A main assisted reserve deployment (MARD) system is a skydiving safety device for parachute systems. While there are many variations, the operation and intended outcome for each is the same: open the reserve parachute container and extract the reserve parachute's deployment bag (and parachute) using the jettisoned main canopy.
The three-ring system is simple, inexpensive, reliable, and requires fewer operations than earlier parachute release systems while reducing the physical force needed. The large bottom ring is securely attached to the skydiver's harness, the middle ring is securely attached to the end of the parachute riser, and the small ring is securely ...
CYPRES II panel. In skydiving, an automatic activation device (AAD) is a dead man's switch consisting of an electronic-pyrotechnic or mechanical device that automatically activates the opening sequence of the main or reserve parachute container when the AAD is falling below a preset altitude and above a preset decent speed.
RSL - Reserve Static Line RSL Shackle, held, and part of RSL shown installed in the container and attached to the main canopy riser RSL ring. A reserve static line, occasionally called a Stevens Lanyard or Stevens Release, is a device that automatically opens the reserve parachute container when the main parachute is cut-away.
Cut-away is a skydiving term referring to disconnecting the main parachute from the harness-container in case of a malfunction in preparation for opening the reserve parachute. The 3-ring release system on parachutes allows a rapid cut-away in the event of an emergency. Cutaway is also the title of a 2000 action film about skydiving.
The device allows the rapid release of the skydiver's main parachute in the event of a malfunction. As of 2020, all sport skydiving equipment and some military systems employ the design. [3] He also invented the pull-out and throw-out pilot chute. [4] A pilot chute is a small parachute used to extract and deploy a main parachute.
The pull-out and throw-out pilot chutes are identical in construction; the difference is in their connection to the handle and the bridle, and in the way they are packed. With the pull-out system, the pilot chute is packed inside the container. The activation handle is attached to a lanyard, which in turn is attached to the closing pin.
Effectively, the jumper drags the parachute behind him, causing the upward-rushing wind to force open and inflate the canopy. The canopy should inflate and begin supporting the jumper within four seconds. In the unlikely event of a malfunction, students are taught how to cut away the main canopy and deploy the reserve chute.
