hpr-sim

Overview

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:

Platform	Runner OS	Test(s)
Linux x64	ubuntu-22.04
