A pre-deployed parachute includes a double-drag balloon parachute with an inflation canopy and a first drag generating space, a universal joint attached to the double-drag balloon parachute by a universal joint, a pre-deployed canopy with a second drag generating space and attached to the universal joint, a load attached to the pre-deployed canopy. The inflation of the inflation canopy allows the pre-deployed canopy to be deployed without requiring height difference and any dynamic energy. With the buoyancy and the first drag generated by the double-drag balloon parachute and the second drag generated by the pre-deployed canopy, the pre-deployed parachute is capable of producing three drag forces, and therefore, the pre-deployed parachute can be brought to a stable condition within a very short time, which prevents the discomfort feeling of a sudden free fall at the beginning stage of the parachuting.
