INTERFACE 2 - Advanced Diagnostic Software
Abstract
JET-X is an expert system for the diagnosis and maintenance of the TF34-100 jet engine as installed on the USAF A-10A aircraft. JET-X uses input supplied by the TEMS (turbine engine monitoring system) installed on the airplane and, in addition, uses data retrieved from the CEMS (comprehensive engine management system) data base that is part of the ground computer support system. Both of these monitoring systems generate alarms which are the starting points for JET-X analyses. As part of an earlier contract, diagnostic troubleshooting procedures had been established for resolving each of these alarms. These diagnostic procedures have been embedded into the JET-X system, generally in a much expanded form. In addition, a number of help facilities have been developed for JET-X to assist the novice diagnostician. JET-X has been designed to be both a flight-line diagnostic tool and a training aid. Although the system is not complete at this point, a first good prototype has been developed, and some field experience has been gained in order to evaluate the system and to guide future enhancements. This report describes the development of the JET-X system, its features and limitations, results of the field trial, and gives conclusions and recommendations for future work. JET-X has been developed as a part of the INTERFACE IIL Contract (F33657-85-C-2131), sponsored by AFWAL/POTA (of the Air Force Systems Command).
