does anybody know which side of the wing gets the lift. Mark, Both sides are necessary. Single surface winds, only found in Ultralights now I think, are much less effective in creating life, and they create more drag too. There's basically two theories about life creation, both of which describe part of what's happening. Bernoulli's theory says that air speeded up lowers it's pressure. I.e. there's a fixed amount of energy at any given time. It either goes into speed or pressure. The low pressure air is on the top of the wing. Yes, I'm simplifying greatly, there are much more detailed analysis available online and in aeronautical engineering books. The air from the top also is accelerated down after the wing passes due to the shape of the wing and the air following it. The other theory is that the air bounces off the bottom of the wing to push the wing up. (I'm cringing as I write this as I'm simplifying and dropping out so much). The air also follows this surface and also can be accelerated down as above. Basically, the wing works by having a shape that pushes air down, and thus the wing up. It does this with both the bottom and the top of the wing. Both surfaces are necessary and have different shapes for different speed airplanes. There's a picture I remember of a small jet flying just above a cloud layer in clear air. The air pushed downward was very visible as it caused an airplane-width trough in the cloud layer below. This is a topic which comes up regularly in this group. Most are tired of it and simply refer you to other sources as there's plent of information out there. One source I like is: http://www.av8n.com/how/. Libraries are useful too. -Malcolm Teas |
