Today I posted a copy of the AbTech Jet Engine Diagnostic Demonstration on comp.binaries.ibm.pc. JEDI is the initial prototype of a jet engine diagnostic system for the Pratt & Whitney JT8D-7 gas turbine engine, commonly found on-board the Boeing 737 and DC-9 aircraft. JEDI was developed under AbTech IR&D with the NASA-Langley Research Center. JEDI results from a combined application of the AIM (TM) machine learning tool and other abductive modeling techniques employed by AbTech. It provides the baseline for the development of an overall system diagnostic concept exhibiting the following capabilities: - Fault Detection (*) - Fault Isolation - Degradation Estimation - Sensor Fault Detection (*) - Sensor Fault Isolation (*) - Dynamic Behavior Modeling - Diagnostic Conclusion Confidence Measures The asterisk (*) indicates the capabilities which are included in this demonstration. If you have any trouble downloading this file, or if you wish a copy sent to you, send us your US-MAIL address and we'll mail it to you. A technical background paper and user's manual are also available. ----------------------------------------------------------------------------- Paul Hess E-Mail: hess@adminsun.ee.virginia.edu AbTech Corporation Phone 804-977-0686 700 Harris Street Fax 804-979-3749 Charlottesville, Virginia 22901 -----------------------------------------------------------------------------
