摘要： 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.
摘要翻译： 提供了一种改进的枢轴灌溉塔系统。 该系统包括可操作地连接到水源，多个可移动塔，多个跨度和多个喷洒头的枢轴。 一个或多个倒置翼型件连接到枢轴灌溉系统或结合到枢轴灌溉系统的设计中，以响应于特定迎角处的相对风而产生向下的力和/或减小系统上的阻力。 该系统可以包括沿着大多数跨度的相对的倒置翼型对。 倒置的翼型件可以具有用于从顶面去除液体的装置。 倒置的翼型件可以刚性地和/或枢转地连接到可动塔和/或跨度。 倒置翼型件可以设计成具有高弯度和/或高外倾角。 倒置翼型件的数量可能在远离枢轴的距离处更大。
