Equivalent theories?
Nick,
it would be nice to have an animation showing the case where the pilot adjusts collective to hold lift constant; then the pressure increase may drop out of the equation so to speak.
Nevertheless, it is obvious that if nothing is done to lower collective, and we fly into ground effect that the 'reds" will light up the plot as above, leading one to ponder cause and effect.
I'm not any kind of expert, but could it be that there is some kind of equivalence between "pressure" based explanations and momentum based explanations of ground effect? I'm sure this has been mentioned in the thread before, but I've not read all 10 pages of it.(!)
