Oswalds efficiency is therefore 0.9673, for lift-slope reduction to 42.03% of the 2-D value.
We will accomplish this by:
using coefficient data at an angle of attack that is 54.44% of actual (stall alpha= 24.80 deg),
and reducing airfoil lift coefficients to 77.22% of their 2-D value.
Based on AR and sweep, cm change is to 4.43% of the 2-D value.
Based on AR and TR, aerodynamic center is moved 31.56% of the way from the the 25% chord to the 50% chord.

The centroid of all foils is at 10.07 m (positive aft from CG) when the 25% chord is assumed to be the element location.
The centroid of all foils is at 10.39 m (positive aft from CG) when the wing is looked at partially as a delta-wing based on taper ratio.
The average chord of all foils is 7.24 m.
So you could say the static margin is 1.39 (positive stable) when the 25% chord is assumed to be the element location.
So you could say the static margin is 1.44 (positive stable) when the wing is looked at partially as a delta-wing based on taper ratio.
