Abstract
In one or more embodiments, a fan assembly may comprise a fan hub with a plurality of blades, each blade having one or more cutouts through which laminar airflow from a front side of the blade can pass through the blade to a back side of the blade, reducing aeroacoustic noise. A cutout may be a lateral cutout, wherein the lateral cutout connects to an edge of a blade, or may be an internal cutout, wherein an internal cutout may be formed relative to a midline of the blade but does not connect to either edge of the blade.
