Abstract: A coaxial double layer parachute includes an inner inflatable body and an outer canopy which are located along a central axis. Since the inner inflatable body is filled with helium to generate a first buoyance, the inner inflatable body can be obviously lifted to a certain height. When a payload connected to the inner inflatable body and the outer canopy with parachute cords falls, the ambient air flows will enter the inflation space through the annular air inlets to produce a second buoyance, which makes the outer canopy open completely. Hence, a secure descending task from even a very low height can be fulfilled if the coaxial double layer parachute can employed. Apparently, the coaxial double layer parachute can be mainly applied to fire and earthquake rescue actions in the cities when low height deployments, risk-free parachuting, and less complicated manual operation are required.
