It was designed as … WebNext, case 2 (Fig. 1b) simulates a traditional and actual DGB parachute. However, in case 2, suspension lines between the disk and band are omitted because they are extremely thin (please see Refs. [6,10] for their influences). Thus, the gap in case 2 is continu-ous. This is the main difference between case 1 and case 2.
