ABSTRACT:
A controlled opening shock parachute is made by dividing each gore of a cular parachute into two panels, an upper and a lower. The adjoining edges of the panels are of different lengths and left unjoined so an uneven slit is formed. During the parachute's opening sequence, air flows into the slits to open the upper panels. After the upper panels are inflated, air flows out of the slits as the lower panels open.
