What are wingtip fences?

A wingtip fence refers to the winglets including surfaces extending both above and below the wingtip, as described in Whitcomb’s early research. Both surfaces are shorter than or equivalent to a winglet possessing similar aerodynamic benefits. The Airbus A310-300 was the first airliner with wingtip fences in 1985.

What is the stall fence?

Stall fences are small chordwise plates that protrude from the upper wing surface and leading edge. Their purpose is to disrupt spanwise flow, shielding the outboard wing section from a developing inboard stall. By keeping the outboard section from stalling, aileron effectiveness is maintained during a stall.

What is the purpose of winglets on an airplane?

Winglets are vertical extensions of wingtips that improve an aircraft’s fuel efficiency and cruising range. Designed as small airfoils, winglets reduce the aerodynamic drag associated with vortices that develop at the wingtips as the airplane moves through the air.

What do the wing tips do on an airplane?

Winglets help mitigate the effects of “induced drag.” When an aircraft is in flight, the air pressure on top of the wing is lower than the air pressure under the wing. Near the wing tips, the high-pressure air under the wing rushes to the lower-pressure areas on top, which results in the creation of vortices.

What do wing fences do?

Wing fences, also known as boundary layer fences and potential fences are fixed aerodynamic devices attached to aircraft wings. As a swept-wing aircraft slows toward the stall speed of the wing, the angle of the leading edge forces some of the airflow sidewise, toward the wing tip.

What are wingtips?

Wingtip shoes are a classic look in menswear. They are characterized by a leather overlay on the toe that makes a W shape (or a wing shape). Over the years they have been a popular style of shoe, but they’ve got a long and convoluted history.

What is a wing fence residential?

Side boundary fencing must terminate and return to the dwelling at least 1.0m behind the front building line. This part of the fence that returns to the house is known as a wing fence. Fencing constructed along the side boundary forward of the dwelling or along the front boundary is not encouraged.

How do wing fences work?

How do wings work on a plane?

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.
