Hi! I was just watching the SR 71 speed check video and it reminded me of an episode in “The Americans” in which soviet scientists want to get a hand on the design (The cross-section, I think it was called?) of a plane the US is designing.
My question is: How did scientists and engineers at said time (Late 70’s, early 80’s) model air/turbulences/pressure without the GUI we have today?
I know from a friend who is studying mech.eng that software like MathLab allows you to simulate, via FEM, said situations. I saw one of his homeworks and it was a steel beam with different colors showing different pressure points and where it would break/bend.
However, without this visualization, how do you *read* the results? Is it like a partial derivative? Ie: You have numbers for each “slice” in the digital mock-up?
I have tried to find an answer for this before writing the question but either there is none or I missed the right keywords. If you already know a link explaining this, I would be more than glad to read it.
