Noise-suppressing strut support system for an unmanned aerial vehicle

摘要

A strut support system for a ducted fan unmanned aerial vehicle (12) to suppress noise comprising: a ducted fan fuselage (14) that defines an opening (42); an engine that extends longitudinally through the opening in the fuselage; a drive mechanism rotatably mounted to the engine, wherein a fan is mounted on the drive mechanism within a duct defined by the opening; and a plurality of struts (18) extending between the ducted fan fuselage and the engine each comprising a first leg (20) and a second leg (22) joined together by a curvilinear junction (24), wherein the first leg is attached to the ducted fan fuselage and the second leg is attached to the engine, wherein the plurality of struts are positioned upstream of the fan, wherein the junction between the first leg of each of the plurality of struts and the ducted fan fuselage is outside the highlight (26) of the ducted fan fuselage's leading edge (28).
