1)Does alpha induced really exist in real life or this is just mathematical concept for calculate induced drag?
(same as lifting line theory-circulation theory is just math concept for calcualte lift ,but everyone knows that airflow dont move around wing at circle...)
2)If exist in reality,how much is alpha induced in general,are we talking about 1-2degrees or more?
(I ask this, because I cant see change of airflow angle infront of leading edge when compare 2D vs 3D wing in wind tunnel..)
2)Why induced drag is shown by lift,ist be more logical to draw resultant force and then draw drag component from it?
