有工友私信刘工,询问飞机客舱窗户上小孔的作用,刘工查阅了一些资料,整理后,分别向各位工友们简单介绍一下A320飞机和B737NG飞机上“小孔孔”的秘密。
▲A320飞机窗户分布示意图
A vent hole through the inner pane lets the cabin pressure into the space between the inner and outer panes.
▲通气孔在内层窗玻璃上,让客舱压力进入内窗玻璃和外窗玻璃之间的空间。
The vent hole has to be at the bottom when the cabin window is installed.
▲通气孔在底部
▲B737NG飞机窗户分布示意图
客舱窗户共有3层,分别是:
Outer Pane (外层窗玻璃)
Middle Pane(中层窗玻璃)
Inner Pane (内层窗玻璃)
A small breather hole is near the bottom of the middle pane.
▲通气孔在底部
A small breather hole is near the top of the middle pane.
▲通气孔在顶部
The hole lets the pressure between the two-pane assembly stay the same as the pressure in the cabin.
▲通气孔让两个窗之间的压力与客舱压力保持相同
The airflow dampener helps to prevent the window from fogging during flight.
▲气流缓冲器(也叫气流阻尼器)有助于防止飞行期间窗起雾
