RockSim is a computer program that allows you to design any size rocket, and then simulate its flight to see how high, and how fast it will fly. Even before you start building your creation, you'll find out if it is stable and safe to launch. Just image how much money you'll save by doing all your test flights on your computer!
You can also use it to find the best rocket motor combinations for your existing kits. Because nearly every rocket manufacturer uses this software, early all available rocket kits have a RockSim design file that you can open using the FREE 30-day Windows trial version or the FREE 30-day Mac trial version. Change the engines and the weather conditions to see if you have the best choice.
RockSim is also educational. That's why it is certified by the Space Foundation. Use it to teach yourself and others about the physics of rocket flight.
More modelers, teachers, and engineers use RockSim than all the other rocketry programs combined!
RockSim is available for both Windows and Macintosh OS X computers.
