A parachute system having a parachute canopy having a skirt, and a plurality of gores spaced about the skirt. The plurality of gores is defined by first and second groups of gores. The parachute system includes a slider having a plurality of through-holes, a line loop attached to the slider, a first reefing line extending through the first group of gores and having a pair of ends attached to the line loop, and a second reefing line extending through the second group of gores and having a pair of ends attached to the line loop. A corresponding group of suspension lines passes through a corresponding through-hole in the slider. Each suspension line in each group of suspension lines is attached to a corresponding gore. A single reefing line cutter is engaged with the line loop and configured to cut the line loop after a predetermined amount of time has elapsed so as to release the reefing lines and allow the slider to slide down the suspension lines.

What is claimed is: 1. A parachute, for controlling its opening, comprising: a canopy having a skirt; a plurality of gores spaced about the skirt, the plurality of gores being defined by a first group of gores and a second group of gores; a slider having a plurality of through-holes, said slider be
What is claimed is: 1. A parachute, for controlling its opening, comprising: a canopy having a skirt; a plurality of gores spaced about the skirt, the plurality of gores being defined by a first group of gores and a second group of gores; a slider having a plurality of through-holes, said slider being positioned and fixed at the canopy skirt for impeding inlet airflow to the canopy and for slowing the opening of the canopy, said airflow around the slider being uniform; a line loop attached to the slider; a first reefing line extending through the first group of gores and having a pair of ends attached to the line loop, said first reefing line being connected to the slider; a second reefing line extending through the second group of gores and having a pair of ends attached to the line loop, said second reefing line being connected to the slider; a plurality of groups of suspension lines, each group of suspension lines passing through a corresponding through-hole in the slider, each suspension line in each group of suspension lines being attached to a corresponding gore; and a single reefing line cutter, said cutter being attached to the slider, and said line loop going through the reefing line cutter, said cutter being configured to cut the line loop after a predetermined amount of time has elapsed so as to release said first and second reefing lines and said slider, and to allow the slider to slide down the suspension lines, whereby said single cutter reefs the canopy by releasing both reefing lines and the slide, and said single cutter controls opening the canopy by allowing the canopy to start to inflate and expand, and thereby allowing the slider to slide down the suspension lines for further opening the canopy. 2. The parachute system according to claim 1 wherein the slider is generally symmetrical in shape. 3. The parachute system according to claim 1 wherein the quantity of through-holes in the slider is dependent on the quantity of groups of suspension lines. 4. The parachute system according to claim 1 wherein the line loop is generally centrally located on the slider. 5. The parachute system according to claim 1 wherein the plurality of gores comprises sixteen gores, the first and second group of gores each comprising eight gores. 6. The parachute system according to claim 1 wherein the plurality of groups of suspension lines comprises four groups of suspension lines. 7. The parachute system according to claim 6 wherein each group of suspension lines comprises four suspension lines. 8. The parachute system according to claim 1 wherein the plurality of through-holes comprises four through-holes. 9. The parachute system according to claim 1 wherein the slider has a generally square shape. 10. The parachute system according to claim 1 wherein the slider has a generally circular shape. 11. The parachute system according to claim 1 wherein the single reefing line cutter comprises a pyrotechnic reefing line cutter. 12. The parachute system according to claim 1 further comprising means for attaching the suspension lines to a payload. 13. A device for controlling the opening process of a parachute, having a canopy including a skirt, comprising: a slider having a plurality of through-holes for the passage therethrough of suspension lines, said slider being positioned and fixed at the canopy skirt; a line loop attached to the slider; first and second reefing lines attached to the line loop, and said reefing lines being connected to the slider; and a single reefing line cutter attached to the slider, said line loop going through the cutter, the cutter being configured to cut the line loop after a predetermined amount of time has elapsed for releasing the reefing lines and the slider, and allowing the slider to slide down the suspension lines, said released reefing lines allowing the canopy to inflate and expand, and said released slider sliding down the suspension lines for further opening the canopy. 14. The parachute system according to claim 13 wherein the loop is generally centrally located on the slider. 15. The parachute system according to claim 13 wherein the single reefing line cutter is generally centrally located on the slider. 16. The parachute system according to claim 13 wherein the plurality of through-holes in the slider comprises four through-holes. 17. The parachute system according to claim 13 wherein the slider has a generally square shape, the plurality of through-holes being equidistantly spaced apart. 18. The parachute system according to claim 13 wherein the single reefing line cutter comprises a pyrotechnic cutting device.
