Abstract: An unmanned aerial vehicle according to certain embodiments generally includes a chassis, a power supply mounted to the chassis, a control system operable to receive power from the power supply, at least one rotor operable to generate lift under control of the control system, and a winch mounted to the chassis. The winch includes a reel and a motor. The reel has a line wound thereon, the line having a free end. The reel includes a circumferential channel in which a wound portion of the line is wound onto the reel. The circumferential channel includes an inner portion, an outer portion, and a passage connecting the inner portion and the outer portion. The motor is operable to rotate the reel under control of the control system to thereby cause the line to wind onto and off of the reel, thereby causing the free end of the line to raise and lower.

Abstract: The disclosure is directed in part to a thrust vectoring algorithm and/or thrust vectoring controller configured to allow for control of an aircraft with a plurality of tilting rotors. Thrust vectoring is a method of controlling the aircraft by pointing the motors in the direction you need thrust, as opposed to traditional methods of flight control surfaces which deflect airflow or tilting the entire body of the aircraft. The disclosed thrust vectoring algorithm and/or thrust vectoring controller allow for the control of VTOL aircraft with a plurality of tilting rotors.

Abstract: An airframe design may include a bonded frame or assembly, and one or more components (645) that may be removably attached to the bonded frame. The bonded frame may include struts (102), central bulkheads (106), a tail section, a plurality of wing sections, and motor mounts (650) that are adhered together using adhesive. The one or more attachable components (645) may include a forward fuselage (640), motors (756), propellers (860), motor pod fairings (862), stabilizer fins, and landing gear (972) that are attached using fasteners. The bonded frame may reduce the number of parts of the airframe design and may also reduce complexity, cost, and weight, while also increasing stiffness and strength. Further, the various attachable components (645) may facilitate fabrication, assembly, and maintenance of an aerial vehicle having the airframe design.

Abstract: The technology described herein relates to autonomous aerial vehicle technology and, more specifically, to autonomous unmanned aerial vehicle with folding collapsible arms. In some embodiments, a UAV including a central body, a plurality of rotor arms, and a plurality of hinge mechanisms is disclosed. The plurality of rotor arms each include a rotor unit at a distal end of the rotor arm. The rotor units are configured to provide propulsion for the UAV. The plurality of hinge mechanisms mechanically attach (or couple) proximal ends of the plurality of rotor arms to the central body. Each hinge mechanism is configured to rotate a respective rotor arm of the plurality of rotor arms about an axis of rotation that is at an oblique angle relative to a vertical median plane of the central body to transition between an extended state and a folded state.
