the faster flow over and above the upper surface meeting the

flow under and below the lower surface effectively turns the

downwards which provides that change of velocity which with
the air
mass flow, provides the Newtonian mass rate times acceleration
called the ' momentum change' - is the lifting force

nah. that's barroom talk after the three beer. It won't
design any airfoils
at all.

So, you don't agree that a change in momentum [of air] is needed
to create a [lift] force?

This seems to confirm that you live in a different universe from
the rest of us, Jax .
