Abstract: An example UAV landing structure includes a landing platform for a UAV, a cavity within the landing platform, and a track that runs along the landing platform and at least a part of the cavity. The UAV may include a winch system that includes a tether that may be coupled to a payload. Furthermore, the cavity may be aligned over a predetermined target location. The cavity may be sized to allow the winch system to pass a tethered payload through the cavity. The track may guide the UAV to a docked position over the cavity as the UAV moves along the landing platform. When the UAV is in the docked position, a payload may be loaded to or unloaded from the UAV through the cavity.

Abstract: A payload retrieval apparatus is provided including a channel having a first end and a second end provided with a curved portion, wherein the channel has a tether slot therein and is configured to receive a payload retriever attached to a tether suspended from a UAV; and a payload holder positioned at the second end of the channel on the curved portion, wherein the payload holder is adapted to hold a payload having a handle with an opening therein, wherein the curved portion is configured to change an exit angle of the payload retriever such that a lip of the payload retriever is angled upwardly to ease entry of the lip into the opening of the handle of the payload.

Abstract: A payload loading system is disclosed. The payload loading system includes a UAV and a loading structure. A retractable tether is coupled to a payload coupling apparatus at a distal end and the UAV at a proximate end. A payload is loaded to the UAV by coupling the payload to the payload coupling apparatus. The loading structure of the payload loading system includes a landing platform and a tether guide. The tether guide is coupled to the landing platform and directs the tether as the UAV approaches and travels across at least a portion of the landing platform such that the payload coupling apparatus arrives at a target location. The payload is loaded to the payload coupling apparatus while the payload coupling apparatus is within the target location.

Abstract: An example embodiment includes a landing pad having a housing and a power terminal configured to draw electric power from a power source. The landing pad further includes an electrically conductive landing terminal dorsal to the housing and configured such that, during a landing state of an aerial vehicle, the landing terminal makes contact with a plurality of electric contacts disposed ventrally to a fuselage of the aerial vehicle. The landing terminal is configured to transfer electric power drawn by the power terminal to the aerial vehicle via the electric contacts during the landing state of the aerial vehicle.
