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 system enabling safe manned and unmanned operations at extremely high altitudes (above 70,000 feet). The system utilizes a balloon launch system and parachute and/or parafoil recovery.

There are provided a safety apparatus and an aerial vehicle including the safety apparatus, in which a lid and an opening end of a container are fixed before operation more firmly than a conventional art to be less susceptible to an external environment. A safety apparatus includes a piston member 10, a cylinder 14 that accommodates the piston member 10 and is provided with a bore 13 through which the piston member 10 protrudes to the outside during operation, a push-up member 15 that is pushed up in one direction by the piston member 10, an ejected object 16 that is pushed up while being supported by the push-up member 15, and a gas generator 17 that moves the piston member 10 in the cylinder 14. A bottomed cylindrical portion 19 of the push-up member 15 has a hole 53, the hole 53 has a substantially identical shape to a shape of one end of a rod 12, and the one end of the rod 12 is fitted to the hole 53. The bottomed cylindrical portion 19 and the rod 12 are fastened and fixed by a bolt member 15.

There is provided a safety apparatus including a push-up member in which an ejected object is hardly displaced even during transportation, and an aerial vehicle including the safety apparatus. A safety apparatus 100 includes a cylinder 14 that accommodates a piston member 10 and is provided with a bore 13 through which the piston member 10 protrudes to the outside (upward in FIG. 1) during operation, a push-up member 15 that is pushed up in one direction by the piston member 10, an ejected object 16 that is pushed up while being supported by the push-up member 15, a gas generator 17 as a power source that moves the piston member 10 in the cylinder 14, a container 18 that has a bottomed cylindrical shape and accommodates the piston member 10, the cylinder 14, the push-up member 15, the ejected object 16, and the gas generator 17, and a lid 21 that closes an opening end of the container 18. A movement preventing member 27 that prevents the ejected object 16 from moving in a circumferential direction of a bottomed cylindrical portion 19 is provided on an upper surface of a support 20 of the push-up member 15.

Systems, devices, and methods including: a latching mechanism comprising: a first latch configured to attach to a door of an unmanned aerial vehicle (UAV); a second latch configured to attach to a portion of the UAV distal from the first latch; a string connected between the first and second latch, where the string secures the door shut; at least two radio modules in communication with a ground control station; and at least two burn wires in contact with a portion of the string between the first latch and the second latch; where current from a backup battery passes to at least one burn wire when the burn signal is received, where the burn wire causes the connection between the first latch and the second latch to be broken and the door of the UAV is separated from the UAV, and where the parachute is deployed when the door of the UAV is separated from a rest of the UAV.

A drogue bridle attachment assembly may comprise a housing, a lock pin, jackscrew gear pin, and a drive gear pin. The housing may define a bridle opening. The lock pin may be configured to translate into the bridle opening. The jackscrew gear pin may include a threaded portion and a gear portion. The threaded portion may engage a threaded opening in the lock pin. The drive gear pin may include a drive gear portion intermeshed with the gear portion of the jackscrew gear pin.

Methods of reducing wing type parachute opening shock during a parachute drop, and parachute systems with reduced opening shocks are disclosed, the opening force reduction is achieved by dynamic braking, i.e. dynamically adjusting the canopy control lines during the inflation stage of the canopy. Typically, the control lines are set to zero brake length when the parachute canopy is released from the deployment bag, and are at least shortened during the inflation stage, optionally all the way to full brake. Optionally the control lines are also lengthened prior to completion of the canopy inflation. Other features and parachute systems are also disclosed.
