How is the lift curve slope of the 3D wing calculated? In other words, which of the following 2 cases is actually used by the flight model?
Case 1) the lift curves of the AirfoilRoot and AirfoilTip are directly used to compute the lift of the entire wing, with interpolation;
Case 2) the actual wing aspect ratio (possibly corrected with the AspectRatioMultiplier) is used to compute a reduced lift curve slope (or, equivalently, a downwash angle);
In other words, does the actual wing aspect ratio (+ AspectRatioMultiplier) only affects the induced drag, or does it also affects the lift curve slope of the wing?
