Abstract

An airframe assembly for an unmanned aerial vehicle (UAV) is provided where the airframe assembly includes a top airframe assembly, a bottom airframe assembly, and a planar support frame disposed between the top and bottom airframe assemblies. The top and bottom airframe assemblies may form one or more rotor ducts disposed about one or more UAV propulsion motor mounts, respectively, where the rotor ducts are configured to protect rotating rotors disposed therein from physical damage caused by impact with environmental flight hazards. The airframe assembly may further include a heat sink thermally coupled to electronics of the UAV and disposed within the airframe assembly such that rotating blades in the rotor ducts cause air to be drawn from outside of inlet orifices of the top airframe assembly, through an airflow channel in which dissipation surfaces of the heat sink are disposed, and into a rotor duct via an airflow outlet.
