Introduction
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!
