<h2>Introduction</h2>
<p><strong>OpenRocket</strong> 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.
</p>
<p>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 <a href="features.html">features</a>.
</p>
<p>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
<a href="license.html">GNU GPL</a>. Simply
<a href="download.html">download</a> the source code
and start hacking, or <a href="download.html">get the ready
package</a> to begin designing and simulating.
</p>
<p>OpenRocket is still considered to be <strong>beta
software</strong>—there will still be bugs and occasional
problems. If you encounter problems, please
<a href="contact.html">report them</a> so they can be fixed.
