For example, on the "Engine On-Off" (section reproduced in image below) you
see the use of so-called "Deadface Connectors" between the Command
(CM) and Service Modules (SM).
Extremely reliable, robust connectors designed for the space industry,
they are designed to provide electrical isolation before physical separation
such as in this case where the CM and SM separate prior to re-entry. |
Rather enjoyed going through the schematics .. had a bit of a rise in interest when I reached Section F .. thinking about the root cause of Apollo 13.
One of the best jobs I had in the RAAF was being a Technical Spares Assessor for Aircraft Consumable Spares (ACS) managing Passive, Active Components and Connectors. It was fascinating to read all the MILSPEC's that covered Aerospace Components which included Space Grade components which had their own unique MILSPEC's. Space Grade components had really tight tolerances and additional testing requirements to ensure reliability ... you appreciate why the programs cost $$$$$$'s.
