My father was in the Navy and worked on aircraft carriers. He tested the catapults and arresting gear. Growing up my sisters and I had no idea what that meant! Carriers are pretty darn amazing.
Watching the Ford hasn't been fun. 5 billion over budget, and commissioned without working catapults or ammunition hoists. Expecting another 5 billion to complete. But they just ordered the next two in the class
My uncle helped design the arresting gear.
Part of his process (way pre-computer-simulation) was to take a model of the carrier, spread talc over the top of it, and play notes on a violin to see how various vibrations would be expected to move across the top of the ship.
(i am so not an engineer & have no idea about any further details/purposes, no use asking me)
I find few things more interesting than military videos. The aircraft carrier, a floating city with an airport on top, is one of my favorites. Watch what your money makes.
