摘要： Disclosed is a package delivery mechanism for use by an unmanned aerial vehicle (UAV). The package delivery mechanism includes a gravity activated locking mechanism to lock and unlock a package attached to the UAV based on the weight of the package. When the package is attached to suspension means of the UAV that lowers the package to the ground from the UAV, the locking mechanism automatically engages with the package and keeps the package locked to the suspension means, due to the weight of the package. When the package is lowered and reaches on the ground, the weight of the package is offloaded from the suspension means, which enables the locking mechanism to be disengaged, thereby releasing the package. The package delivery mechanism includes a severing module to sever the suspension means from the UAV.

摘要： A shock absorber assembly, particularly for attenuating shocks transmitted to a person's body, especially to reduce shock to a paratrooper's body during a tethered cargo tandem jump. Specialized elastic absorber units are disposed between two connectors, such as carabiners, with a connector secured to a respective end of each absorber unit. Each absorber unit has a rupture length corresponding to its length when it is stretched to its maximum immediately before rupturing under tensile loading. A limiter strap also is secured between the connectors, with a connector on each end of the limiter strap. The limiter strap prevents the absorber units from breaking by preventing their stretch to their breaking point. A flap or bands are provided for temporarily maintaining the limiter strap folded in a compact bale until needed. In use, the complete shock absorber assembly is deployed between a cargo tether and a cargo harness.

摘要： A parachute release mechanism includes a housing, a strap hinge pin pivotably mounted to the housing, a cord coupled to the housing, and a cord tensioner coupled to the housing and coupled to the cord, wherein the cord tensioner is configured to impart a desired tension to the cord. The strap hinge pin is pivotable between a secured position and a released position, wherein in the secured position the strap hinge pin is configured to support a suspension strap for a payload and in the released position the suspension strap is enabled to disengage from the strap hinge pin. The cord is configured to retain the strap hinge pin in the secured position.

摘要： A parachute deployment system is disclosed. In various embodiments, the system includes an interface configured to receive sensor information; a parachute load limiting device; and a parachute load limiting device state controller. The parachute load limiting device state controller sets a state of the parachute load limiting device to a state associated with a corresponding amount of load based at least in part on the sensor information.

摘要： A ring release system is configured to releasably couple a parachute to a payload. The ring release system may comprise a series of release rings affixed to a riser. At least one release ring has an associated retaining ring that surrounds the riser and is affixed to the riser on a back side. The retaining ring prevents stitching securing the release ring from being placed in peel when under stress, improving the reliability of the ring release system.

摘要： A system and method for detaching an extractable unit from an extraction unit pulling the extractable unit in an extraction direction out of a cargo bay of an aerospace vehicle for aerial delivery. The system includes a detachment unit which is connectable to an extractable unit and which is operable for controllably detaching an extraction unit from the extractable unit, a guiding system and a release unit. The release unit is movably attached to the guiding system and physically connected to the detachment unit such that the release unit is movable with an extractable unit to which the detachment unit has been connected in the extraction direction along the guiding system. The release unit is controllable to operate the detachment unit to which the release unit is connected for detaching an extraction unit from the extractable unit.

摘要： Systems and methods for aerially delivering cargo into a body of water while avoiding parachute entrapment and entanglement are described. The system includes a parachute having a canopy and suspension lines. The system further includes a weight coupled to a first end of the suspension lines and a ring that is configured to float in the body of water. The weight is coupled to the cargo, and the ring is disposed between the weight and the canopy with the suspension lines passing through the center of the ring.

摘要： A quick release restraint system comprising a restraint body that mates a harness fitting with a moveable lockpin. The lockpin is held in a closed position by a return member and can be moved to an open position when a sleeve and/or a ripcord is moved away from the lockpin. The sleeve surrounds the restraint body and mates with an internal lockpin body that may also be attached to the ripcord. The ripcord and/or sleeve engage the lockpin body in a single direction to generate a pulling force that counteracts a biasing force of the return member.
