Development of Life Prediction Capabilities for Liquid Propellant Rocket Engines. Task 3. Sensor Data Validation and Reconstruction. Phase 1. System Architecture Study

Abstract

This sensor validation and data reconstruction task (1) reviewed relevant literature and selected applicable validation and reconstruction techniques for further study, (2) analyzed the selected techniques and emphasized those which could be used for both validation and reconstruction, (3) analyzed SSME (Space Shuttle Main Engine) hot fire test data to determine statistical and physical relationships between various parameters, (4) developed statistical and empirical correlations between parameters to perform validation and reconstruction tasks, using a computer aided engineering package, (5) conceptually designed an expert system based knowledge fusion tool, which allows the user to relate diverse types of information when validating sensor data. The host hardware for the system is intended to be a Sun SPARCstation, but could be any RISC workstation with a UNIX operating system and a windowing/graphics system such as Motif or Dataviews. The information fusion tool is intended to be developed using NEXPERT Object expert system shell, and the C programming language.
