Airfoils on pivot irrigation tower systems
An improved pivot irrigation tower system is provided. The system includes a pivot operatively connected to a water source, a plurality of movable towers, a plurality of spans, and a plurality of sprinklers. One or more inverted airfoils are connected to, or incorporated into the design of, the pivot irrigation system to generate a downward force and/or to reduce drag on the system in response to the relative wind at a specific angle of attack. The system may include opposing pairs of inverted airfoils along a majority of the spans. The inverted airfoils may have means for removal of liquid from the top surfaces. The inverted airfoils may be rigidly and/or pivotally connected to the movable towers and/or the spans. The inverted airfoils may be designed with high camber and/or high camber angle. The quantity of the inverted airfoils may be greater at distances farther from the pivot.
