“…Although it is possible to anticipate failures in the near future through the behavioral modeling of systems coupled with fault-detection algorithms [28] [29], but the better way is developing high reliable, high power density power electronic devices. For example, SiC based semiconductor [30][31] device is very promising since it can provide a significant reduction of switching losses, high temperature tolerance and fast switching capability.…”

In recent years, the electrical power capacity is increasing rapidly in more electric aircraft (MEA), since the conventional mechanical, hydraulic and pneumatic energy systems are partly replaced by electrical power system. As a consequence, capacity and complexity of aircraft electric power systems (EPS) will increase dramatically and more advanced aircraft EPSs need to be developed. This paper gives a brief description of the constant frequency (CF) EPS, variable frequency (VF) EPS and advanced high voltage (HV) EPS. Power electronics in the three EPS is overviewed.

“…The value of health monitoring can take a variety of forms as presented in Table 1. However before any proposals to adopt health monitoring is taken, it must be articulated in the form of an economic justification which is often gauged by a Return (Vohnout et al 2008) where prognostic approaches to EMA are assessed against analyses of the potential ROI.…”

The development of health monitoring technologies for aerospace systems creates a number of challenges for the community of engineers and technical specialists as they seek to integrate the technology into well defined working practices. These challenges do not just extend to the technical, but require a number of commercial questions to be addressed. It is of vital importance, that there is a clearly identified need for aerospace health monitoring, both from a technological and commercial viewpoint. If these needs cannot be identified, then any attempt for marketing health monitoring as a necessary future technological requirement is doomed for failure. Health monitoring technology will need to either deliver significant cost saving benefits to the aircraft operator or demonstrated increases in aircraft safety. The objective of the paper is to provide an assessment of the commercial benefits and development of aircraft landing gear health monitoring. The commercial need and challenges for health monitoring systems are explored in this paper within the context of a changing aerospace maintenance industry and the role in which new systems technology will play. The key findings of the research study are that within the aerospace industry there is a desired paradigm shift within aircraft maintenance towards offering maintenance systems with predictive capabilities. This maintenance revolution will not just incorporate new technologies, but will result in aircraft maintenance packages tailored towards individual customer requirements. The study illustrates the state-of-the-art in health monitoring currently restricts aerospace integration and a number of key technical and commercial issues need to be addressed. Predictive health monitoring offers a variety of commercially benefits for maintenance providers, aircraft operators and manufacturers. However, in order for these benefits to be realised increased transparency in maintenance related information is required between these key players.

“…Prognostics and Health Monitoring (PHM) is a technique which uses observations of measurements to assess health state and develop a prediction of impending failure of chosen components [1]. PHM has become a great field of research due to its capability of health assessment and failure prediction, generating technical and financial benefits for any kind of plant.…”

A model-based approach to Prognostics and Health Monitoring (PHM) for an electro-hydraulic flight control actuator is presented. The aim of this paper is to show a model-based methodology to detect, diagnose and prognosticate a fault in an electro-hydraulic primary flight control actuator that precedes an imminent failure. The model-based approach is versatile and can be easily applied on another system, whose model is available. The PHM solution proposed is dedicated to health monitoring and failure prediction of a generic primary flight control actuator. This model-based approach systematically assesses health state and the Remaining Useful Life (RUL) and consists of developing a model of the system for different flight conditions, the introduction of the failure mode. The RUL calculated is a time-to-failure whose confidence level depends on several conditions, such as model fidelity, sensor noise and precision of the data recorder. 12
