The invention relates to an air-drop protective system. The system comprises a parachute and at least one safety protective device, wherein the safety protective device comprises a safety air bag, an air generator and an impact switch; one end of the safety air bag is directly or indirectly connected with a carrier of the parachute, the other end of the safety air bag is connected with an air output end of the air generator, and the other end of the air generator is directly or indirectly connected with the impact switch. The system not only can enable air-drop objects to fall to the ground more stably and more safely during normal air drop, but also can have a certain protective effect on the air-drop objects, particularly on a pilot when the parachute cannot be opened normally within a set height; wind power has a smaller influence on the system during air drop.
