Key mission parameters will be planned before launch and followed. The above will likely evolve as the community chimes in on what rocks their world and what doesn't.įor the Simulated Space Missions, it will not be Kerbal-style grab the joystick/smash the keys seat of the pants execution. Components for Expander Cycle and Staged Combustion Engines.“The longer-term plan is to have the following features:

How is the full version planned to differ from the Early Access version? It already has three years put into it, and now is the time to gather and reflect on what others think about it.”Īpproximately how long will this game be in Early Access?

I have a pathological need to get rocket engine simulation into the hands of as many people as I can as fast as possible.

If you have ideas on how to improve the program or find an error, please open an issue ticket for discussion or file a pull request if possible.“It is a complex niche game that depends on a cult following to give feedback to make it relevant. I believe this is the best way to avoid bugs and also the easiest way to get new features added to the software.

ContributingĪs openMotor is open source, one of the goals of the project is to have as many eyes on the code as possible. Check for yourself (and file an issue ticket!) if you doubt the results. The source code is distributed so you can build cool stuff with it, and so you don't have to trust the calculations are being done correctly. OpenMotor is released under the GNU GPL v3 license. The remaining user information, like propellant data and preferences, is stored in plain YAML files in \Local\openMotor on Windows, /Users//Library/Application Support/openMotor on Mac OS, and /home//.local/share/openMotor on Linux. The recommended MIME type for these files is application/vnd.openmotor+yaml. ric to differentiate them, but internally they are YAML and can be edited in a text editor if desired. After the venv has been activated, the programs python and pip are aliased to the python runtime specific for your venv, so use those (instead of pip3 and python3, on e.g. Once everything is set up, you can start openMotor by running: python main.py Note: On some systems, Python 2 and 3 are installed simultaneously, so you may have to specify which version to run when creating the venv. ui forms, you must re-build using the same command. Note that if you make changes to the UI using the.

The easiest way to build/run from source code is to clone the repository and install the required dependencies into a virtual enviornment: Because the PyQt5 bindings are used for the GUI, Qt5 must also be installed. The dependencies are outlined in requirements.txt, the main ones include PyQt5, matplot, numpy, scipy, scikit-fmm, and scikit-image. The program is currently being developed using python 3.10. Alternatively, you can run it from source code to get the latest features. From there, just unzip the file and run it. You can download the latest version for your system here. The calculations involved were sourced from Rocket Propulsion Elements by George Sutton and from Richard Nakka's website.

Detailed output of every calculated parameter at any time and position along the motor.

A UI that supports saving and loading designs along with undo and redo.

The grain editor displays how a grain will regress to cut down on the guesswork involved in tweaking geometry.

A propellant editor that allows the user to enter the properties of as many propellants as they wish.

Loading custom grain geometry from DXF files.

Support for common grain geometries such as BATES, Finocyl, Star and more.

It uses the Fast Marching Method to determine how a propellant grain regresses, which allows the use of arbitrary core geometries. The software estimates a rocket motor's chamber pressure and thrust based on propellant properties, grain geometry, and nozzle specifications. OpenMotor is an open-source internal ballistics simulator for rocket motor experimenters.
