Claim 13:
14. A method of manufacturing a drone comprising:
providing a housing with a first continuous surface, a second surface, and a sidewall between the first continuous surface and the second surface, the first continuous surface extending through a radial center of the housing that circumscribes the drone;
forming a plurality of ducts in the housing, each duct of the plurality of ducts corresponding to a respective hole that extends from the first continuous surface to the second surface, each duct of the plurality of ducts having a respective inlet that includes a rounded edge between an inner wall of the duct and the first continuous surface, each respective inlet of the plurality of ducts forms a merged air inlet that causes a reduction in a static pressure of air at the first continuous surface that flows into the merged air inlet;
installing, in each of the plurality of ducts, a respective fan assembly;
forming an internal cavity at a location intermediate two respective ducts;
forming a respective stator vane in each of the plurality of ducts, wherein the respective stator vane is secured in a corresponding duct by way of attachment to the inner wall of the corresponding duct;
connecting circuitry positioned in the internal cavity to the fan assembly, wherein the circuitry is operable to generate controls signals for operating the fan assembly; and
causing the first continuous surface to be substantially flat such that a first, low air pressure is generated at the first continuous surface and a second, high air pressure is generated at the second surface when each respective fan assembly is operated in correspondence to the first continuous surface being substantially flat and the respective inlet that includes the rounded edge between the inner wall of the respective duct and the first continuous surface.
