SNOW PLOWING VISIBILITY IMPROVED WITH TURNING VANES MOUNTED TO PLOWS-CABS
Water tunnel tests are being conducted to develop methods of improving driver visibility during snow plow operations. Plates on the back of trucks were found to create air turbulence and were removed from test vehicles. Present research is directed toward finding ways of angling the tailgates and designing streamlined box covers to deflect the air flow downward over the back of the trucks. A novel concept being investigated involves a concave turning vane mounted over and just behind the cab on a framework. This deflects the air flow down over the back of the truck. Also under development is a modified turning vane that can be mounted on the top edge of the plow blade, extending over the lip of the plow. Mounted at the correct angle, the vane will catch most of the snow spillover and deflect it down over the back of the plow onto the highway, improving the driver's visibility.
