So wings work by forcing air to move faster over the upper surface than
the lower surface, thus causing the air pressure above the wing to be
reduced compared with the air pressure below it.
In order for this to happen air has to rush over the wing some how.
Could the pressure difference be accomplished another way, thus allowing VTOL (Vertical Take Off and Landing)?
I think it can, but I'm not exactly sure how :-)
Could vibration be used to reduce the air pressure above an object?
Possibly.
Sound or microwave?
No idea.
But this got me thinking.
The effect sought is a comparatively reduced air (atmospheric) pressure above the object (the craft) producing the effect.
Since the pressure is felt by the object in PSI (Pounds per Square Inch), the surface area subject to air pressure is at the heart of the equation.
So if an object was created that had a greater down-facing surface area than up-facing, would it simply lift?
No applied energy.
Does anyone know why this (at least in theory) can't work?
