WebWhat's the angle between the downwash line and the airfoil line (it's now 15 degrees). … WebEstimation of the rate of change of downwash angle at the tail with wing angle of attack is another parameter that requires careful estimation, and for the same reasons. Typical values are in the region of dε/dα ≈ 0.5, but the geometric location of the tailplane with respect to the wing strongly influences the actual value. Again, a value ...
