Explore: Sharp Leading Edges

as for a flat plate, the leading edge is also sharp, then vortices also shed at the leading edge and the role of leading edge vortices is two-fold: 1)

normal flight to minimize drag. A dogtooth is a small, sharp zig-zag break in the leading edge of a wing. It is usually used on a swept wing, to generate

of lift due to the action of leading edge vortices. It is generated by wings with highly sweptback, sharp, leading edges (beyond 50 degrees of sweep)

leading-edge cuff is a wing leading-edge modification, usually a lightly drooped outboard leading-edge extension. In most cases of outboard leading-edge

rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. The air

design problems. The first design flaw was that Y-8 wings have very sharp leading edges, so one wing tends to stall before the other, causing the aircraft

and to test surfaces for relative sharpness. Some materials in the environment naturally break with extremely fine edges. A notable example is obsidian,

elements common to stealth engineering, such as zigzag edged landing gear doors and sharp leading edges, and the exhaust is not shielded by the wing. Aviation
