Bernoulli and Newton
This has the potential to bring out the fanatics on either side but the truth is the correct answer is "both."
There is in fact a low pressure area ahead of the prop. And you can apply Bernoulli type physics in this case.
But you can also make a case for Newton in that the prop is taking an airmass and accelerating it rearwards..."for every action there's an equal and oppsite reaction."
Definitely two ways to look at it. Two different theories describing the same phenomenon.
And now I'll wait for my lashings.
