The Shuttle boosters had 4 segments and Artemis has 5. What are the differences in total mass, thrust and burn time? Is the thrust profile (thrust over time) the same?
(This answer assumes the the SLS SRBs are the same as the Five-Segment Boosters (FSBs) studied for a shuttle upgrade...I believe they are, but have not seen this explicitly stated).
The thrust time curves are compared here
- RSRM = Redesigned Solid Rocket Motor (shuttle SRB)
- FSB1 = Five Segment Booster (not sure about the 1)
Reference (a paper by my old boss):
Ignore the part about parachutes. No chutes on SLS boosters.
Thanks to Jörg W Mittag who suggested in a comment that the SLS SRBs might have been derived from the Ares 1 design. I found a plot for that, which looks superficially similar to the one above except for maybe a bigger thrust difference on the "second hump". Also it's a clearer image.
