Description:
An algorithm is derived for the real-time calibration of the engine mixture ratio during SSME ground testing. Because currently used calibration methods are post-test operations, there exists no fail-safe way of predicting at what mixture ratio a planned test will run. It is proposed that the algorithm developed here be used as part of an AECS which could ensure that nearly all SSME tests are run at the proper mixture ratio. In this way, AECS has the potential of increasing the efficiency of the SSME ground test program. This algorithm is an alternative to that presented in a previous paper. In addition to the derivation of the algorithm, an overview of this calibration system is presented along with a discussion of a possible single coefficient calibration system and the list of test stand facility instrumentation necessary for AECS implementation.
