Hi All,
 
Just a quick questiuon about the TYPE D-2 Oxygen Bottle - were these optional equiptment on planes or standard? Additionally when did they first see service and were they considered "walk around bottles"
 
Thanks,

    Sevsral o2 bottles were standard equipment on the B17. They were walk around, each bottle held about 5-10 minutes o2, I forget how much

    John...According to my Illustrated Parts Catalog, the main O2 Bottles called for a G-1...this is the large set of 18 bottles comprising the O2 system on the B-17. (actually four seperate systems connected together). It was a 400 PSI system.

    There were walk-around bottles, which were A-4 bottles, according to the Erection and Maintenance Instructions.

    There was a F-1 O2 bottle attached to the ball turret on the "F" model B-17s. This was changed on the "G"s to allow connection thru the rotating support for the ball turret....a similar connection through the rotating support for the top turret.

    I see no mention of a D-2 O2 Bottle on the B-17G.

    John,
     
    By chance do you have a picture of the D-2 bottle you could post?  I'm trying to figure if it was the long skinny one that looks like a salami or the small round one that looks like a coconut (sorry abou the food analogies, but they fit).  The long skinny one was the bailout bottle.  I've been told that they are still carried on the C-130 and similar planes in the event of an emergency bailout.  The smaller, rounder one is the walk-around bottle.  At least on the B-24.

    Doug, that walk around bottle, and heavy clothing, made a tight fit to get through the center braces on the cat walk of a B24. I`ve done it & it is  not a lot of fun with bomb bay doors open.
    Some times those little incindeary bombs floated around all over the bomb bay & had to be kicked off walk way. Lots of fun!!!!!!!!!!!!!

    Doug,

    Credit line for images at attachment is http://www.bellsaviation.com/catalog/viewcategory.php?categoryid=3

    You'll have to hyper-link to the abve URL, then go to page two to see a D2, A-4 and A-6.

    Take what you like and leave the rest....

    Hi,
    I posted this a few years ago in a discussion about oxygen bottles.  Although it does not answer your question directly, I think you will find it of interest.

    Lloyd, I am not certain about this but I believe every oxygen station, every crew station had a two foot oxygen recharger hose and a walk-around bottle. I can't remember if there were any spares or what stations had the larger bottles. As the years have passed, I can not remember anything about the time spent on B-29's or where the bottles were. Perhaps if I went back an checked some of the pictures, it might jog my memory. One main difference on the B-29's from the B-17's, we were provided a small high pressure "bail out" bottle which had a length of hose and fit in a pocket on the leg of your flight suit. Checking my B-29 school notes,they were small, SLIM, 1800 psi, high pressure and strapped to your thigh. They had a pipe stem end to hold with your teeth. It was recommended that if you were at 30,000 feet or more, you should put the stem under the chin of your mask, while leaving your mask on to prevent freezing your face - while you did a free fall of at lest 10,000 feet. If I have the story straight, you were supposed to hold your breath during the free fall to prevent loosing the bottle when you popped your chute. It took about 35 seconds to fall 10,000 feet.

    I thought I might add this neat sketch that shows some oxygen bottles.   It is part of a collection drawn by my Uncle's co-pilot, Pete Ebersole, about a month after the airwar ended in Europe.
    Cheers,

    I recall the walk around bottle to be shaped like a slightly flattened coconut

    All,
     
    After doing some research I found some information that should answer this question for most people. I will post this under a new thread in the gear section - it will cover 3 types and the regulator...
     
    Regards,
