In conclusion, technical challenges that must be addressed if SHM is to gain wider application are discussed in a general manner. Abstract: Predictive maintenance is the novel development from the condition-based maintenance, which is being widely studied in various engineering systems. SAFRAN gathered at the end of 2014 69000 employees in almost 60 countries and realized a turnover of 15.4 billion on the same year1 (see Figure 2). In the process of providing the historical overview and summarizing the SPR paradigm, the subsequent articles in this theme issue are cited in an effort to show how they fit into this overview of SHM. SAFRAN is a high-technology group, currently leading in several fields such as aerospace, aeronautics, defense and security on an international level. Recent research has begun to recognize that the SHM problem is fundamentally one of the statistical pattern recognition (SPR) and a paradigm to address such a problem is described in detail herein as it forms the basis for organization of this theme issue. This introduction begins with a brief history of SHM technology development. The increased interest in SHM and its associated potential for significant life-safety and economic benefits has motivated the need for this theme issue. The past 10 years have seen a rapid increase in the amount of research related to SHM as quantified by the significant escalation in papers published on this subject. However, the majority of SHM research conducted over the last 30 years has attempted to identify damage in structures on a more global basis. Date: Saturday, Septem Sunday, SeptemTime: 8:00 AM 5:00 PM. Prognostics and Health Monitoring (PHM): a. The H2 norm is a good indicator which is sensitive to system input and output. The FEM model of the structure is built and the H2 norm of the structure is defined. Figure 1 A regular 2D frame structure with 11 sensors located on different elements. Electro-Hydraulic Servo-Actuators (EHSA) are currently the most used actuation technology for primary flight control systems of civil and military aircrafts. A wide variety of highly effective local non-destructive evaluation tools are available for such monitoring. Prognostics and health management (PHM) system for single-level aircraft structure and implementation method. Benefits Analysis of Prognostics & Health Monitoring to Aircraft Maintenance using System. Prognostics and Health Management (PHM) Society’s 3rd Annual Doctorial Consortium, 2011.

Aircraft Condition Monitoring via an Electronic Kneeboard. Here, damage is defined as changes to the material and/or geometric properties of these systems, including changes to the boundary conditions and system connectivity, which adversely affect the system's performance. A Model-based Health Monitoring and Diagnostic System for the UH-60 Helicopter. The process of implementing a damage identification strategy for aerospace, civil and mechanical engineering infrastructure is referred to as structural health monitoring (SHM).
