Winglets
are little, nearly vertical extensions of the wing tip. Their normal
use is, to stop the high-pressure air under the wing from coming to
the low pressure area over the wing and by this creating wingtip
vortices. Wingtip vortices are circular patterns of rotating air
behind the wingtip, and create big amounts of drag, called induced
drag. So the winglets are there to reduce this drag and by this
reduce fuel-consumption.
But we also thought, because our “wing”
isn't that wide the air coming from the high pressure to the low
pressure are would higher the low pressure quite a bit and decrease
by this the amount of lift essential.
First we didn't really know how we could do it, but soon we got the idea to just attach aluminium from a pop can to the sides. It tool us several hours to cut and attach them, but finally we had it and it worked. Also it worked very well, better than we thought in the beginning. As you can see in the recorded Data, it increased the amount of lift created by the wing by up to 50%.
