ASYMMETRICAL BOOSTER ASCENT GUIDANCE AND CONTROL SYSTEM DESIGN STUDY VOLUME III SPACE SHUTTLE VEHICLE SRB ACTUATOR FAILURE STUDY

摘要

Volume III documents investigation of single actuator failures on the Solid Rocket Booster. Both square pattern (n) and diamond pattern (<>) actuator configurations were analyzed. It was determined that for failures occurring near or prior to the region of maximum dynamic pressure, control gain adjustments can be used to achieve virtually nominal mid-boost vehicle behavior. However, near staging, a distinct worst case failure condition was established that could significantly delay staging. It is recommended that the square pattern be retained as a viable alternative to the baseline diamond pattern because the staging transient is better controlled resulting in earlier staging.
