同軸二層式落下傘
Document Type and Number:
Japanese Patent JP6413029
Kind Code:
B2
Abstract:
Disclosed is a coaxial two-layered parachute (10) comprising an inner layer of inflation sac body (20) and an outer layer of parachute cover (30) provided on a coaxial centreline, and a bearing article (T) connected below the inner layer of inflation sac body (20) and the outer layer of parachute cover (30), wherein helium gas is pre-filled inside the inner layer of inflation sac body (20) and generates a buoyancy (F), such that the inner layer of inflation sac body (20) floats upwards to a suitable height due to the internal buoyancy (F), and when the inner layer of inflation sac body (20) floats upwards to a suitable height and when the bearing article (T) connected below the inner layer of inflation sac body (20) and the outer layer of parachute cover (30) falls, taking advantage of an upward current of outside air, the air current enters an inflation space (31) through an air inlet of the outer layer of parachute cover (30) to form another buoyancy (F1), resulting in a completely open parachute state due to the air current entering the inside of the inflation space (31) of the outer layer of parachute cover (30).
