Space-Qualified +15V Regulator Worst-Case Analysis

In light of the idea that graduating with an engineering degree only gives one sufficient knowledge to finally learn how to be an engineer, my early learning phase happened to occur with high-reliability systems – spacecraft primarily. Some of the procedures were far more stringent that I later ran into when working with commercial companies. In my case, this was during the late 70s to mid 80s – also a period of great change in electronic technologies and manufacturing procedures and capability. Follows is one of my earlier assignments as a fresh-out MSEE. I was aided by the fact that by this time, I had a few years experience as both a technician and BSEE engineer under my belt.

From my notes circa mid-80s: Taken almost verbatim with names of the guilty redacted. This worst-case analysis was the approved basis for a bird launched a few years after this report was submitted.There wasn’t so much >stuff< up there then …

This report (and associated analyses for the other parts of the system) was a turning point in my career; I became an “independent” contributor after this. Got a healthy raise to boot. 🙂

I must have learned something from my mentors …
