Abstract
Two basic approaches to pattern analysis as related to engine diagnostics may be recognized; a statistical-oriented approach that recognizes data patterns and relates them to known conditions previously observed; and a mechanically oriented approach that seeks through an understanding of symptom-fault relationships to predict data patterns. This paper deals with the prerequisites for employing the mechanical approach. Cases involving turbine engine gas path analysis, vibration analysis, and piston scuffing detection are examined with regard to these prerequisites.
