25.06.2014: Version 14.06 is released! This release contains very minimal changes. It fixes an annoying bug in tables that many people experience. A texture is added for Klima motors.
21.05.2014: Version 14.05 is released! This release contains some minor features, bug fixes and updated thrust curves. New motor vendors Klima and Southern Cross Rocketry are included. The simulation will now compute optimum delay based on actual coast time. Components with CG and mass overrides are decorated with an icon in the component tree.
21.03.2014: Version 14.03 is released! This release contains the new photo realistic renderer (in the Tools menu) which allows one to visualize the rocket in the air. There are various bug fixes in the configuration and motor selection windows as well.
These are packages ready for use and are the recommended download for normal users. They are pre-packaged with motor thrust curves from thrustcurve.org.
OpenRocket requires Java version 6 or later. The Sun Java Runtime is recommended.
This is the latest version of the desktop version of OpenRocket. It contains the latest and greatest features, and runs on any system supporting Java.
OpenRocket can be started in most graphical environments (including Windows) by double-clicking the package icon. No installation is required.
From the command line OpenRocket can be started by java -jar OpenRocket-15.03.jar
The Android version allows opening OpenRocket files, viewing simulations and motors. Later versions will allow running simulations as well.
The Android version is thanks to the fantastic work by Kevin Ruland.
