Programs for Testing an SSME-Monitoring System

A suite of computer programs has been developed for special test equipment (STE) that is used in verification testing of the Health Management Computer Integrated Rack Assembly (HMC-IRA), a ground- based system of analog and digital electronic hardware and software for “flight-like” testing for development of components of an advanced health- management system for the space shuttle main engine (SSME). HMC-IRA units are designed to be integrated into a test facility wherein they enable additional engine monitoring during SSME hot-fire tests. Running on a control processor that is part of the STE, the STE software enables the STE to simulate the SSME Controller, the SSME itself, and interfaces between the SSME and the HMC-IRA.
