STAMATIS, ABERIOS, GPAPAILIOU, KMATHIOUDAKIS, KA common feature of all Differential Gas Path Analysis methods is the necessity of measuring a number of performance variables greater or at least equal to the number of diagnostic parameters which have to be estimated. Discrete Operating Conditions Gas Path Analysis (DOCGPA) is an extended version of the conventional GPA algorithms, providing-among other things-the capability to overcome this problem. In the present paper, we describe how this method can be coupled with an engine computer model, in order to perform component directed fault diagnosis. Application to a commercial turbofan engine demonstrates the effectiveness of the proposed method.http://hdl.handle.net/123456789/23293ISI:A1991GU1170002710486710430748-4658engAMER INST AERONAUT ASTRONAUTJOURNAL OF PROPULSION AND POWERJET ENGINE FAULT-DETECTION WITH DISCRETE OPERATING POINTS GAS PATH-ANALYSISjournalArticle1991Δημοσίευση σε περιοδικόPublication in journalΑεροδιαστημική μηχανικήAerospace Engineeringisi - Engineering, Aerospace includes resources concerned with astronautics, aeronautics, aerospace, and aviation.
