Yeah, I like swimming in the deep end.
Those of us who have a history of running multidisciplinary
engineering projects usually know better . . . your mileage won't vary
after you get some history behind you . .
Perhaps I should name the project "Icarus"?
1/Icarus, i. e., the reciprocal thereof . . .
The altitude is only a small part of the thing.
. . . groan! . . . -100ºF is only a small part of it huh?
The atmospheric profile shows some interesting things. In the
Troposphere, the temperature drops pretty steadily until around 10 Km,
then it tends to stay pretty consistent until 20 Km. Above 20 Km, the
temperature actually rises somewhat until around 50 Km, at which point
it drops again until around 85 Km. At this point it becomes the
Thermosphere, in which the temperatures rise dramatically - they can get
from 500 to 1500 degrees C. The thermal profiles are by necessity very
general.
So if temps were a very big factor, I'd want to get the balloon through
the 10 Km area pretty quickly, and up to around 30 and a half Km where
it's a little "warmer".
Nice try no cigar.
I'm not breaking any new ground with the idea of launching anything. My
intentions are the research and payload integration.
Welp, good luck with it Mike - Keep us posted.
Will do.
By the way I have a ping-pong ball size experimental load for you if
you ever actually get past the RRAP bafflegab stage and do a launch.
Cockroachs are incredible little critters which reputedly can survive
environmental extremes (temps, pressure) for short periods, on the
order of a few hours. They're everywhere and finding a sturdy specimen
is a no-brainer out in the landfills. When you're ready to go let me
know and I'll grab one and name him "Leonard", package him properly
for a trip to near-space and pass the package to you.
If you break 100,000 MSL we'll ship Leonard off to Sean O'Keefe at
NASA so that O'Keefe can pin astronaut wings on Leonard.
.. . . 10-4 . . ?
