The paper aims to have in-depth research and exploration on the special inflatable protective equipment for parachute jumping to compensate inadequate ankle protection of paratroop boots and change the situation that there is no protective measures for hips (caudal vertebra and lumbar vertebra), and thus reduce the probability of ankle and hip (caudal vertebra and lumbar vertebra) injuries of paratroopers. A kind of wearable special protective equipment for parachute jumping was developed. According to the actual application requirements, a reasonable design scheme was proposed, including the design of structure, shape, material and molding process. Through theoretical analysis and wearing test, the feasibility and rationality of the design scheme were verified. The structure, material, technology and performance of the special inflatable protective equipment for parachute jumping can meet the requirements of liquid airdrop without parachute, and excellent protective effect was realized after the paratroopers wear it. The special inflatable protective equipment for parachute jumping is a kind of practical, convenient and economical new parachute protective equipment, which is worth popularizing.
