Claim 0:
1. A drone comprising:
a housing that includes:
a first continuous surface that i) is substantially flat and ii) extends through a radial center of the housing;
a plurality of ducts that each extend from the first continuous surface to a second surface of the housing, 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;
an internal cavity at a location intermediate two respective ducts of the plurality of ducts; and
circuitry positioned in the internal cavity, wherein the circuitry is operable to generate control signals;

respective fan assemblies installed in each duct of the plurality of ducts, each respective fan assembly comprising a respective motor that is coupled to receive control signals from circuitry to generate a first air pressure at the first continuous surface and a second air pressure at the second surface when operating the respective fan assemblies, wherein the control signals generated by the circuitry are used to operate the respective fan assemblies,
wherein, when operating the respective fan assemblies, the first continuous surface being substantially flat cooperates with the rounded edge of the respective inlet of each duct of the plurality of ducts causing the first air pressure to be less than the second air pressure; and
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 an inner wall of the corresponding duct.
