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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
