Answer is no.

Find America's Cup on video (ESPN...etc.).
Video doesn't do them justice.
Having seen them race up close....amazing.
Their sails are wing planeforms.
They fly sideways.

To negate downward gravitational forces ??

Well, operating in the third dimension, there will always be width where there is height. So now, a wing would not have to be longer horizontally than vertically, but it would require much more power to run. It would, however, make the aircraft incredibly maneuverable to have a sideways wing.

well now that you edited it to have an answer i look stupid....

See what happens when your not patient? It's vacation time quit thinking so hard! Check out the Newport videos. I'm on a boat called "RUM RUNNER". It's an actual smuggling boat. 1930's with an airplane engine. You may see it...2+ helicopters every day.

Oh, I think you were right, too.
The round wing works. Made an rc yrs. ago.

Aww that's want a was going to say Calvin

lol, i log on and answer a question and im impatiant. jk, lol, maybe put the body of the post in before you post next time.

lol sput

At 136 you are lucky that I ever get to post before it time outs.
Check "round" or "circular" wings. Control was the difficulty.
Used to fly all sorts of rc planes. Lots of made-up ideas. Will it fly? Let's try. When I traveled across the country I always had a power & glider rc plane. The experience of flying my 11ft. glider at the Grand Canyon, Yosemite, & the Golden Gate Bridge were wonderful. She had cameras before they were easy to do.
When you travel...take the "BLUE HIGHWAYS" (it's a book by William Least Heat Moon, I believe).
....an take a plane......

As long as the angle of attack (of the airfoil) does not go beyond it limits you have lift produced by the wing. If the angle of attack for a given airfoil exceeds the angle of attack then the wing stalls because the air no longer flows smoothly over the top of the wing. That is just for changes in attitude about the lateral axis.

There are a surprisingly high number of people that don't understand that the turning of an airplane is caused (not by the control surfaces) but by the horizontal component of lift. The control surfaces just manipulate the attitude of the airplane about/around it axis.

So the answer is no.

To add a little extra info, the Angle of Attack=The difference in angle of the chord line of any given airfoil to the relative airflow, Angle of Incidence=The difference in angle of the chord line of an airfoil to the longitudinal center line of the fuselage.
