The propellant mixture in each SRB motor consists of ammonium perchlorate (oxidizer, 69.6% by weight), aluminum (fuel, 16%), iron oxide (a catalyst, 0.4%), a polymer (such as PBAN or HTPB, a binder that holds the mixture together, also acting as secondary fuel, 12.04%), and an epoxy curing agent (1.96%). This mixture develops a specific impulse of 242 seconds at sea level or 268 seconds in a vacuum.
A zürrepülõ tankjában meg hidrogén és zoxigén van.
