What I know from how an oxygen generator works, you cannot reliably test those destruction free. So you would have to take some out and trigger them. I would be reluctant to believe that this is the procedure.
- eecc 7y agoRandomizes destructive testing is a perfectly fine and established procedure.
- chopin 7y agoYes, I know, but is this the required procedure for this part? It's definitely more expensive than some visual or electrical inspections. That's why I said I'm reluctant that this is the procedure.
- GhettoMaestro 7y ago> Yes, I know, but is this the required procedure for this part? Please stick to working on front end UI. You scare me.
- soapboxrocket 7y agoThe 787 doesn't use generators, they use sealed single use oxygen cylinders. This is a newer version of the 787 system https://www.rockwellcollins.com/Products-and-Services/Commercial-Aviation/Cabin-Interiors/Oxygen-and-PSU-Systems/Passenger-Oxygen-Systems/PulseOx-passenger-oxygen-system.aspx https://www.rockwellcollins.com/Products-and-Services/Commer...
- chopin 7y agoThanks. However if they are sealed I would assume that you can't test them destruction free, either.
- soapboxrocket 7y agoYes and no. There is a BIT for each unit, (now I don't know the exact details, but this is how I understand/remember it) but the pyrotechnic devices is tested by running a low level current through it to see if it has been fired/failed. The actual seal is verified via testing prior to aircraft certification, and checked in production using helium.
