- Oswalds efficiency factor based on AR (5.10) and sweep (0.0 deg) is 0.90.
- Theoretical lift-slope reduction is to 68% of the 2-D value.
- We will accomplish this by:
- using coefficient data at an angle of attack that is 78% of actual (alphamax=17.3),
- and reducing airfoil lift coefficients to 90% of their 2-D value.
- Based on AR and sweep, cm change is to 72% of the 2-D value.
- Based on AR and TR, aerodynamic center is moved 0% of the way from the the 25% chord to the 50% chord.
