Sorry, But this would be like picking yourself up by holding onto your
bootlaces. I’m quite happy with the bubble of air in a shield idea, but
there’s nothing for the bubble to push against which is what would make the
airplane go forward. All the propeller would do is make the air inside the
bubble whoosh around in a pleasing fashion, fluttering one’s scarf and
chilling one’s nose. And no, you can’t say the air pushing against the back
of the bubble works, that only moves the plane forward in the bubble until it
pops out the front (or the bubble generator keeps the bubble centered around
the airplane, cancelling the forward movement). Either way the bubble doesn’t
move relative to anything else outside the bubble.

Perhaps the propeller accelerates the air backwards at high speeds, which then
leaves the bubble, pushing the whole thing forwards. Sorta like an
over-complicated ion drive.
Of course you’d need to carry a lot of compressed air as propellant, but
perhaps this could be efficient if the air could be accelerated to high enough
speeds...
