Hello, Looking at the default 747 after updating to SU9 beta, if I open the
stall debug window, here is what I can read about the wing twist:
I do not quite understand the
information shown about wing twist. What is the “Add to tip twist”? Where does
it come from? Why is the middle wing AOA negative? If the wing incidence is
2°, then it should be 2° more than the plane AOA (2.2°), and show 4.2° instead
of -1.1°. In a similar way, if the wing twist is -5°, then the left and right
wing tip AOA should be: Tip AOA = plane AOA + wing incidence + wing twist =
2.2 + 2 + (-5) = -0.6° Can you explain this debug window? Thank you!
In the CFG for the new 172, we have some additional parameters. As for how
they work, and how to correctly configure them, your guess is as good as mine.
Stall_AileronAddIncidence = 1
Stall_TipAddIncidence = 2.0
Stall_TipAddTwist = 5
Stall_TipTwistScaleRatio = 1.0
StallDef_StartRatio = 0.9
StallDef_EndRatio = 1.4;
StallDef_CurvePower = 1.1;
StallDef_minTransition = 0.025;
StallDef_airflowdetachspeed = 10
StallDef_airflowattachspeed = 10
Thank you! That will surely help, now we only need to wait for these
parameters to get documented.
@FlyingRaccoon, Hi Sylvain, could it be
posible to explain these pararements? I am having trouble with my project to
replicate the stall behavior as per real world, a particular problem is my
airplane never incurs on stall spins… it only stalls forward and I am
wondering if these parameters could help me to tweak things further in order
replicate it. Regards, Raul
Hello We’re working on it, I’ll come back to you as soon as I have the updated
doc content. Regards, Sylvain
