Aeroengine Diagnosis Using a New Robust Gradient-like Methodology

A new gradient-like methodology has been developed for aeroengine diagnosis, determining the engine health condition, which is defined by degradation from an undegraded state and uses measurements at various sensors distributed along engine. The tools are able to accurately compute, not only degradation, but also turbine inlet temperature, very important novel in field. quality of a given set evaluated, method guide improvement deficient sets. tested representative two-spool turbofan engine, obtaining consistent results computationally inexpensive way. Moreover, robust connection with random noise added data.
