[Flightgear-devel] UNC, Argentina:JSBsim Compilation
Thanks, i`ll join that channel !!! And About Curt experience that is a pretty close thing to what we want to do. that is wy i`m working on the numerical methods, to get the best accurancy as possible. There is also a second part of the project wich consist on adding elastic deformations to the simulation, there is a team working on bird wings dynamics. Buuut to do all that first i`ve got to learn how to compile at least jajaja-- Thank you very much for your help. _ Ingresá ya a MSN en Concierto y disfrutá los recitales en vivo de tus artistas favoritos. http://msninconcert.msn.com/music/archive/es-la/archive.aspx- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

I believe Curt does similar things. I've done something similar, but only with a pretty crude level of detail. Still, I'm fairly proud of the results. The first UAV platform I worked with was a Sig Rascal 110 (110 wing span.) With the help of aeromatic and one of the JSBSim developers (David?) we developed an initial approximate JSBsim model for the Rascal, and then based on my real life flight experience, I refined some of the model characteristics to get more realistic adverse yaw, roll rates, more realistic pitch moment relative to throttle change, etc. I then used this simulator model to develop a set of autopilot configurations (stages, gains, throw limits, etc.). At the same time, I was developing a flight computer that used the flightgear autopilot code (and property system, and xml parser.) By the time the flight computer was ready for real flight tests, I had moved on to an electric powered senior telemaster (8' wing span) for my development platform. The two airframes were similar enough, that the gains and setup developed with the Rascal simulator model worked out of the box on the real telemaster. I had stable wing leveling and stable pitch hold on my very first real world attempt with the Senior Telemaster. I was very proud of that result. The dynamics of the rascal and telemaster are different enough, that I had to do a bunch of subsequent tuning to optimize my controller, but the fact that it was convergent on the first try was really cool. (Worst case scenario is that the controller diverges and you begin shedding airframe parts in flight.) :-) For the future, I want to experiment with incorporating the nasal script engine into my flight computer. With that in place, I want to be able to write scripts to auto fly various flight test scenarios. The goal here would be to develop a set of very accurate and repeatable flight test profiles that are flown by the flight computer (as directed by the script engine at a high level). I think this would be a very useful and very powerful for characterizing the dynamics of a UAV. There's a chicken/egg issue here, but if you develop and refine the simulation model in parallel to developing and refining your autopilot configuration, I think you could boot strap yourself pretty quickly. And if we start building up a set of proven autopilot configurations for a variety of platforms, there will be an increasing likelihood that just about anyone can find a working start configuration, and then be able to refine it from there.

[Flightgear-devel] UNC, Argentina:JSBsim Compilation
Hello, My name is Gonzalo Rubio, i`m a studing Aeronautics Engineering at the National University of Cordoba (UNC) in Argentina. We are developing a project in wich we will use Flight Gear with JSBsim as the equations solver for simulating an airplane that was developed and design on the university, at the same time another team is building the plane in scale, with a wing span of 7 m. The objetive of the project is to fly both the real plane and the simulator at the same time and together with and adquisition data system compare both reality and virtual performance. I`m in charge of investigating diferent Numerical Methods for solving the equations. The reason i`m writing is because i dont have experience in C++ code compilation, i`ve downloaded the source code, but still have problems to achieve a correct compilation. Could anyone please explain me how you are doing to do this and guide me trough the process? so i can focus on the numerical methods and being able to check the results¿? Thank you very much.
