ABSTRACT:
A parachute system has a canopy, suspension lines that extend from the canopy skirt to a confluence point, and a center line that is attached to and between the apex of the canopy and the confluence point. A single reefing line cutter is attached to the center line and is activated after a predetermined amount of time has elapsed. A first reefing line extends through a first group of reefing rings wherein one end of the first reefing line is attached to the single reefing line cutter and the opposite end is attached to the canopy skirt at a first predetermined location. A second reefing line extends through a second group of reefing rings that is opposite the first group of reefing rings. The second reefing line has one end attached to the single reefing line cutter and an opposite end attached to the canopy skirt at a second predetermined location that is across from the first predetermined location. The canopy opens to an initial circumference that is determined by the summation of the lengths of the first and second reefing lines. When the reefing line cutter is activated, the reefing line cutter releases the first and second reefing lines so as to allow full inflation of the canopy.
