Robert Deters:

Latest revisions of the UIUC code.

Revision 1.1.1.1  2002/09/10 01:14:02  curt
Initial revision of FlightGear-0.9.0

Revision 1.5  2002/04/01 19:37:34  curt
I have attached revisions to the UIUC code.  The revisions include the
ability to run a nonlinear model with flaps.  The files ls_model.c and
uiuc_aero.c were changed since we had some functions with the same
name.  The name changes doesn't affect the code, it just makes it a
little easier to read.  There are changes in LaRCsim.cxx so UIUC
models have engine sound.  Could you send me an email when you receive
this and/or when the changes make it to the CVS?  Thanks.

Also I noticed you have some outdated files that are no longer used in
the UIUCModel directory.  They are uiuc_initializemaps1.cpp,
uiuc_initializemaps2.cpp, uiuc_initializemaps3.cpp, and
uiuc_initializemaps4.cpp

Revision 1.4  2001/09/14 18:47:27  curt
More changes in support of UIUCModel.

Revision 1.3  2000/10/28 14:30:33  curt
Updates by Tony working on the FDM interface bus.

Revision 1.2  2000/04/10 18:09:41  curt
David Megginson made a few (mostly minor) mods to the LaRCsim files, and
it's now possible to choose the LaRCsim model at runtime, as in

  fgfs --aircraft=c172

or

  fgfs --aircraft=uiuc --aircraft-dir=Aircraft-uiuc/Boeing747

I did this so that I could play with the UIUC stuff without losing
Tony's C172 with its flaps, etc.  I did my best to respect the design
of the LaRCsim code by staying in C, making only minimal changes, and
not introducing any dependencies on the rest of FlightGear.  The
modified files are attached.

Revision 1.1.1.1  1999/06/17 18:07:33  curt
Start of 0.7.x branch

Revision 1.1.1.1  1999/04/05 21:32:45  curt
Start of 0.6.x branch.

Revision 1.3  1998/08/06 12:46:39  curt
Header change.

Revision 1.2  1998/01/19 18:40:27  curt
Tons of little changes to clean up the code and to remove fatal errors
when building with the c++ compiler.

Revision 1.1  1997/05/29 00:09:58  curt
Initial Flight Gear revision.

 * Revision 1.3  1995/03/06  18:49:46  bjax
 * Added dt and initialize flag parameters to subroutine calls. This will
 * support trim routine (to allow single throttle setting to drive
 * all four throttle positions, for example, if initialize is TRUE).
 *
 * Revision 1.2  1993/03/10  06:38:09  bjax
 * Added additional calls: inertias() and subsystems()... EBJ
 *
 * Revision 1.1  92/12/30  13:19:08  bjax
 * Initial revision
