直升机座舱气袋系统

Inflatable System for Helicopter Cockpit

直升机座舱气袋系统经过较长时间的发展,已经开始装备部分型号直升机。作为限动系统的辅助设施,它能很好地保护飞行员,减少各种损伤,尤其是接触性损伤。气袋系统发展概况在飞机碰撞时使用气袋系统来提高生存率的思想已延续了50年。从早期先充气的气袋系统到自动充气气袋系统的研究历时10年时间。70年代曾出现为麦道DC-10设计制造的原型座椅气袋系统。随后,美陆军及海军开发了一些军用飞机气袋系统,其中之一便是可充气身体及头部限动系统(IBAHRS),它包括了限动系统中悬挂在肩带上的小气袋。气袋被用来拉紧安全带,并限制头部在碰撞时的转动。

Inflatable, restraint system may provide the need of improvement in restraint system performance. Recently, U . S Army and Navy have developed some inflatable restraint designs for military helicopter . One of these is IBAHRS, which consists of small air bags mounted on the shoulder harness straps of restraint system . The bags are designed to take slack out of the restraint and support the head .
