摘　　要：针对潜航器遭遇大幅度掉深险情,探讨了一种爆涨式气囊装置工作原理,通过对潜航器在大振幅内波环境中运动状态分析,提出了应急救生装置所需固态气体发生剂的最小体积及估算方法,以及爆涨式气体发生器及气囊结构的基本原理;确定了选择具有产气率高、气体产物温度低和无毒材料作为气体发生剂,以及耐腐蚀、柔韧性高和耐温高材料作为气囊材料的基本原则。应用分析表明:与传统潜航器应急救援手段相比,新型爆涨式气囊装置具有操作简单、可靠性高以及发挥作用快等优点。The operational principle of a new explosion-type airbag device was discussed that can be used in the dangerous case when a submerged vehicle in ocean is suffering sharp falling deep. Based on the analysis of the movement of the vehicle in the large amplitude internal wave environment, the minimum volume and its calculated method of the gas-generator agent required in the emergency rescue airbag were given, as well as the working principles of both explosion gas generator and airbag structures were proposed. How to select the materials with high gas production rate, low gas product temperature and non-toxic material as the gas-generator agent, and the ones with corrosion resistance, high flexibility and high temperature resistant as the airbag material were determined. Application analysis shows that the proposed new explosion-type airbag device possessed the advantages of simple operation, high reliability and fast action compared with traditional rescue devices.
