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.


This forum is for new members to introduce themselves and tell us how they got started in water rocketry.

I created this program for calculating the launch trajectory. It also allows you to set a target altitude, velocity, or distance and will tell you the rocket configuration to accomplish that target. This is free for anyone please try it out and give me some feedback.

Windows is required and so is the visual c++ runtime. the run time can be downloaded here if needed: https://www.microsoft.com/en-us/downloa ... x?id=48145

This software is and will always be free. Feel free to share it as you will.

After bypassing the warning about an unknown publisher, it took suspiciously long to even get to the admin permission prompt, so I cancelled it.
And now my hard drive is running continuously. It seems the Microsoft System Protection background task was triggered and it's now consuming my hard drive transfer capacity.
