What is the advantage of the new upswept wing tips on passenger jets?
I am not sure about the date the wing tips were upturned on passenger jets. A lot has to do with Howard Huges’ development of his “Spruce Goose”, and not long after its formation, the research of Pan American American airlines for its ‘space business transport’, as seen in the 1960’s movie “2001: A Space Odessy. The whole thing has to do with flight. The aielerons on the rear of the wing alter the shape of the wing made of very thin metal. This results in the change in wind speed. A faster wind on the top of wing,compared to the slower, not altered (by much) speed of the wind on the bottom of the wing, creates a vacuum on top of the wing. The slower air pushes the wing–the plane–up into that vaccuum, to fill the space. The main problem, though, is stability. The vertical tips steady the plane against the wind forces by providing a shape that causes a minimum amount of drag on the plane. In later jet designs these too are controlled by ailerons, thus giving even more stability to the
