1、Lessons Learned Entry: 0960Lesson Info:a71 Lesson Number: 0960a71 Lesson Date: 1995-05-15a71 Submitting Organization: MSFCa71 Submitted by: Billy Cole / RetiredSubject: Space Shuttle Main Engine (SSME): Integrated Subsystem Test Bed Description of Driving Event: The SSME components were originally p

2、lanned 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

3、 to 1. The test engine could throttle to 50% without requiring a vacuum chamber.Lesson(s) Learned: The use of an Integrated Subsystem test Bed and Full Engine Testing in preference to individual component testing speeds up the development process and produces a high reliability engine that takes int

4、o account subsystem interactions. A special engineering and management team is required to integrate the components and to plan the test program.Recommendation(s): Establish component design through analysis, engineering design, and interface engineering. The build an integrated test bed engine that

5、 takes into account all of the environmental, interface, and operational factors. Meticulously plan and conduct integrated engine test bed firings.Evidence of Recurrence Control Effectiveness: The Space shuttle Main Engines have operated successfully in over 68 flights. Although many minor changes h
