Reducing the turnaround time for the Shuttle Orbiter main propulsion system at Kennedy Space CenterThis paper presents steps currently being implemented to reduce the processing time of the Orbiter Main Propulsion System. Given the projected increase in launch rates of the Space Transportation System (STS) in the operational era, average turnaround time from arrival at Kennedy Space Center to subsequent launch will have to be significantly reduced. In many STS flows to date, a pacing system has been the Main Propulsion System consisting of the three Space Shuttle Main Engines (SSME's) and the Main Propulsion Subsystem (MPS) connecting the SSME's to the Orbiter/ground and Orbiter/External Tank interfaces. This paper summarizes procedural, hardware, software, and requirements changes being incorporated at Kennedy Space Center (KSC) to reduce the processing time required for the MPS/SSME systems. Specific examples from each category are cited to illustrate the impact of the improvements on MPS/SSME processing.
