wing fence

The effect is the same as a wing fence.

The upper surface of the wings had two wing fences each side.

In front of the ailerons there are small wing fences.

Wing fences were added mid-wing to increase the lift characteristics.

It has swept wings with two wing fences on each wing.

Two wing fences were fitted on the upper surface of each wing.

The J-8Ds heavier airframe is used but with modified wing fences.

He introduced the concept of wing fences.

In this case the low-speed air flows towards the fuselage, which acts as a very large wing fence.

They can be used as an alternative to wing fences, which also restrict airflow along the span of the wing.

More recent aircraft have wingtip mounted winglets or wing fences to oppose the formation of vortices.

Vortilons only stream vortices at high angles of attack and produce less drag at higher speeds than wing fences.

Wing fences delay, or eliminate, this effect by preventing the spanwise flow from moving too far along the wing and gaining speed.

The swept wings were of very low taper (almost constant chord)with 1/2 span flaps/ailerons and two wing fences each side.

As a result, de Havilland re-profiled the wings' leading edge with a pronounced "droop", and wing fences were added to control spanwise flow.

After the wind tunnel tests, two wing fences were installed on a more advanced, longer version of the DFS-346, to correct the airstream separation.

The low wing had a 25-degree leading-edge sweep, a 3-degree dihedral from the roots, and low wing fences at midspan.

Wing fences, also known as boundary layer fences and potential fences are fixed aerodynamic devices attached to aircraft wings.

The Horton modifications include a drooped leading edge cuff, conical cambered wingtips, control surface gap seals and wing fences.

Washout may be accomplished by other means e.g. modified aerofoil section, vortex generators, leading edge wing fences, notches, or stall strips.

Various aerodynamic "fixes" to try and counter pitch-up effects at high speed and altitude included flared-out wingtips and wing fences.

The wing had two spars with two wing fences ranging the entire chord, with hydraulically operated ailerons and Fowler flaps.

Not to be confused with wingtip fences, wing fences are flat plates fixed to the upper surfaces (and often wrapping around the leading edge) parallel to the airflow.

A common solution to the problem of spanwise flow is the use of a wing fence or the related dogtooth notch on the leading edge of the wing.

These tests revealed a violent pitch-up tendency during high-speed turns, often as much as 6 g, and on one occasion 8 g. The addition of wing fences alleviated this problem.
