How is the wing lift generated?

1904 Russian scientist Jukovsky ( Nikolai zhukovsky1847-1921 A modern wing theory was created to illustrate the reason for the wing to generate lift in flight and to give a rigorous proof in mathematics. Since then, people have a scientific concept of the wing. Scientists are not businessmen who have created The great achievements of humanity in the past century.

say the truth, Sunshine Power 2 The solar plane is actually a pair of artificial "big wings", in the wind tunnel experiment to make its lift-drag ratio and glide ratio to maximize. I am sure that Jukovsky's soul will bless it and fly peacefully to the Pacific.

In layman's words, the air pressure on the wing surface is related to the atmospheric density of the surface. In a relatively stationary wing, the upper and lower surfaces of the wing have equal atmospheric density, no pressure difference and no "lift". However, when the wing is in motion, the situation is different.

The upper surface of the wing is slightly raised, while the lower surface is basically flat. When the same mass of air flows through the upper and lower surfaces, the distance required to pass varies. From the elderly, the air density is relatively sparse, conversely, the air density is relatively dense. As a result, the upper and lower sides of the wing pressure difference, resulting in the so-called "lift."

The above description is just a simple "analysis", point out some "ideas" only, can not count. Watch the big solar plane, the eyes to the aircraft's big wings of the structure and shape (to see "doorway"), the others are "small things."

I think that the sun power 2 No , the solar plane won't have 3 the number. Flying across the Pacific is gone, and we really say good-bye. Alack!
