JSBsim
An open-source, multi-platform flight dynamics model (FDM) library for aircraft and rocket simulation, written in C++.
What is JSBsim?
JSBSim is an open-source flight dynamics model (FDM) library that simulates the physics and control of aircraft, rockets, and other vehicles. It provides a high-fidelity, nonlinear 6-DOF model that can be integrated into flight simulators, used for drone autopilot testing, or applied in academic and industry research. The library is written in C++ and offers bindings for Python, MATLAB, and Unreal Engine.
Aerospace engineers, flight simulation developers, drone autopilot testers, academic researchers, and anyone building high-fidelity vehicle dynamics simulations.
Developers choose JSBSim for its NASA-validated accuracy, extensive configurability via XML, and broad integration capabilities with popular simulation environments like FlightGear, Unreal Engine, and MATLAB Simulink.
