A device (1) is described for braking the fall of a load comprising a sling (2) and a braking element (3, 30), said sling (2) comprising a first end (21) constrainable to an anchoring point; a second end (22) constrainable to said load; a folded section (23) comprising a first portion (23a) of said sling (2) reversibly joined to a second portion (23b) of said sling (2), said folded section (23) providing a resistance to the separation of said first and second portions (23a, 23b). The sling further comprises a first free section (24) comprised between said first portion (23a) of said folded section (23) and said first end (21); and a second free section (25) comprised between said second portion (23b) of said folded section (23) and said second end (22). The braking element (3, 30) comprises a plurality of passages for said sling (2), said first free section (24) crossing at least one first passage (3a), said second free section (25) crossing at least one second passage (3b), so that said first portion (23a), as a consequence of the application of a traction force (FT, FT) higher than a threshold value to at least one of said two ends (21, 22), separates from said second portion (23b) and crosses said first passage (3a), and said second portion 23b crosses said second passage (3b).

A parachute is coupled to a rocket where the parachute is extracted by having the rocket pull on the parachute. A parachute strap couples the parachute to an aircraft where at a first point in time, a first section of the parachute strap and a second section of the parachute strap are both secured independently of each other. At a second point in time, the second section of the parachute strap is still secured while the first section of the parachute strap is released where the released first section of the parachute strap gradually becomes taut as the parachute is extracted.

An assembly for use with an aerodynamic decelerator for an aerial vehicle, such as a parachute, the assembly having a lead line with a first end and a second end, with the first end structured for attachment to the aerial vehicle, and an energy absorbing assembly having a first end attached to the second end of the shock cord and a second end structured for attachment to the parachute, the energy absorbing assembly in one implementation including an elongate flexible filament having first and second ends attached, the first end attached to the lead line and the second end attached to a decelerator. The first and second ends are attached to each other with rip-stitching, the first and second ends structured to break apart from each other in response to a load exerted by deployment of the parachute.

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 in series in connection with a tether or strap to maintain the series configuration. A chain reactive shock absorption can be predetermined, and adjusted based on the expected shock(s) of a given jump. The adjustment is accomplished by selecting the number and type of absorber unit(s) provided an any of two (or more) series chains of the assembly. In use, the complete shock absorber assembly is deployed between a cargo tether and a cargo harness.

A shock load attenuation device is provided. The shock load attenuation device includes a crushable material; a first compartment in the crushable material surrounding a first line; and a second compartment in the crushable material surrounding a second line. In response to the first line being acted upon by a first force and the second line being acted upon by a second force, a first loop in the first line is configured to slide along the second line and a first loop in the second line is configured to slide along the first line, crushing the crushable material.
