在冲压式快速空投硬式气囊缓冲技术的基础上,设计了口径可调节的进气道机构,主要包括电池、弹簧、电磁铁、可变电阻的设计,最终建立了进气道机构三维数学模型。 根据空投环境下的压力测试要求,设计了内置式缓冲装置测压系统,进行了测压系统方案设计,该进气道及测压系统具有结构简单、便于维护、体积小、质量小等特点。 该系统满足冲压式快速空投使用要求。

Based on the technology of ram-type quick airdrop rigid air chamber, diameter adjustable air inlet mechanism was designed, which mainly included batteries, spring, electromagnet, and variational resistance. Three-dimensional mathematical model of the air inlet was established. Built-in manometry mechanism for cushioning equipment and pressure testing system project was designed according to pressure testing requirement of quick airdrop conditions. The system has simple structure, easy maintenance, small volume and small mass characteristic, and they satisfy application requirements of quickly airdrop system.
