Introduction
OpenRocket is a Free, fully featured model rocket simulator written in Java. It can be used to design and simulate rockets before actually building and flying them.
OpenRocket features a full six-degree-of-freedom simulation, realistic wind modeling, a multitude of different components including free-form fins and canted fins, clustering and staging. Read more about its features.
Best of all, OpenRocket is Open Source—its source code is freely available to study and extend. Anybody wishing to contribute to the project can do so according to the GNU GPL. Simply download the source code and start hacking, or get the ready package to begin designing and simulating.
OpenRocket is still considered to be beta software—there will still be bugs and occasional problems. If you encounter problems, please report them so they can be fixed.
