Application of Multiple Handle Gas Path Analysis on a Twill Spool Turbofan Engine

Abstract

In this paper the development of multiple handle gas path analysis, an analytical approach that has two advantages over linear gas path analysis is described. Firstly, it allows all instruments to he used for diagnostics purposes, without having to use one to determine the baseline. The other advantage is that diagnostics can be cross checked against one another to allow greater faith in the result. A conclusion that can be drawn regarding multiple handle gas path analysis is that it appears to be a promising technique. For some faults it appears to give better diagnostics than linear gas path analysis, without going to the complexity of nonlinear gas path analysis. The latter is however more accurate. The analysis of a high performance twin spool turbofan engine, gave rise to a very useful diagnostic. Several fault sets were analyzed and several instrumentation sets were examined, ranging from the minimum available in the cockpit to a much more comprehensive one.
