In its broadest context, an engine health management (EHM) system deals with the monitoring, detection, isolation, predictive trending, and accommodation of engine degradation, faults, and failures. Its approach draws from a wide range of engine system disciplines including materials, structures, aero, and controls. Minimizing total cost of (engine) ownership, and increasing asset availability and readiness while ensuring safe operation, are key drivers for the implementation of an EHM system. Relative weightings of these factors vary in importance depending on the end user's operating and business environment, as well as application‐specific needs. Hence, there is no specific one‐size‐fits‐all approach for an EHM system, but rather an array of capabilities that can be assembled to address the specific needs of an end user. The range of capabilities employed in these systems includes not only those that are engine specific, but also those drawn from mathematical, statistical, and artificial intelligence methods that are more generic in nature and have potential cross‐cutting application to other propulsion, marine, and power generation gas turbines as well as rocket and hypersonic propulsion systems. This chapter provides an overview of current and evolving EHM system capabilities available for the spectrum of possible aircraft applications.
