Embodiment Construction

[0021] Modern unmanned sensor platforms, such as unmanned aerial vehicles (UAVs), are capable of operating over long distances and in a variety of environments. The present disclosure provides systems and methods related to UAV architectures that contribute to aircraft safety and durability when traversing confined areas of such environments, while also providing UAVs with increased propulsion efficiency. The UAV architecture also allows the UAV to land and take off upside down, and the UAV architecture can be buoyant enough to allow the UAV to float on water. For example, when the UAV is floating on water, rotors disposed within the rotor ducts of the UAV architecture may be positioned substantially above the water to allow takeoff from the relatively dry rotors afloat. In other embodiments, the UAV architecture may have sufficient buoyancy to allow the UAV to float, but the rotors may be partially or fully submerged. In this case, the UAV could be configured to operate the ...

Abstract

A fuselage assembly for an unmanned aerial vehicle (UAV) is provided that includes a top fuselage assembly, a bottom fuselage assembly, and a planar support frame disposed therebetween. The top fuselage assembly and the bottom fuselage assembly may form one or more rotor ducts disposed about the one or more UAV propulsion motor seats, respectively, where the rotor ducts are configured to protect rotating rotors disposed therein from physical damage caused by impacts that are dangerous to fly from the environment. The fuselage assembly may also include a heat sink thermally coupled to the electronics of the UAV and disposed within the fuselage assembly such that rotating blades in the rotor duct draw air from outside the inlet aperture of the top fuselage assembly, through the airflow channel of the dissipative surface in which the heat sink is disposed, and into the rotor duct via the airflow outlet.
