Pressure breathing

[Genghis the Engineer]

I'm too many years out of the military game to have access to current information "in-house", but would find it handy to know what the current state of the art, if there is one, looks like for high altitude aircraft pressure breathing systems.

Is anybody able to point me at any accessible documents, or tell me the general arrangement and numbers (pressure, flow, etc.) of current pressure breathing systems, and what they're being used on?

If you put AP3456 Volume 6 Aviation Medicine into your favourite search engine it may well be in there. You can download it as a PDF, but my small phone would probably explode with the size of the doc, so I can't check for you!

[Genghis the Engineer]

Thanks, I've got AP3456 and will have a look. I forgot that it has a medicine volume.

Oh the joys of AMTC and 2 minutes at 30mm Hg every so often before chamber runs....

[Genghis the Engineer]

Thanks again 2Planks, I've got a reasonably recent copy of AP3456, and it indeed is extremely thorough. Good call.

Thanks Genghis, love it when a plan comes together!

Beags, All I remember of AMTC was a Stamford curry and Ruddles County

2Planks...............

And I bet the rest of your course in the decompression chamber remember it just as well!!

[BEagle]

Stamford curry and Ruddles County was indeed de rigeur!

The poor docs who went into the chamber with us must have had to suffer over and over again, because every course did the Ruddles and curry session!

Sympathy for Doctors................???

Amazing...............!!

Stamford curry and Ruddles County plus high altitude = explosive decompression.

ISTR going to Oakham for curry and a few pints of 'Riddles Faintly Peculiar'...

Salute!

Hope the pressure oxy system doesn't become an excuse for some future accidents, The new systens for the F-22 and F-35 seem to be overkill to this old fart.

Ask about A-4 and F-101B and F-106 and other jets.. We had constant pressure with the nose hose, and no big deal. The planes were supposed to fly way high, and pressure suits were on the kit,. Tink the F-104 was same, and maybe the Lightning.

Only thing my bride and I suffered was the delay ear block and we soon learned to val salva in our sleep!

I only ran into the pressure breathing is another plane besides the VooDoo, and it was the A-37. It had the diluter-demand regulator like the trainer. We routinely came home at 25K on one engine and the system had positive pressure from about 22k on up. If we went up to 30k for optimum single engine cruise, the pressure was very constant and no big deal.
