As with the prop therefore the majority of the thrust comes from the front of the blade.
May I refer you to my answer above. If that is the case, how can an asymetrical wing generate lift when upside down? I suspect the majority of the lift comes from Newtons 3rd law, a reaction to the wings surface pushing the air down due to its angle of attack.
However. That still is unsatisfactory. Newton or Bernoulli, at the end of the day you have a lower pressure on top and a higher pressure underneath, the same result for two entirely different and yet combined reasons. I would venture to state that you cannot say pull/suck or push. You can only say that the aerofoil will want to move away from the high pressure.
