How to simulate a fixed-wing UAV and obtain its longitudinal and lateral linear systems (LTI)

Example how to simulate an unmanned glider and extract flight dynamics for trimmed gliding.

An implementation which simulates the non-linear flight dynamics of a fixed-wing unmanned areal glider with Simulink and visualizes the UAV's behavior using FlightGear.
Includes tools to calculate aerodynamic coefficients using the Tornado vortex lattice method implementation and provides a script to extract longitudinal and lateral linear systems for the trimmed gliding state.
