Nobody knew that wings could generate this kind of force.

Prior to rotation the wing generated almost no lift, unlike typical aircraft wings.

Without the use of these "high-lift" devices, the wings did not generate enough lift to keep the aircraft in the air.

When a wing generates aerodynamic lift the air on the top surface has lower pressure relative to the bottom surface.

The wings can only generate a finite amount of lift at a given air speed.

The denser the air, the more lift a wing will generate at any given speed.

However, it also means the wing cannot generate extra lift as easily, which is needed for maneuvering or flight at high altitudes.

But the right wing alone had generated the miscompare.

A treatment of why and how wings generate lift that focuses on pressure.

According to this analysis, published in the current issue of Nature, the bird's flapping wings generate both lift and thrust.
