Lessons Learned – Space Shuttle Main Engine (SSME): Integrated Subsystem Test Bed
Year: 1995
Abstract: Description of Driving Event:
The SSME components were originally planned to be tested on a "bobtail" engine. To provide integrated testing, which takes into account the component interactions, however it was decided to add a shortened version of the thrust chamber. The shortened version had an area ratio of 35:1 versus the flight configuration requirements of 77.5 to 1. The test engine could throttle to 50% without requiring a vacuum chamber.
