The goal of this project is to build a robust, extensible flight simulation package for high power rocketry, with open-source dependencies. Key features considered to constitute a "robust" simulation include:
- 6-DOF kinematic model
- Monte Carlo functionality
- Multiprocessing to support large test cases
- Flexible atmospheric modeling
- Stochastic wind turbulence model
- Comptability w/ RASP (
*.eng) engine files (http://www.thrustcurve.org/raspformat.shtml) - Flight data visualization & plain-text export
- Simple input API for additional scripting & extensions
The intent is to lean on the respective strengths of python and C++ to create a modern, efficient simulation package. Python is used for pre-processing, post-processing, and data visualization, while C++ constitutes the bulk of the numerical routines. Pybind11 is used as a binding library to interface between the two sets of source code.
Current efforts are focused on builds for these platforms:

|---|---|---|
| Linux x64 | ubuntu-22.04 |
