I am wondering if enough lift can be created for a VTOL aircraft using a propeller that is extracting air from a cylinder which is closed at one end and has holes in the top half of the cylinder.
Please reference the conceptual drawing below.
I believe that when the propeller is turned on and air is flowing in through the holes and out of the cylinder, there will be low static pressure inside the cylinder and the cylinder will be lifted up by the ambient air pressure outside the cylinder pushing against the bottom half of the cylinder. Lift should occur because the bottom half of the cylinder has a larger surface area compared to surface area of the top half of the cylinder which has holes in it.
So, would a propeller extracting air from a cylinder with holes in it be an ideal lift apparatus for a VTOL aircraft?
