Take an overview of the development process of the virtual cockpit, introduced the AC3Ds characteristics that. The use of simulation environments to test the UAVs design and control systems is an important phase in their development cycle, since it reduces the time and the risks associated with the real flight. based on Flight Gear simulation platform. In some cases, these UAVs are flown autonomously by on-board autopilots, with highly integrated systems and complex control laws. Introduction Small Unmanned Aerial Vehicles (UAVs) are increasingly used by researchers, hobbyists, civilian organizations, and the military for different purposes, due to the lack of risk to a pilot and their low cost. Keywords: UAV Modeling, UAV Simulation, JSBSim, FlightGear 1.

This paper concluded that modeling and simulating a UAV accurately is not an easy task, due to the need to calculate many parameters either by physical measurements, experiments, or estimation from available data of similar UAV, or by software tools. A good autonomous flight simulation was performed. The outcome of the paper was a complete JSBSim flight dynamic model for the Cessna-182 (RC), with 3D model for visual simulation and an effective autopilot. In order to use the chosen waypoints with FlightGear navigation system, a unique ID was assigned to each waypoint, and the FlightGear database was altered to include the new waypoints with their IDs.
Finally, a flight path, which contains a number of waypoints chosen over a selected area using Google Earth map, was constructed. To fly the modeled UAV autonomously a tuning process was made for the built-in generic PID (proportional, integral, and derivative) autopilot of FlightGear, which has the ability to hold aircraft velocity, vertical aircraft speed, altitude, pitch angle, angle of attack, bank angle, and true heading. In order to perform a visual simulation, a 3D model for the Cessna-182 (RC) was created using AC3D, a commercial 3D modeling software tool. The next step was to make educated guesses to refine important sections in the created configuration files with the assistance of available data of similar UAV.

The first step was to create the required JSBSim aircraft configuration files by using the Aeromatic v0.8, a free web application to create aircraft configuration files for use with the JSBSim. This means that one can uses the popular GMax to design anything from aircrafts to scenery.When you want to export a model. This is not true.FlightGear supports a variety of formats, among them is 3ds. A small commercial electric engine Cessna-182 radio controlled (RC) aircraft was chosen to represent the UAV. A lot of people have the misconception that FlightGear only supports 3D models in ac3d formats. Nasr *** Paper: ASAT-13-US-01 Abstract: This paper describes the use of FlightGear, an open-source flight simulator, and JSBSim, an open source flight dynamics model, to model and simulate a small autonomous Unmanned Aerial Vehicle (UAV).
