BTDT but in 1959-60 era. Testing the ullage pressure regulators for the
early birds, including some that gave John Glenn his first ride or 2. I
don't recall the brand of paper tape recorders, but they used 12at7's &
12au7's by the grocery sack full. One or more got noisy & me being the
budding C.E.T. that I now am, of course ran down the bad ones and requested
new ones. But you had to turn in the old ones, which Stellardyne Labs
simply recycled back to you the next time you needed a few. Hopeless
management IMO, but thats cost plus for you.
At 10k$ a truckload for helium back then, each test lost about $3k worth of
helium because the recycle catcher tank was so thin walled. And the 6
stage cardox re-compressor was so leaky, occasionally blowing up a pipe out
of the last stage that put about 7800 lbs back in the monel tanks.
I considered that a huge waste compared to the cost of a 12au7, then about
$1.35, and raised hell, so I got fired. They simply did not care that a
perfectly good regulator was being abused to death when it took 10 or more
test runs to get one good recording for the certification. At those
operating pressures, the valve faces erode just like the seats in your
shower faucets do in 20 years. Ten such runs and you may as well bin it,
but they didn't.
I am amazed that as many of those birds worked as did. Of course if it
wasn't manned, they didn't talk about the roman candles on the launch pads.
I heard one story that they had to regrade one pads real estate at
Vandenburg & start all over, seems some ID10T had left the cable to the
explosive bolts hanging on the cable tower. Ooops, and theres no off
switch in many of those once the umbilical has been dropped.
