OpenRocket is model rocket simulation software with a download and information about supported operating systems.
About OpenRocket
OpenRocket is a model rocket simulator for designing and testing rockets before building and flying them. The site provides version 24.12 for download for Windows, macOS, Linux, and as a JAR file. It also provides documentation for users and developers.
You can create rocket designs using 2D and 3D views, using custom components or parts from a component database. You can select solid rocket motors from a ThrustCurve database, set up multi-stage designs and motor clusters, and model wind at different altitudes. Simulation results can be plotted and exported, and performance data such as center of gravity, center of pressure, altitude, velocity, and stability updates while designing.
The site also links to a Discord community and GitHub for issues and contributions. It suits students, hobbyists, and others interested in model rocket design and flight simulation.
