A system for deploying loads out of an aircraft comprises an aerial delivery parachute with an aerial-delivery parachute line and an activation means for placing the aerial delivery parachute in an enveloping flow past the aircraft. Within the aircraft a receiving device can be positioned that receives a tractive force acting on the aerial-delivery parachute line, which tractive force has been determined by a force measuring device and has been transmitted by way of a transmitting device. With the knowledge of the tractive force it is possible both to implement emergency release and to assess whether an aerial delivery parachute has correctly deployed in the flow enveloping the aircraft.

A canopy release assembly includes a base plate member and a pin assembly movably coupled to the base plate member. The pin assembly is configured to move to and from a locked state and an unlocked state. A cover is pivotally coupled to the base plate member and is configured to move to and from a closed state to an open state. A first release member has a first end coupled to the pin assembly and is configured to move the pin assembly to the unlocked state in the open state of the cover. A second release member is coupled to the cover and configured to engage the pin assembly in the closed state of the cover to move the pin assembly to the unlocked state.

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.

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.

A system is disclosed that includes an interface which receives sensor information associated with a vehicle, a severing tool, a parachute load limiting device state controller, and a reefing device. The controller determines, based at least in part on the sensor information, whether to instruct the severing tool to release a reefing device prior to parachute deployment. If it is determined to instruct the severing tool to release the reefing device prior to the parachute deployment, the severing tool is so instructed. If it is determined to not instruct the severing tool to release the reefing device prior to the parachute deployment, the reefing device is configured to be situated around a parachute canopy to constrain the parachute canopy during an initial state and slide down the parachute canopy to a position below the parachute canopy to constrain one or more parachute tethers.

A strap that may be used to secure equipment (e.g., a bag) to the parachute harness of a parachutist. The strap may provide adjustability of an effective strap length to assist in positioning the suspended equipment relative to the parachutist. The strap may include quick-release features that allow the suspended equipment to be quickly and easily disengaged (e.g., once the parachutist has landed). In turn, a transition to ground operations in which the equipment is in use may occur quickly and without heavy rigging or additional containers for stowing the equipment during the jump. In turn, the strap may be carried with the parachutist during ground operations without significant additional weight.

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.
