    Abstract: An example method of manufacturing a wing includes providing a wing frame. The wing frame includes a primary spar, a drag spar, a plurality of transverse frame elements having at least one spar joiner, and a plurality of mounting elements. The primary spar is coupled to the drag spar via the at least one spar joiner. The method further includes placing the wing frame into a mold, wherein the mold defines a shape of the wing. The method also includes injecting the mold with an air-filled matrix material, such that the air-filled matrix material substantially encases the wing frame and fills the defined shape of the wing, and such that the plurality of transverse frame elements provide torsional rigidity to the wing.

    Abstract: A propulsion unit includes a motor rotor that spins about a central rotational axis, propeller blades each having a proximal base and a distal tip, and pivot mounts each coupling the proximal base of a corresponding one of the propeller blades to the motor rotor. The propeller blades each freely pivot at the proximal base about a corresponding offset pivoting axis that is substantially parallel to but offset from the central rotational axis of the motor rotor.

    Abstract: An energy dispersion plug for use in an unmanned aerial vehicle (UAV) includes a blunt head section, a wedge section, and a rim section. The blunt head section has an outer side for receiving an impact force and an inner side opposite the outer side. The wedge section has a base end and a distal end opposite the base end. The wedge section extends at the base end from the inner side of the blunt head section towards the distal end and the distal end has a smaller cross-sectional area than the base end. The wedge section is shaped and sized to fit into an open end of a hollow structural member of the UAV and to transfer impact energy incident upon the blunt head section into the hollow structural member to shatter the hollow structural member into fragments.

    Abstract: A propulsion unit includes a motor rotor, a clip-in base mount, a clip-in rotor cap, propeller mounts, and propeller blades. The motor rotor spins about a central rotational axis. The clip-in base mount is disposed on the motor rotor. The clip-in rotor cap is shaped to mate with and detachably clip into the clip-in base mount. The propeller mounts are attached to the clip-in rotor cap. The propeller blades each have a proximal base and a distal tip. The proximal base of each propeller blade mounts to a corresponding one of the propeller mounts.
