I don't see what a change in air density (such as taking the extreme case of a vacuum) has to do with lift. I'm going to build a thick wing, real thick! About 10,000 feet thick. While the bottom surface of the wing sits at 29.92" sea level atmospheric pressure, the upper surface will be *way* up there, in a lower-pressure area. This airplane is gonna to lift off the ground at zero airspeed with no power. |
