The objective of this program was to develop a performance diagnostic system to analyse gas path performance and to recommend economical component replacement and/or modifications to minimize overhaul costs by increasing post-overhaul acceptance rates at the Oklahoma City Air Logistics Center (OCALC). The diagnostic system utilizes a computer simulation of the J75-P-17 engine which was developed using experimental data from five J75-P-17 engine builds tested at the AEDC. The computer simulation is the heart of the diagnostic system and provides performance partial derivatives to aid in evaluating changes in component behavior. Implementation of the diagnostic system at the OCALC is in progress.
