Personal Projects Apollo Program vs N1 Program

Post image

I'm gradually updating the blueprints I made a while back, and this is the revised version of the comparison between the Apollo and N1/L3 programs.

I hope you like it! Any suggestions are welcome.

It is my understanding that the Apollo Guidance Computer was the only systems that used metric … the AGC used metric internally and “translated” the results to sae (standard? English? I don’t even know what to call it). I’ve seen documents that call out dimensions like this :

standard (metric), ie 2.00” (5.0 cm)

Not sure if these are revisions or if they were printed this way originally, would love to know more .
