Abstract
Literature on PHM is focused on research dedicated to the definition of new algorithms to achieve better failures prognosis or earlier and more accurate fault diagnosis, but lacks of examples on the design of novel PHM frameworks and the practical issues related with their implementation. This paper describes a roadmap for the design of a novel Prognostics and Health Management system while making reference to a real-case scenario applied to electro-mechanical actuators for flight control systems.
Highlights
Literature on PHM systems is mostly focused on the research for novel algorithms or new methodology to isolate a particular fault in a wide range of application fields
This paper describes a generic framework for the design of a novel Prognostics and Health Management system while making reference to a real-case scenario involving the definition of novel prognostics and diagnostics routines for electro-mechanical flight control systems
The case study used as reference for this paper is the development of a PHM system for electro-mechanical actuators for flight control systems for a new regionaltransport aircraft
Summary
Literature on PHM systems is mostly focused on the research for novel algorithms or new methodology to isolate a particular fault in a wide range of application fields. The aim of the first type of research is to provide more robust or more accurate RUL predictions, or to lower the required computational effort The latter is instead often focused on the results achievable through simulated data or through the analysis of data-sets coming from well-prepared experimental campaigns performed under laboratory conditions. Literature on the possible approaches to design and validation of a novel PHM system is sparse and few contributes can be found This is especially noticeable in aeronautic applications, where issues like the difficulty of obtaining meaningful in-flight data often puts a cap on the possibility to validate the health monitoring routines developed through simulations or laboratory experiments. The programme, founded through Clean-Sky 2, is aimed at evaluate the feasibility of such a technology for civil aviation applications, prepare a demonstrator and test the integration of the PHM routines within the aircraft systems
