The main rocket design window is used to design the rocket and it also provides information about a flight simulation in real-time.
You can analyze the effect of individual components on the stability, drag and roll characteristics of the rocket.
The simulation results can be plotted in a multitude of ways. You can either use the predefined plot configurations or define your own.
- Fully cross-platform, written in Java
- Fully documented simulation methods
- Open Source, source code available under the GNU GPL
- 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
- 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
- Automatic design optimization — you can optimize any number of rocket parameters for flight altitude, maximum velocity or a number of other values
- 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
Planned future features
OpenRocket is under constant work in the free time of the developers. You can have a sneak preview on what has been planned by checking the TODO-file on github.
Below are a few major features that are under consideration:
- Aerodynamic computation using CFD (help needed!)
- Better support for supersonic simulation (help needed!)
- Customized support for hybrid rocket motors and water rockets
- Importing and plotting actual flight data from altimeters
- Rocket flight animation
- A "wizard" for creating new rocket designs
- More ideas are listed in the TODO-file!
