Structures of different DGB parachutes. (IMAGE) Beijing Institute of Technology Press Co., Ltd Caption Two ideas were adopted to optimize and improve the existing DGB parachute structure. One is to increase the drag coefficient. The disk part is thus modified to a structure with a higher drag coefficient, such as the hemisflo parachute structure and the triconical parachute structure. The other is to enlarge the band’s area to increase the parachute’s stability, such as adding a tapered band on the lower skirt of the canopy. The specific parachute structures are shown in the Figure.
