Fixedwing-Airsim

Combines JSBSim and Airsim within a python module to simulate a fixedwing aircraft for Reinforcement Learning (RL)

Installation

  • Install Airsim
  • Install JSBSim
  • Clone this repository onto your system
  • Move the x8 dir into your JSBSim aircraft dir
  • Move the electric800w.xml file into the x8 dir into the engine dir

Usage

Fixedwing-Airsim has several modules that can be used to control a fixedwing aircraft:

  • main.py is the main module that uses the aircraft's autopilot top fly a simple flight profile. This would be a good place to start with the program.
  • Autopilot.py contains the basic and path planning autopilots for a default JSBSim C172 and an x8 UAV. The x8 UAV is validated against real flight data and based on an FDM developed in a wind tunnel.
  • baisc_ic.xml is the default starting conditions for the vehicle 1pixel in UE4 equals 1cm for reference.
  • image_processing.py is still in development and takes images from simulation for use with computer vision algorithms.
  • environment.py is an abstract class of an openAI gym environment.
  • tasks.py is another abstract class that defines state, space, action, reward functions for specific RL tasks.
  • jsbsim_properties.py defines properties available from the JSBSim module and controls possible I/O.
  • jsbsim_simulator.py links JSBSim to AirSim and allows for I/O out of the 2 programmes.
