To Whom it May Concern, and to Whomever may be of
assistance,
I'm working on modifying a
jsbsim FDM to represent an RPV with an autonomous autopilot. The autopilot
andgnc systems are designed in Simulink, and we're using flight gear as
the visual and dynamics model for the aircraft. I'm
Actually Jon, I haven't hacked together an electric
motor. Sorry my post implied that. I was hoping someone could help
me get started with that. The Config file that I've been modifying is one
of a glider. ASK21, so there is no powerplant, but many of the geometrical
characteristics are the
In the prop file "prop_75in2f.xml" what is
the input column for the Look up tables of C_THRUST, and C_POWER. The
first column that is

So if I know the range of velocity in which our
plane will be flying, and the specs on the electric motor (600 speed motor),
along with the Diameter of the single blade prop (11"), than I could calculate
the advance ratio along eachvarying flight conditon. Is that
Correct? The next thing
thanks for the tips. So you're suggesting
that
I leave the J (advance ratio), and coefficients
alone,
and just modify the Ixx and Diameter parameters
accordingly?
DONE! Well, this kind of leads me back to the
original problem.
My plane is supposed to be flying to a set of
waypoints,
I thought I read somewhere, that in Flight Gear,
the CG of your aircraft isn't specific to the aircraft itself, but rather
related to some sort of reference. Is this true? Or did I
misinterpret something? It also mentioned that you could put the
coordinates of (0,0,0) for CG location.
Some good thoughts again. Actually, I'm using
a JSBSim flight model, within flightgear, but interfacing it to my own autopilot
inside of Simulink. I might however switch over to the Flight Gear
Autopilot, and see what kind of handling I get. Which address should I
send the file to?

does anyone know of the equations that are used to
determine how coordinated a turn is? I
notice in the hud view mode there is a coordinated
turn gauge, and in the distant modes, there
is also a coordinated turn indicator.

How do I insert a disturbance through a command
line call. I'd like to test my adaptive autopilot, and its
robustness, by inserting some wind/disturbance at a specified time.
Should this be done through the command line?
thanks

how about through a command line?

David,
Once again, Im having some issues with my
engine model. When I Browse Internal Properties I notice that
the rpm gauge is registering 200k. OUCH! I also note that the starter, and
engine are checked as not running. Is there something obviously
wrong in one of my files? I believe
