Abstract
A reduced noise curved surface, including the elements of a curved substrate and a plurality of micropillars operationally connected to the curved substrate and defining a coating, wherein the respective micropillars are positioned to define an aperiodic sequence based on the golden ratio, and wherein the plurality of aperiodically sequenced micropillars increase sound absorption and drag reduction of the curved surface.
