Hello. I've just been curious as to the answer to this question. Modern aerofoils are fine due to the geometry that allows for a pressure difference between the upper/lower surface. But as I remember WWI planes, they all have 4-5 levels of straight wings. Does that serve the same purpose? How? I tried googling it but couldn't sort through the irrelevant topics. I'd appreciate anyone who can feed my curiosity!
