For production method advancement, we went from hand-assembled stamped parts like this:
To precision-machined and Laser overlaid fastener location when applying carbon nanotube composite RAS skin like this:
We simply live in a totally different world when it comes to advanced manufacturing processes, automation, leveraging of input to output, materials sciences, and computing power plays a central role in all of it. This is why there was a lot of emphasis in Computer sciences while the old inefficient WWII machinery was sold off decades ago.
Even the 1950s and 1960s tooling in Aerospace moved rapidly away from WWII-era machines, especially when you look at the increases use of Titanium and the move into monocoque construction of fuselages, with high-temp engine cowlings necessary to insulate the airframe from radiant hear off the afterburners.
Then in the 1960s, we started doing Electron Beam-welding with one of the more well-known structures being the F-14’s Titanium wing box.
In the 1970s, we started using more boron-epoxy laminates for military aircraft, in addition to aluminum and titanium.
The most aggressive market sector for advancements in materials science and manufacturing methods has always been military aerospace. It really drives progress in electronics, materials, processing power/compactness, optics, RF sensors, man-machine interface, systems integration, production management, and supply-side restructuring.
There are technologies we developed in the 1950s that still haven’t been matched by any of the other industrial nations.
