WINDSOCK REPLACEMENT

The patented pivotal harness rotates without the aid of ball bearings or other devices The Glide Plate rotates 360 degrees within the Glide Collar by wind force alone. This is important because there is no added friction to artificially slow down or force to create a spin effect. The flag lifts the Glide Plate from the surface of the collar and rotates with a minimal amount of surface contact. There are no mechanical parts to jam or wear out.

The harness cords allow the side-to-side tilting motion of the flag which not only detects wind shear and variability of direction, but also creates an animation, and visual recognition of wind variability at a glance.

ORDINARY WINDSOCKS OBSOLETE:

The windsock design, or use, is not notably recorded prior to the late 1800's. It appears the sock was adapted from the "Wind-Sail" a wide tube or funnel of canvas used to convey a stream of air into the lower compartments of a ship (Noah Webster Dictionary 1828). The windsocks final fundamental use and design was later developed for use with small aircraft.

Ordinary windsocks cannot accurately indicate wind direction & speed because a volume of air in combination with sufficient wind speed must be realized before the open ended tube is filled and lifted. At that point, the air volume, and wind force in the tube is in direct conflict with any wind directional changes and acting against the sides of the tube. This deficiency in design limits its accuracy and ability to immediately respond to directional changes in the wind at lower speeds. This makes the ordinary airport windsock unsuitable for detection of low wind movement of hazardous airborne materials.
