I'm really confused about how an annular wing would work. Wings generate lift because they have a specific cross-sectional shape. Surely if you turn that into a ring the lift generated by the upper part will be cancelled out by the downforce generated by the lower part.
Also you've got a lot of wing that's functionally doing nothing in horizontal flight apart from adding weight and drag.

Wings generate lift according to the angle of attack. A symmetrical wing can generate lift. Also, consider that many planes can fly upside-down.
The specific cross-sectional shape allows them to produce lift at a lower angle of attack, without stalling. That's particularly useful if you want to take off.
There's also stuff like the Coanda effect, Bernoulli's principle, and lots of other complicated stuff, eventually ending in "nobody knows".
