It has been awhile since there has been a significant update for the JSBSim Sfunction project, but finally we are pretty close to a new release that has some cool new features.  The most significant of these is the addition of the FlightViz 3d…

"Please download the latest release here: http://dl.dropbox.com/u/5284957/JSBSim_MATLAB_release.zip

It is still quite "beta" and because I do not have a 32-bit machine at the moment, there are only win64 versions of the MEX files compiled. I hope to…"

Brian Mills replied to Brian Mills's discussion UAV Flight Model Validation, Trim and Linearization using Matlab
"Hi Nikki,

OK, I found an error in the simulink model used for the trim- not sure how that version made it into the release but it only trims the 'f16' model, no matter what model you select. This would explain why the C172 model will not trim. I…"

"Hi Niki,

Thanks for giving the project a try! To address your problem with the trim, let me first tell you what someone more knowledgeable of the subject than I has said on more than one occasion- "trimming an aircraft is a non-trivial task." What…"

"TRIM, LINEARIZATION, EIGENVALUES AND 64-BIT

A major new upgrade to the JSBSim S-Function project will be released very soon - a trim and linearization function! The foundation for the trim and linearization script was originally part of the Aerosim…"

"Hi,

I'm a Commercial Flight Simulator Support Engineer in Tokyo Japan and I am very impressed with the projects you guys are working on. In case any of you want to use Matlab/Simulink, I developed a JSBSim SFunction that would be great to use for a…"

"I think Roy is right in that JSBSim may not be a good choice for rotorcraft. I think that flight models using blade element theory are better for those types of vehicles. In fact, the flight simulation company I work for uses JSBSim type flight…"

"Joe,

The project is available for download on the mathworks website - http://www.mathworks.com/matlabcentral/fileexchange/?term=jsbsim

The s-function is already compiled for win32. Enjoy!"
