The OpenRocket wiki provides collaboratively written documentation for the open-source model rocket simulator.
RocketPy
RocketPy provides software and information for rocket flight simulation.
About RocketPy
RocketPy is a Python library for simulating high-power rocket flight trajectories. It provides 6 degrees of freedom simulation with variable mass effects and parachute descent, and can import wind profiles and weather conditions from datasets. It also handles multi-stage rockets, design and trajectory optimization, and dispersion analysis.
Documentation includes a beginner's guide, user guide, and API reference. The API reference assumes familiarity with key concepts.
