@wings of fire
Thanks for the attempt to clarify, but i do understand all the concepts you're explaining, my question however was completely different.
I meant to say that the first two statements i mentioned seem to contradict themselves because one says the transition point/separation point would be much further ahead since the aerofoil is not a flat surface (translating to flatter the aerofoil/ surface more aft the separation )
The second says the separation is just aft the leading edge because the surface has less curvature. This would imply if the aerofoil had more curvature, the separation would be much further aft (hence contradicting the first statement)
I do understand the thrust and drag definitions but when there's a force acting from the leading edge toward the trailing edge - how would that be a drag?
thanks again in advance.
cheers,
