A suspension line assembly for a parachute may comprise a plurality of suspension lines bound together at a confluence, and a dampening riser coupled to the confluence, wherein the dampening riser comprises a first length in the stowed position and the dampening riser is configured to extend to a second length in a deployed position in response to a tensile force applied to the dampening riser.

A system for controlling a tension of a tether between an object and a load tethered to the object comprises magnetorheological (MR) fluid actuator unit(s) including at least one torque source and at least one MR fluid clutch apparatus coupled to the at least one torque source to receive torque from the at least one torque source, the MR fluid clutch apparatus controllable to transmit a variable amount of torque via an output of the MR fluid actuator unit. A tensioning member is connected to the output so as to be pulled by the output member upon actuation of the magnetorheological fluid clutch apparatus, a free end of the tensioning member adapted to exert a pulling action when being pulled by the output member. Sensor(s) provide information indicative of a relation between the object and the load tethered to the object. A controller controls the at least one MR fluid clutch apparatus in exerting the pulling action based on said information.

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.

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 rotary-wing aerodyne includes a motor, a structure supporting at least one passenger seat, and a rotor arranged above the structure and linked to the motor by a hollow transmission shaft. The transmission shaft is movable in rotation relative to the structure. The aerodyne also includes a hollow mast attached to the structure and extending through the transmission shaft, and a parachute arranged above the rotor. The parachute is attached to the mast and linked to the structure by means of a suspension element passing through the mast. The suspension element is produced from a multi-strand steel cord with a tensile strength of greater than 150 daN/mm.sup.2.

A carrier system for carrying out interception maneuvers of a loadbearing paraglider which has a glider having a trailing edge for carrying out the maneuver with at least one interception line is fixed to said edge includes at least one carried load unit, which is connected to the carrier system via a first, short load carrier belt and a second, longer load carrier belt. A carried load connected to the carried load unit is carried by way of the first, short load carrier belt. The trailing edge is adjusted to carry out the maneuver by the gravitational force of the carried load, in that the first, short load carrier belt is separated and the carried load is carried by way of the longer, second load carrier belt.

There is provided a safety apparatus that not only has excellent safety performance but also has improved ease of accommodation of an ejected object in a container, and is capable of securing diversity of attachment positions to an aerial vehicle as compared with a related art, and an aerial vehicle including the safety apparatus. The safety apparatus includes a pilot chute ejector 62 and a main parachute storage. The pilot chute ejector 62 includes an actuator 1, a push-up member 15 pushed up in one direction by the actuator 1, a pilot chute 16 pushed up while being supported by the push-up member 15, a bottomed cylindrical container 18 that accommodates the actuator 1, the push-up member 15, and the pilot chute 16, and a lid 21 having a fan-shaped cross section that closes an opening end of the container 18. The actuator 1 is fixed at a position shifted from a geometric center of the fan-shaped cross section on a bottom surface of the container 18 via a base 2.
