Space Shuttle SRB Cutoff and separation

  1. Mar 15, 2008 #1
    When a space shuttle launches, how is simultaneous SRB cutoff assured so as not to create an asymmetrical thrust situation? (assuming that SRB cutoff occurs prior to separation).

    Since the SRB is a solid propellant, there's no shuting them down once the firing commences. That being said, their thrust profile is tailored such that they are providing less than 10% of their max thrust at the time of separation.



    So it appears, and makes sense, that the shuttle's thrusters take over yaw control until the separation has completed.
