A system for delivering and activating a two-part explosive may include an unmanned vehicle and/or an elevated structure, and a two-part explosive device. The device may include a container that is attached to, and releasable from, the unmanned vehicle or elevated structure. The container may contain an unsensitized explosive enclosed in a casing and and a sensitizing agent adjacent to the casing. The device may include an opening mechanism positioned at least partially within the container and adjacent to the casing. The opening mechanism may open the casing and expose the unsensitized explosive to the sensitizing agent, forming the two-part explosive in response to the container being released from the unmanned vehicle or elevated structure. The device may include a detonator inside or attached to the container. The detonator may trigger ignition of the two-part explosive after the unsensitized explosive is exposed to the sensitizing agent.

A pneumatic delivery system is used to facilitate delivery of canisters comprising delivery payloads by unmanned systems, such as unmanned aerial vehicles (UAVs). The pneumatic delivery system comprises a tube having a channel within a tube wall, where a canister is configured to move through the tube. The tube comprises a tube opening and a transfer mechanism proximate the tube opening. The transfer mechanism engages a canister having a payload that is moved within the tube. The transfer mechanism moves the canister through the tube opening by extending from a first transfer position to a second transfer position. At the second transfer position, the transfer mechanism orients the tube and releases it to a UAV for delivery.

A landing gear system that can be used with unmanned aerial vehicles (UAVs) retrieves and releases canisters suitable for delivering items. To do so, the landing gear comprises a first leg and a second leg. The first landing leg and the second landing leg are rotationally engages at a first leg connection end and a second leg connection end. A tensioning member applies a rotational force about the engagement location, biasing the first leg toward the second leg. Each of the first and second legs can include a curved portion. A UAV comprising the landing gear can be lowered over a canister, and the canister is secured in place within the curved portions of the legs. To release, the landing legs are rotated against the bias, which can be facilitated by landing the UAV and placing the rotors into a reverse thrust.

Techniques for using an unmanned aerial vehicle (UAV) to deliver a payload may be provided. For example, upon arrival to a delivery location, the UAV may release the payload and lower a tether coupling the payload to the UAV. Based on a distance associated with the lowering of the payload, the UAV may release the cable. This release may decouple the payload and at a least a portion of the cable from the UAV, thereby delivering the payload at the delivery location.

Landing gear, aspects of which are usable by an unmanned aerial vehicle (UAV), comprises a first leg with a first leg landing end and a first leg connection end, and a second leg with a second leg landing end and a second leg connection end. The first leg connection end is directly coupled to the second leg connection end at an engagement location. A tensioning member applies a rotational force about the engagement location, biasing the first leg landing end in the direction of the second leg landing end. The first leg and the second leg are configured to rotate against the rotational force when a downward force is applied to the engagement location.
