Title: Apollo launch escape system question
Post by: mako88sb on February 20, 2016, 03:07:46 PM

Did a bit of searching and found some NASA pdf's that go into quite a bit of detail about the LES but there's no mention of what kind of G-forces the crew would be subjected to even in the test results. I found the Orion PA-1 test results that mention a max of 17 g's so I'm assuming something similar for Apollo but someone else mentioned that he heard 25-30 g's. I ended up looking at Col Stapp's deceleration tests that showed a max of 46 g's as the highest ever recorded. Wow! Anyway, just wondering if anybody knows the max G-force that an Apollo crew would of experienced if a pad abort was ever initiated?

This report gives 17-20G loads, depending on when in the launch abort occurred.

Thanks! Never thought to look under abort planning.

Very interesting trivia about the LES: https://en.wikipedia.org/wiki/Pendulum_rocket_fallacy
