Author	Topic: Apollo 11-13 PLSS backpack exact dimensions
chameloon Member Posts: 44 From: Europe Registered: Jan 2014	posted 04-28-2014 12:18 PM I'm struggling to find the exact dimensions of Apollo 11 to 13 portable life support system (PLSS) backpacks (-6?). Every dimension I find is different. I know it is labelled as a Apollo 16 unit, but are those dimensions (diagram found on the internet) also correct for a Apollo 11 PLSS? I find it suspect there is only less than an inch of difference between the bottom and the top side (9.5 vs. 8.75 - side view). Thanks for help!

It can be seen in many photos as a rounded bulge. Karl Dodenhoff's excellent Space Museum website has a very nice dimensioned but large Hamilton Standard drawing.
