Abstract: A crash attenuation system has an airbag inflatable generally adjacent to an exterior of the aircraft. The system includes a gas generator in fluid communication with an interior of the airbag. The system also includes a vent system having a vent passage supported by the aircraft, the vent passage being configured to allow gas to escape from within the airbag during an impact to a second set of airbags for flotation. The vent system also includes an actuator door for sealing the vent passage, thereby preventing gas from leaving the airbag. The actuator door is actuated by an actuator, the actuator being in fluid communication with the gas generator through an actuator duct. The system operates such that deployment of gas from the gas generator causes the actuator to inflate, thereby causing the actuator door to seal the vent passage. The gas generator is configured to re-inflate the airbag after the actuator door seals the vent passage.

Abstract translation: 碰撞衰减系统具有通常与飞机外部相邻的气囊充气。 该系统包括与气囊的内部流体连通的气体发生器。 该系统还包括具有由飞行器支撑的通气通道的通气系统，该排气通道构造成允许气体在冲击期间从气囊内逸出到用于浮选的第二组安全气囊。 排气系统还包括用于密封通气通道的致动器门，从而防止气体离开气囊。 致动器门由致动器致动，致动器通过致动器导管与气体发生器流体连通。 系统操作使得来自气体发生器的气体展开使致动器膨胀，从而使致动器门密封通气通道。 气体发生器构造成在致动器门密封通气通道之后再次充气气囊。
