DESCRIPTION: computes aggregated aerodynamic yaw coefficient

STATUS: alpha version

HISTORY: 04/15/2000 initial release
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 Also I noticed you have some outdated files that are no longer used in the UIUCModel directory.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 Rob
2002-04-01 21:37:33 +00:00
10/25/2001 (RD) Added new variables needed for the non-
linear Twin Otter model at zero flaps
(Cnfxxf0)
11/12/2001 (RD) Added new variables needed for the non-
linear Twin Otter model with flaps
(Cnfxxf). Zero flap vairables removed.
02/13/2002 (RD) Added variables so linear aero model
values can be recorded
02/18/2002 (RD) Added uiuc_3Dinterp_quick() function
for a quicker 3D interpolation. Takes
advantage of "nice" data.
