There's a lot of talk in the automotive world about rear wings and rear spoilers. Between the two, there is actually a ...

The bags also provided a smooth contour to blend the wings’ trailing edges and the aft fuselage, allowing a smooth flow of air. Each wing had a hydraulic motor that moved it either forward or aft.

In theory, keeping the flow of air over a wing laminar, that is, smooth and free of even very small-scale turbulence, could halve the drag. In practice, like the elliptical planform, laminar ...

When a race car’s wing is tilted at an angle (1), the air on the bottom will detach from the surface, creating turbulence ...

As the bird moves forward, the curved upper surface causes the air to flow faster over the top of the wing, creating lift. So even when the bird glides or soars, the wing shape helps keep it up in ...

This shape allows air to flow through the slot between the mainplane and the second element, improving the local downforce generated by the front wing in this area. For what concerns the shape of ...
