SPACE SHUTTLE ENGINEERING AMD OPERATIONS SUPPORT 1.3-DN-C0503- 010 DYNAMIC CONTROL OF SRS THRUST TAILOFF FOR SEPARATION AVIONICS SYSTEMS ENGINEERING

摘要

This design note summarizes the results of a study to examine the use of AP (difference in chamber pressure between SRB engines) as a controlling signal to the FCS during SRB thrust tailoff. In addition, the control capability of the Generalized Attitude Control System (GACS) was compared to that of the baseline. Results indicate that the APc signal provided essentially no improvement. However, the GACS is considerably better than the baseline in controlling during tailoff disturbances.
