Disregard buoyancy as that topic falls into a different area of physics.
Exhaustgasses said:It is the velocity (forward motion) and angle of attack that builds a pressure wedge of sorts similar to a long flat bearing surface like a rock skipping on the water.
A rock skipping on water is a also a bad example because you have two density mediums involved and an object with both forward and rotational velocity,
Exhaustgasses said:...the top of the wing can be exposed to stagnate atmospheric air pressure and the bottom of the wing is exposed to a nice 300 mph or more breeze. That wing will create lift just fine.
Do you have a diagram or a link for this situation?
I can blow air to the underside of a flat plate (top of plate at standard atmospheric temperature and pressure) and with enough airflow I can make it lift, but this flat plate is not flying.
