A free, fully featured model rocket simulator.

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

Main features include:

  • Six-degree-of-freedom flight simulation
  • Automatic design optimization
  • Realtime simulated altitude, velocity and acceleration display
  • Staging and clustering support
  • Motor data from
  • and more!

Reliable simulations

Leverage state of the art Six-Degrees-of-Freedom flight simulation with over 50 variables. Analyse all aspects of your simulation with advanced plotting and exporting.

Easily design your models with CAD technology

Replicate all features of your existing model or new design. Everything from the density of materials to the quality of finish on the outside of your model. Choose from a massive catalog of existing components and materials, or make up your own and save for reuse later. You can even export your design drawings to PDF for building.

Optimize your designs for certain characteristics

As well as being able to tweak your model with real time feedback in design mode, there is also an AI assistant that can help you automatically adjust parameters given an optimization goal. Fly higher and longer with unique designs.

Fine tune your design with realtime performance data feedback

Performance data such as center of pressure, center of gravity, maximum altitude, max velocity and stability are all updated in real time as you work in design mode. See the effect of your changes the instant that you make them.

Design with Multiple Stages and Cluster your Motors Staging events for your flight is no problem. Multi stage, dual deployment and other event triggers can be incorporated into your design. Clustering is no problem either. Automatically arrange your cluster via several preset configurations and tune to match your exact needs.

Choose the best and safest motors for your model With a huge database of motor data from you can find the most appropriate motors for your model specifications. Easily filter and search the database for motors that are suitable for your design.
