching the zip file here, but you may have to check the page above for instructions.
You do not have the required permissions to view the files attached to this post.

The new location of this seems to be here: http://grosse.is-a-geek.com/paul/h2orckt.htm
... unfortunately, the download link doesn't work. But that site has some useful information about water rocketry, so it's worth visiting.

There's another very good simulator here: http://www.seeds2learn.com/rocketSoftware.html
The downloads are available for Windows, Mac, and Linux.
