Systems and methods for delivering payloads are described. In some embodiments, a system may include a tether, a release wire, and a coupling. The system may have a first state and a second state. In the first state, a portion of the coupling may extend through an opening in the tether and engage the release wire. In the second state, the release wire may not engage the portion of the coupling such that the portion of the coupling can pass freely through the opening in the tether.

The present invention relates to a casing intended to be externally applied, connected or fixed to the fuselage or to a wing of an aircraft or to a central or wing station/hardpoint of an aircraft, the casing entirely or partly delimiting a housing zone (HZ) of a super-orbital, orbital or sub-orbital launch vehicle.

The location detection unit detects a destination location for delivery of an item by a drone. The release determination unit determines whether the drone transporting the item can release and place the item at the destination. Upon determination that the release and placement is not possible, a standby airspace determination unit determines a standby airspace within which the drone waits. The wait-time determination unit determines a wait-time for the drone in the determined standby airspace. The wait-time determination unit determines a wait-time by which the drone can arrive at a next destination by a scheduled arrival time following departure of the drone departs after standby. The standby instruction unit issues to the drone an instruction related to the standby.

An aircraft cargo hold unloading and collection system having an aircraft body, a lifting device, and a netted shelf. The lifting device is arranged on the aircraft body, and the lifting device is connected to the aircraft body through communication. The lifting device has a retractable cable. One end of the cable can be connected to the cargo hold, and the other end is fixed relative to the aircraft body. The netted shelf is used to be arranged on the ground, and the aircraft body is provided with a position identification part. The netted shelf is provided with a trigger part, and the position identification part can identify the signal transmitted from the trigger part to locate the netted shelf.

Delivery systems for aerial vehicles may provide a passive automatic delivery system that is automatically triggered during landing of the aerial vehicle. One or more arm assemblies of the delivery system may include a respective landing arm, resilient member, and package guide. The landing arm is configured to rotate in response to an applied external force, with the resilient member being operatively coupled to the landing arm and configured to bias the landing arm towards a resting position. The package delivery system automatically releases the package when a delivery condition is met, such as the landing arms of the delivery system being rotated past a threshold position. Delivery systems can thus passively and automatically ensure that all landing arms are on a landing surface before the package is released. Related methods include approaching and contacting a landing surface, and releasing the package at the landing surface of the delivery location.

A container for housing and launching sonar buoys of class G (sonobuoy) including a casing partitioned into two portions and automatic and simplified valve means to sequentially eject the buoys from the container.

A container for housing and launching sonar buoys of class G (sonobuoy) including a casing partitioned into two portions and automatic and simplified valve means to sequentially eject the buoys from the container.

Disclosed is a sonobuoy that houses at least one unmanned vehicle that may be launched from the sonobuoy. The sonobuoy may include a canister, a parachute, an unmanned vehicle, and a launch mechanism. The parachute may be disposed within an interior cavity of the canister proximate to a first end of the canister. The unmanned vehicle may be disposed within the interior cavity of the canister proximate to a second end of the canister. The launch mechanism may be disposed within the interior cavity of the canister and operatively coupled to the unmanned vehicle. The launch mechanism may be configured to launch the unmanned vehicle from the canister. The sonobuoy may further include a launch deployment mechanism that may be configured to orient the canister with respect to a surface after the sonobuoy impacts the surface in order to facilitate the launch of the unmanned vehicle.
