A linear cavity is provided on the leading edge of an object that is subject to the flow of liquids or gasses, where said cavity preferably has a wall that follows the curvature of a diminishing sine wave, although other configurations are possible that do not follow a specific sine wave. The cavity accepts the flow of liquids or gasses that enter into the cavity, and where the dimensions of the cavity cause the flow of liquids or gases within it to form a pressure node that extends forward of the cavity. The pressure node provides a wedge means to cause...
I claim: 1. A leading edge, where said leading edge defines a linear structure said leading edge comprises a primary cavity extending along the entire length of the leading edge, said primary cavity defined by a first mouth comprising an upper and lower lip opening onto the leading edge and a first inner side wall; said primary cavity has a depth or width that exceeds the width of the first mouth; said first inner side wall comprises a second mouth defined on the back rear side; said second mouth leads to a secondary cavity having a second inner sidewal...
