The Taming of the Screw (2000)

Aside from the article itself being interesting, it is nice to see bits of the old internet resurfacing from time to time.

Coming from ColinWright, I was more than half expecting this to be about kinematics of rotations and translation, well, screw theory, no Lie (*). Nonetheless this is going to be a good read.

An Akula class submarine, mentioned in the article, an uncharacteristically silent Russian attack submarine, was leased out to the Indian navy. I remember that there were intelligence failure from the Indian side that led to the leak of propeller acoustics of 'some' submarines - data for the Kilo class and the Scorpenes were leaked, not sure about Akula.

(*) In the off chance that the other screw is interesting too, there is this https://archive.org/details/theoryscrewsast00ballgoog to take for a spin, especially for those who have enough time on their hands.

This essay must be quite old:

"... our newest generation of submarines, the Seawolf-class, does not even use propellers. Neither will the future generation, the Virginia-class, still on the computer design screen."

The first Virginia class submarine was commissioned in 2004. [0]
