Abstract :
This paper describes a diagnostic tool (AGETS MBR) designed to isolate failures between Pratt and Whitney´s F100-PW-100/200 engine and related test equipment using an overall system troubleshooting approach. AGETS MBR was developed jointly by personnel at Pratt and Whitney and United Technologies Research Center using a tool called QRS. This paper overviews QRS, highlights its use in the development of AGETS MBR, presents typical AGETS MBR diagnoses, and finally, preliminary AGETS MBR performance results are shown
