How Does An Aircraft Float In Air?

Aircraft in the forward movement, the air flow to the wing leading edge, divided into upper and lower stocks, flows through the performance of the wing flow lines, are convex, making the convergence of variable density flow lines, flow tubes (the two The flow near the wall of the pipe line as) thinning; while flowing through the lower surface of the flow line also affected by the impact of raised, but the lower surface of the bulge is significantly smaller than the upper surface, so relative to the upper surface is streamlined than the loose, coarse flow control. As the wing upper surface of the flow tube thinning, flow speed, pressure is smaller than the lower surface flow tube thick, slow flow, the pressure greater. So that the wing upper and lower surface of the pressure difference. The role of pressure on the wings of various aspect is the difference between the sum of wing lift.
