51 <p><strong>OpenRocket</strong> is a Free, fully featured model
52 rocket simulator written in Java. It can be used to design and
53 simulate rockets before actually building and flying them.
55 <p>OpenRocket features a full six-degree-of-freedom simulation,
56 realistic wind modeling, a multitude of different components
57 including free-form fins and canted fins, clustering and
58 staging. Read more about its <a href="features.html">features</a>.
60 <p>Best of all, OpenRocket is Open Source—its source code is
61 freely available to study and extend. Anybody wishing to
62 contribute to the project can do so according to the
63 <a href="license.html">GNU GPL</a>. Simply
64 <a href="download.html">download</a> the source code
65 and start hacking, or <a href="download.html">get the ready
66 package</a> to begin designing and simulating.
68 <p>OpenRocket is still considered to be <strong>beta
69 software</strong>—there will still be bugs and occasional
70 problems. If you encounter problems, please
71 <a href="contact.html">report them</a> so they can be fixed.
