Decisive Roll of Filling Time on Classification of Parachute Types

摘要: In a low altitude recovery, parachute has to reduce the recovery mass velocity predefined before its ground impact within vertical distance as possible. The article classifies various parachutes based on opening shock and necessary satisfy steady descent condition in an unreefed situation using numerical solutions of experimental theoretical relations linked with flight dynamics. Results show that filling time is main parameter differentiate all from each other. Based time, slotted history coverage locates between ribbon ringsail parachutes, whereas solid textile span range extended skirt 14.3% guide surface parachutes. group, decrease result change type causes increase well distance.
