In my previous post, I should've said that the pressure differential due to path length alone was insufficient to cause lift. Obviously, the pressure differential above and below results in lift production.
That's how I understand it...due to circulation, and the Coanda Effect, the air is accelerated and diverted downward at the trailing edge (downwash), and this forms a low pressure bond above the wing. Of course the more air that is diverted over the wing and diverted downward...the stronger the lifting gradient will be. I believe the magnitude of the downwash vector is directly related to the induced drag...so the more air diverted...the greater the lift...the greater the drag. Engineers? Am I close?
But I should stop here...as I'm getting outside of my knowledge base...and let the professional engineers take it from here.
