Having trouble sleeping so here's a data sci nerd story for you all.
-
-
Supersonic tunnels are far easier to operate. Transonic is much, much harder. (The trans is always annoying lolol).
-
A dynamics tunnel requires more than blow-down designs. And the tunnels are so complex tbat non-rigid models are a no-no. If one breaks...
-
So most of the aerospace research is done at Langley's TDT. For an operating cost of about $270,000/hr, iirc.
-
A while back, I got a chance to play with some data pulled off a test done there. It was for the F-35 tail empennage.
-
The tests cost in the eight figures to run. The resulting dataset was nothing more than an Excel file.
-
So when you're complaining about hashtag horribleness with some cloud based database service or something...
-
Just remember that the US government dropped $10+ million to acquire some data and then shoved it unorganized into a .xls file.
-
To study just one part of a fighter jet. And then they paid another $1.5 million for me to re-analyze the data... to yield the same result.
