Abstract: A motor housing includes a core and a shell having an annular body. The annular body is configured to secure a stator of a motor therein. The annular body includes first and second ends defining first and second openings, respectively. The annular body defines a slot extending along a length of the annular body. The slot is coterminous with the first opening. The core is configured to be in registration with the shell. The core is configured to rotatably support a rotating assembly of the motor including an output shaft. The core includes a base portion, an annular ring, and a guide arm interconnecting the base portion and the annular ring. The core is in registration with the shell when the guide arm is received in the slot of the annular body of the shell to form an interlocking structure.

Abstract: A valve assembly for use with an unmanned aerial vehicle is provided and includes an inlet tube, a shuttle, a base plate, a screw assembly, and a spacer block. The shuttle is partially disposed within the inlet tube and is configured to be placed in a first position where the shuttle abuts the inlet tube and a second position where the outer surface is disposed in spaced relation to the inlet tube. The base plate extends between a first end portion that defines a cavity therein and a second end portion. The screw assembly is disposed within the cavity of the base plate and is coupled to a portion of the shuttle. The spacer block is interposed between the second end portion of the inlet tube and the first end portion of the base plate and is configured to maintain the inlet tube and the base plate in spaced relation.

Abstract: Aspects of the disclosure relate to batteries for use in the stratosphere, such as those employed on aerial vehicles. The battery may include an outer case structure, a thermal insulator such as foam arranged within the outer case structure, a battery management unit and a plurality of battery cells both arranged within the thermal insulator, and a heater arranged within the thermal insulator and around the battery cells. In some instances, the battery may also include a thermal reflector arranged between the heater and the thermal insulator, wherein a surface of the thermal reflector is arranged to reflect heat back towards ones of the plurality of battery cells. In some instances, the thermal insulator may include overlapping baffles to reduce an amount of air passing from the outer case and through the thermal insulator. In some instances, the outer case may include a plastic layer with a low emissivity coating.
