摘要

An energy absorbing device provided at the parachute riser strap of an aircraft, UAV, etc., adapted to reduce the otherwise high forces resulting from the weight of the aircraft, the speed of descent and, ultimately, the speed of impact, activated by the pilot or by means of the photoelectric cell attached underneath the aircraft measuring the distance from the ground.
