What's Up With Wings?

For years I have been interested in aviation, and I was curious to see if I could design an aircraft wing that could create more lift than what is common now. I also wanted to find out if there is a relationship between the design of a wing and the lift generated. To answer this, I built various wings and a wind tunnel. I attached the wings to a base and placed them on a scale in the wind tunnel, and tested how much weight was lifted on airspeeds of high, medium and low. I found that a roof design, with two boards at an obtuse angle, produced more lift than any of my curved designs. The designs with flaps in the front of the wings did not increase lift compared to the wings without frontal flaps, however I believe that perhaps if I decrease their size my results may have been higher, so I would like to conduct further testing to see if this is correct. My results suggest that both a wing with a rear flap and a wing that is concave on its underside will produce the greatest lift. I may also conclude that a wing with a thicker curvature does not necessarily produce more lift than one with a thinner curvature. Considering these deductions, wings on remote controlled planes may be given concaves or rear flaps to increase lift, thus allowing take-off areas to be shortened. To test further; one may test how the size of a flap, the drag of a wing, or the tilt of the wing (width wise) affects lift the lift that is generated.rnrn
