I have never understood the apparent need of some people to instantly complicate what it is they do, or believe in. It is beyond me, and is probably a topic for a social science website.
I take a look at the wake of the C-17, and note an immense trough of disturbed air beneath and behind the aircraft. It is notable in its lack of visible moisture, evidently a high pressure zone, perhaps even heated.
The metallic and composite mass that is maintaining its altitude at the expense of an intense disturbance in the airmass remains aloft how? Kutta? Bernoulli? Glyndwr?
I make it as the result of a massive deflection of mass, period.
Can we discuss this without instantly devolving into a willy waving contest to impress? Attack? Defend? Promulgate? Dismiss? Promote?
edit... "Ah well, PJ2 told me I would get into difficulties with tip vortices ..."
So, Owain, maybe not so soon with the wing tip? Maybe the wing itself, and the paper on Newton? Simple concepts for simple people?
