如题，看机型看到这个，不知道有没人研究过

ENGINE BURST / RIM RELEASE PROTECTIONDamage to Main Distribution Line (MDL):
- in case of damage to a part of the MDL due to engine burst failure or
rim release, the surge flow in the damaged MDL part will induce the
SOV in the damaged part of the MDL to close. The reverse flow check
valve on the damaged part of the MDL will also close in order to seal the
damaged region.
- the surge pressure increases and when the door latch actuation pressure
(1.5 bar - 3.0 bar) is achieved, the doors of the oxygen container
assemblies supplied by the undamaged part of the MDL will be released.
The oxygen mask assemblies fall out and hang from the lanyards in front
of the users. After a certain time the bleed valve closes automatically.
Damage to Riser Line (RL):
- in case of damage to a RL due to engine burst failure or rim release, the
surge flow in the damaged RL part will induce the SOV in the RL to
close.
- the surge pressure increases and when the door latch actuation pressure
(1.5 bar - 3.0 bar) is achieved, the doors of the oxygen container will be
released (except the doors of the oxygen containers in the damaged RL).
The oxygen mask assemblies fall out and hang from the lanyards in front
of the users. After a certain time the bleed valve closes automatically.
