68 <p><strong>OpenRocket</strong> is an free, fully featured model
69 rocket simulator that allows you to design and simulate your
70 rockets before actually building and flying them.</p>
71 <p>OpenRocket features a full six-degree-of-freedom simulation,
72 realistic wind modeling, a multitude of different components
73 including free-form fins and canted fins, automatic design
74 optimization, clustering and staging. Read more about its <a
75 href="features.html">features and see screenshots</a>.
77 <p>OpenRocket is an Open Source project licensed under the
78 <a href="license.html">GNU GPL</a>. This means that the
79 software is free to use for whatever purposes, and the source
80 code is also available for studying and extending.
82 <p>OpenRocket needs help to become even better. Implementing
83 features, writing documentation and creating example designs are
84 just a few ways of helping. If you are interested in helping
85 make OpenRocket the best rocket simulator out there, please

91 <p><span class="date">22.7.2011:</span> Version 1.1.7 is
92 <a href="download.html">released</a>!</p>
93 <p>This release includes automatic rocket design optimization
94 support (<em>Analyze</em> → <em>Rocket optimization</em>).
95 You can optimize any amount of rocket parameters for apogee
96 altitude, maximum velocity or a number of different values.</p>
97 <p>While the automatic optimization is a powerful tool, it is very
98 easy to optimize against particulars of the simulation methods,
99 instead of true physical phenomena. Always keep common sense at
100 hand and take the results with a grain of salt.</p>
101 <p><span class="date">22.7.2011:</span> Version 1.1.6 is
102 <a href="download.html">released</a>!</p>
103 <p>This release includes initial localization support and
104 translations to French, German and Spanish. This is thanks to the
105 great work of Boris du Reau, and the teams from Tripoli France,
106 Tripoli Spain and ERIG e.V. If you prefer to use some other
107 language than the system default, you can select the language on
108 the "Options" tab of the preferences dialog.</p>
109 <p>The release also includes design scaling support and numerous bug
