1950's Electro-Mechanical Bendix Aviation Computer

Apologize if this was shared before (search didn't provide any mentions).

If you are amazed by how human beings pushed limits, this is a good read + pictures about the internals of Bendix Air Data Computer used to calculate aviation data in fighter planes. Kudos to the engineers of those times.

Intro paragraph from the blog:

Quote:How did fighter planes in the 1950s perform calculations before compact digital computers were available? The Bendix Central Air Data Computer (CADC) is an electromechanical analog computer that used gears and cams for its mathematics. It was used in military planes such as the F-101 and the F-111 fighters, and the B-58 bomber to compute airspeed, Mach number, and other "air data".

It might be worth for us to look into a possible "HP 48GC" for gears and cams version...
