A free, fully featured model rocket simulator that allows you to design and simulate your rockets before actually building and flying them.

OpenRocket is an free, fully featured model rocket simulator that allows you to design and simulate your 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 and see screenshots. OpenRocket is an Open Source project licensed under the GNU GPL. This means that the software is free to use for whatever purposes, and the source code is also available for studying and extending. OpenRocket needs help to become even better. Implementing features, writing documentation and creating example designs are just a few ways of helping. If you are interested in helping make OpenRocket the best rocket simulator out there, please Get involved! Features:General Fully cross-platform, written in Java Fully documented simulation methods Open Source, source code available under the GNU GPL User interface Easy-to-use user interface for rocket design Real-time view of CG and CP position Real-time flight altitude, velocity and acceleration information from a continuous simulation performed in the background Zoomable schematic view of rocket from the side or rear, with rotation around the center axis Design A multitude of available components to choose from Trapezoidal, elliptical and free-form fins supported Support for canted fins (roll stabilization) Staging and clustering support Automatic calculation of component mass and CG based on shape and density Ability to override mass and CG of components or stages separately Simulation and analysis Full six degree of freedom simulation Rocket stability computed using extended Barrowman method Realistic wind modeling Analysis of the effect of separate components on the stability, drag and roll characteristics of the rocket Fully configurable plotting, with various preset configurations Simulation data can be exported to CSV files for further analysis Simulation listeners allowing custom-made code to interact with the rocket during flight simulation
