Description

Technical Field

[0002] A parachute-assisted descent mechanism is a technical device used to improve landing safety, reduce descent speed, and decrease the impact force on the ground. The parachute's function is to slow the falling speed of an object by increasing air resistance, preventing it from experiencing excessive impact during descent. However, parachutes themselves present certain technical challenges, especially in various complex environmental conditions, such as ensuring effective deployment and smooth control of the descent process.

[0003] Patent publication number CN203064202U discloses a parachute comprising eight independent canopies and sixteen parachute lines. Each canopy has two parachute lines. The canopies are double-layered with a middle layer to accommodate smaller items. The canopies are connected to each other via zippers to form the main parachute body. When opened, the main parachute body can be disassembled into smaller canopies, which can then be reused as packages for carrying rescue supplies. Each canopy is a different color, allowing for differentiation of the types of rescue supplies carried within.
