An unmanned aerial vehicle (UAV) includes a fuselage, a pair of wings attached to the fuselage, and a propulsion system mounted to the wings to provide propulsion to the UAV. The fuselage has an outer fuselage shell that is a first mechanical support structure for an airframe of the UAV. The pair of wings is attached to the fuselage and shaped to provide aerodynamic lift. The wings have outer wing shells that are second mechanical support structures for the airframe. The outer fuselage shell or the outer wing shells comprise one or more formed-metal sheets.

UNMANNED AERIAL VEHICLE FUSELAGE

Implementations of an unmanned aerial vehicle (UAV) fuselage are provided. In some implementations, the fuselage comprises a frame having a shell removably secured thereto. The frame of the fuselage is made of printed circuit board (PCB) material that includes conductive tracks configured to conductively connect electrical components of the UAV. Due to the inherent rigidity of PCB material, the transfer of vibration loads to electrical components secured to the frame of the fuselage is minimized. While the shell is secured to the frame, an enclosure for any electrical components on the topside of the frame is formed. In this way, the encased electrical components may be protected from the environment (e.g., rain) and direct impact during a crash. In some implementations, the frame of the UAV fuselage may include a plurality of stiffening inserts that are positioned and configured to increase the rigidity of the frame.
